V70 tdi. Donkey demolition.

Recommended Posts

Neither did I till I saw it on the bay. It’s odd, I have no interest in a Xc but this is right up my street. We do tow an event trailer with it, so we do quite a lot of towing across wet grass. Never been stuck before, but awd will give a bit of piece of mind. 😊

Not sure what fluid you've used in the geartronic box, but make sure it's JWS3309 'compliant' , as they are fussy gearboxes.

Old Derv V70 - Hope you get her sorted, my cam & crank seals have just started weeping (insert sad face)

. But it’s worth remembering it’s done near a quarter of a million miles, so something related or nearby that’s been disturbed is definitely still a possibility. .

oh yes. 28 litres total. If that doesn’t sort it out it will be off to Bristol transmissions. Plan A was to learn I up on box rebuilding on it, whilst the Throbber provided safe reliable transportation for all the family. But that’s gone out the window.

I seem to remember reading that the tyres on these have to be within a few mm of each other or else the transmission suffers really badly.

 

Post number 6 in the link below explains it better than I could.

Wtf, the tops of the valves have come off?

The tops of lots of buckets have yes. They are wafer thin.

We think...Getting the timing bang on with the cambelt change raised the cylinder pressures enough that a lunar tappet bucket decided it had had enough. The skeleton wanking was not injector knock but a fucked bucket fucking off and letting the cam open the valve directly.

Then the cheerful bits of shrapnel danced merrily around the rocker cover finishing off most of the buckets around and then wedging the cam, so timing slipped, pistons hit valve.

stripping the head off to see the state of play. Got some hours in after work, but was defeated by the turbo, I just didn’t have a big enough lever, so will attack that later.

What a hilarious description. Tragic what's happened but I'm pissing myself here.

I’ll let you have it for the same as last months garage invoice? Literally giving it away.... 😁

Anyway, off with its head!

And it’s not too bad. Can’t see which piston clashed on piston crowns or valves. It’s a big old lump to lift out on your own. It would have been a lot lighter without the exhaust manifold and turbot, but there was one solitary 12mm nut on the manifold to block that I just couldn’t get to. I do need to admit that the whole shebang did get a lot lighter once I’d undone the turbo drain pipe. Ho hum.

Anyway, have you seen my honing marks? Not bad eh.

Plenty of damage up top though. Reprofiled cam.

Ah, from one ol' V70 owner to another... a right shame about the wafer-thin tappets and bits and resulting carnage. Eagerly awaiting the coming of fruition of cunning planses.

Still tho. This is the first time I hear/see an engine giving up by dying tappets spraying their guts about. Can't be very common, shirley?

A couple of hours on the new one today.

pulled out the pela and pulled out 3 litres of atf to replace with clean. I’ve now done this 7 times within 1000 miles and the box holds about 8 litres total so you’d expect it to have a bit of colour to it by now...

6AC73535-2BE6-4A03-9BBC-08A67B3B5A0A.thumb.jpeg.795df4bec738ce386e69fd5ca8fcb0c7.jpeg

Nope. About the same as the first lot visually. We will persevere though as the box has greatly improved, to the extent that the only worrying symptom is a reluctance to reverse up hill. It did strike me that the only time the new fluid is flushing the reverse circuit is when you are reversing, so the procedure now following the fresh fluid is to immediately reverse in as varied a manner as possible (to be working everything whilst the fresh fluid circulates for the first time) for as long as possible. The main result of this however is to have convinced everyone on the estate that I am a certified nutter. The burger van bloke even waved me down to ask me what the fuck I was doing as I passed him, backwards, for the third time in as many minutes.

New* power steering pump fitted, now lighter and not lumpy, much nicer. New* topmount bush fitted which removed the big engine wobbling around knock. It’s really quite a nice drive now.

Mot next, then I will need to investigate why the turbo is on or off. And the aux belt (which has been heavily oiled from the ps pump) looks pretty ropey so should probably investigate the state of the more important ones. And then start prodding the Haldex. Plenty to do.

We’ll start with a little housekeeping...

as I may have mentioned I’m relatively recently moved into a new work area. (In truth, my first workshop area/facility for over a decade. Excited? You betcha ) This of course involves a modicum of hard wired air. This has been sitting connected for a week. Zero loss. That’ll do for me.

right then, the postie. Brought this selection of shiny newness

All the way from Germany, because they would supply and deliver 10 buckets for the price of 1 UK sourced one. Well, not quite, but nearly. German engine I suppose.

He also dropped off this

Meet Donkey. Donkey was found languishing on page 3 of retrorides classifieds. Donkey is poorly also, having shat his gearbox.

But donkey has a good heart. But not for long. Poor donkey.

In fact, that’s not all that is good on donkey, check out the minty freshness of that interior!

Spoiler! Load liner! And is that a dog guard I see? I have 2 dogs, both are fine in the car, but both are big enough that they don’t want to share an area. So they are quite mobile. Then you leave them for a bit and they pass the time by chasing each other around. And then there is absolutely no point telling sctheyounger she can’t treat it like a bouncy castle /jungle gym / skip. And I treat it like a van. So yes, I’ll be needing all that interior. Any how, the trouble makers.

Of course, having arranged a car for the engine, my eBay app on my phone (about the most irritating thing in the world )went ping. Reconditioned* cylinder head for less than my max cylinder head bid. So I bought that too. Sturdy PayPal bill this month then, but all works towards The Master Plan. I think I’ve now had the use out of the app and will now delete it!

So today I have 3 Volvos, one mostly works but has issues and a mot on Tuesday, and the other two are fucked. Hopefully this is the low point of the plan.

Lots to do. 😁

It didn’t rain. I got Saturday and Sunday afternoons off. Game on.

More evidence of past catastrophe and bodgery on the Throbber

That’s radweld round the bottom hose fo sho. 

I need to point out that I have never done this before, and have a “do it slower to do it quicker” attitude, deliberately, so it took all yesterday afternoon to get it to the point where I’ve done all i can without toms engine crane. The most difficult bit, by far was the lower starter motor bolt. Probably took an hour on it’s own.

Having ground to a halt with the Throbber I got personal with Donkey. And having done it all once everything went much more quickerer.

And is now also pretty much ready to hatch out. Current plan is to pull the block out the Throbber, pull the block and trans out of donkey, take the trans off and discard, put the new cambelt etc on it while it’s on the stand and then put it in the Throbber. Not a 5 minute job it seems, I proper ache right now.

      As you may have read in the 'Can we save this?' thread, the answer was 'Yes we can!'
      Someone on this forum who wishes to remain nameless, fronted the cash to rescue this little Mazda from certain doom at the hands of a banger racer. I've taken custody of the car, but will make sure they get their money back as soon as is physically possible.
      Perhaps once it's running right, I'll look at some sort of roffle to find it a new home and pay back what it owes me and them.
       
      Although it had been sitting 5 years or so, it went through an MOT, so that's a good start.
       
      Known faults.
      - Alternator is kaput. Shouldn't be too hard to find a refurbished one. Presume battery knackered too.
      - Wheel bearing grumbling. 
      - Running like crap. Will replace fuel and vacuum pipes and add fuel filter. Then perhaps a carb strip down and rebuild. Aisan 980 carb as far as i know, same as the Toyota was,
      - Flat tyre. 
       
      It's currently sitting outside with a flat battery and no fuel, so that's not a good start!
       
       
      As I have very little talent, time or money, and suggestions / help greatly appreciated.
       
      These are the pictures I have so far - looks good but it's a lot more dull in real life...

      I've had various threads on the go for different collections this year, but thought I'd condense my threads into one manageable thread to document my ham-fisted tinkering.

      At the turn of the year I was driving a nice, dependable, modern 2011 Peugeot 407 and no other vehicle. It was nice enough, but boring as feck. I'd bought it after a series of disastrous heaps in the awkward age bracket of being new and valuable enough to worry about but old enough to be fucked. The 407 was just too new, too bloated and dull. I had a hankering for old metal, my Mineral Oil withdrawal pangs were strong.

      From January I started looking, there were eBay bids, missed reserves, wasted trips from Gumtree and other such nonsense. I happened on an automatic Rover 216 GSI with one giffer owner from a year old. The chap was giving up driving at 93 years old and his grandson was moving it on. I bid, and failed. It was in London though, about 420 miles away so I wasn't all that bothered. Of course when he offered it to me for my losing bid after the winning buyer was a no show I said yes. I was on the Megabus down to that London overnight for about £15. I hung about in Liverpool Street station like a mad shivering jakey until my train out to the suburb for my first sight of the new steed. It was battered outside but had been well looked after. A frankly insulting amount of cash changed hands and I was away up the road.

      We had many adventures together, it was dependable and it whet my appetite for interesting old motors again and proved that the very bottom end of the market was navigable if I had the patience to wade through the sea of shit to find the odd pearl.



      The 407 was still on the fleet at this point but I was covering a lot of miles in the Rover, with a long commute though the fuel economy wasn't ideal. When a friend's mother was looking for a new diesel saloon to replace the faithful old Xsara she had a scheme was concocted. I sold the 407 to her and was on the hunt for an interesting replacement.

      When I was growing up my dad had a succession of hopeless shitters, indeed I was brought home from the hospital as a newborn in a brush painted Skoda Super Estelle. The best car he had was a red XUD Peugeot 405 with air conditioning and electric windows. So when I found a 1994 GTXD advertised by someone who could actually compose a car advert in the fashion you would expect of a human being educated to a Primary School level, I pounced.

      Of course I couldn't buy a car just down the road so it was on the train to Birmingham. First class no less. I stayed in an absolute flea pit of a hotel and drove up the road the next day. This was a proper bit of nostalgia and a really practical borderline classic car. It had been fastidiously maintained by the previous owner. Apart from there being a hole where there was once a stereo and the lack of working air con it was a pleasant drive home.

      Given their relative scarcity and how dependable this one has proven so far, it's a keeper, I'd struggle to part with it.



      Two cars just wasn't enough to worry about, so this Citroen C1 was acquired. Pure Aleppo spec. A camel can go for weeks, or months without stopping at a watering hole, the C1 has a similar thirst for Motor Spirit. Man maths were employed and worked out that it would easily* pay for itself.




      There have been further movements, I'll recap them shortly. I should probably do some work.

      To mark the genesis of my fleet project thread I here present my new car: a 1997 Nissan Micra Shape-


      It really looks that good. There is a reason for this: its previous owner was an old lady who loved the thing so much so she made every effort to keep it in good shape. It originally came from Fleet in the GU postcode which suggests to me it was bought by the present dealer at auction, hence arriving down here in Kent. Before seeing the car I checked its MOT history and its only fails were thanks to broken stoplights, which shows me that it was very well cared for. I suppose an example of this was that on the last MOT, an advisory was a corroded rear silencer. The silencer on the car when I saw it was new. Methinks the lady wanted to keep it as good as possible. It was kept in a garage and so all the bumpers and black trim are very black and the tyres are in very good condition. Spare never used! Also included a free Dettol first aid kit from 1997.
      This car has 15000 genuine miles on the clock. We clocked over 15000 during the test drive! The lady owner really only trundled around her village in it and the MOT shows that it only did some meagre miles between tests. This, of course, came at a price. We saw a cherry red Micra from 2002 at the same dealer. Paint was shoddy and when they washed it the boot had massive sections of bare metal and it wasn't very happy. This car, however, is in fabulous condition and there was no contest between the two cars- it really is that good, inside and out. Immaculate interior, driver's airbag, cassette player... all there and all functioning (apart from cassette thanks to new battery and failed display). This meant that I bought it for £1600, £100 over what was my uppermost limit, but I knew I wouldn't see another like this that was in as good shape for a fair while. It was priced very ambitiously, at £1990, so I'm content in the fact I managed to slash a few hundred off the price. There wasn't that much paperwork though. All the dealership received was the logbook with 3 service stamps from 1998, 1999 and 2000, the radio key pass, a National Trust sticker, and the original paperwork holder. I suspect the old lady died and had her car auctioned, and the massive file of paperwork is now someone's egg carton, along will everything else she owned.

      As always, this car isn't exactly in showroom condition. While the inside is great and the floor is solid, and the underseal is in great shape, the not undersealed parts need a small looking at. Mainly the rear of the driver's side sill. It's really the only bubbling on the car. I suspect a well aimed stonechip managed to fester over the wintery salted roads, making it rust even more. It's around the size of a 5p piece, and will give me the opportunity to spray the insides of the sill with some chain oil to prevent any further corrosion. Behind the fuel tank there are a few rusty joints- places where the spraygun cannot get paint onto- which some Vactan and Dynax should put to rights. Alternator belt looks original because of the cracking and Nissan badges and will need doing soon as well as the front plate. As much as I like the 90's font and original dealer surround, the dishevelled R and general water ingress is a persistant MOT advisory. It could be the MOT station being strict (and most likely is considering there's a Saxo down the road with far worse blackening), however for the sake of peace of mind and all that, I'll get a new one made. The rear has already been replaced indicating this has happened before.
      All in all, I think this is a nice plucky motor. I'll have it by the end of the week; just got to sort out tax, insurance, and it's going to have an MOT. As part of the deal it's getting the MOT and an oil and filter change which will be something ticked off the list. It has some love scratches and chips here and there, but it drives well, is stiff and controllable, and should make out to be a nice summer project!

      Well I've been meaning to sign up here in forever, but kept forgetting. Thanks to someone over on another forum I frequent poking me about it recently the subject was forced back into my very brief attention span for long enough to get me to act on the instruction.

      I figure that my little varied fleet might bring you lot some amusement...

      So...we've got:

      1993 Lada Riva 1.5E Estate (now fuel injected, as I reckon the later cars should have been from the factory...).
      1989 Saab 900i Automatic.
      1987 Skoda 120LX 21st Anniversary Special Edition.
      1985 Sinclair C5.
      2009 Peugeot 107 Verve.

      Now getting the photos together has taken me far longer than I'd expected...so you're gonna get a couple of photos of each car for now, and I'll come back with some more information tomorrow when I've got a bit more time...

      Firstly...The Lada. Before anyone asks - in response to the single question I get asked about this car: No, it is not for sale. Took me 13 years and my father's inheritance to find the thing.



      Yes, it's got the usual rusty wings...Hoping that will be resolved in the next couple of months.







      Next, a proper old Saab. One of the very last 8 valve cars apparently, and all the better for it. I've driven two 16v autos and they were horrible - the auto box works sooooo much better with the torque curve of the 8 valve engine. Just wish it had an overdrive for motorway cruising...






      Next up a *real* Skoda...back when they put the engine where it belongs, right out the back. In the best possible colour of course...eye-searingly bright orange.





      Seat covers have been added since that photo was taken as it suffers from the usual rotting seat cloth problem that affects virtually all Estelles.

      Then we have possibly the world's scruffiest Sinclair C5...



      Realised when looking for this that I really need to get some more photos of the thing...I use it often enough after all! We have a dog who's half husky, so this is a really good way of getting him some exercise.

      Finally - again, I really need to take more photos of - we have the little Pug 107.



      Included for the sake of variety even if it's a bit mainstream! First (and probably to be the only) new car I've bought, and has been a cracking little motor and has asked for very little in return for putting up with nearly three years of Oxford-Milton Keynes commuter traffic, before finally escaping that fate when my housemate moved to a new job. Now it doesn't do many miles and is my default car for "when I've managed to break everything else."

      I'll fill in some more details tomorrow - I warn you though that I do tend to ramble...
