Well that makes Captains oil pump look brand new!

 I think your main killer there would be mega low oil pressure once it warms up- if you don't care and just need it to get there then whang it back together, lap the valves in hard and stick the thickest treacle oil you can find in the sump and hope for the best, keep the throttle pressed as lightly as possible and the revs low.

 

--Phil

I think Triumphs generally have low oil pressure especially at idle once hot, it's why they never had oil pressure gauges, they had an ammeter instead where a third gauge was fitted. BMC stuff often had oil pressure gauges and they just make you paranoid. Worry gauges as a friend used to say. It is much better that you don't know!

Well, low as in none.. but there would be oil flow so as long as there's something stuck to the bearing surface it should be able tolerate light loading for a short distance

 

It would probably end up being one of those engines you put back together, expect to run 50 miles and it goes on until it's removed 5000 miles later in preference of something less worn out

Confucius say: Driver with one oil gauge, always know pressure. Driver with two oil gauges, never certain.

Christ, That looks like it was pumping sand...

That's a pump that's been run dry. Your pump looks like it's never been run dry but was pumping some very dirty oil for some time. 

Going by your pics and in your state of financial ill health I'd be doing the following. Rebuild the bottom end with all new shells, your shells are fucked but the journals don't look too bad. Use a proper assembly lube too go give everything a chance at first startup. Hone the bores and refit the pistons and rings as is. Replace all oil seals and gaskets. Refit any old head after lapping in the valves. Remember that the head of your original engine looked totally fucked but the engine was still running with that head when the bottom end failed.

That will give you a running engine that should last for a thousand or two miles. It might smoke and use oil but you'll have a running driving car again for probably under £100. It'll turn a liability into an asset and take a bit of pressure off you. Use it sparingly and you'll have a backup car for the acclaim for some time to come. If finances improve you can properly rebuild another engine and if they don't then you'll have a running driving fully legal car that's an asset that you could sell.

Two stories of knackered engines.

Mate #1 many years ago had an MG midget with knackered big ends. Shells worn out and journals miles out of spec. He got a full year commuting out of it by dropping the sump and lobbing new shells in it once a month for a whole year. It was still running like that when he sold it on. 

Mate#2 worked as a diesel fitter for the council. A bin lorry lost its sump plug at the tip and seized  solid and my mate had to rebuild it. It got new pistons and liners and my mate wanted to get the crank ground because it looked like a ploughed field. His boss refused because of budget and insisted he cleaned up the journals with emery cloth and just throw new shells in. This he duly did and much to his amazement that wagon ran constantly for the next three years without that engine having a single problem.

I have a honing tool if you need a hand cleaning the bores up. Just drop me a PM if I can be any help.

This was the sort of thing my late grandpa used to do. I remember helping him with OYM145Y a BMW E21 323i he brought back from Spain in 1992-ish (swapped his LHD BX for a the Beemer as UK reg & RHD); it started knocking and him and his best mate stripped the engine down at home, and refinished the crankshaft journals with progressively finer emery cloth, checking roundness with a micrometer to the next size down. It took them both about a week as I seem to remember they had to supervise me lapping the valves and a few small top end job. He used it for another year or so before PXing it against a new mingebag spec XM diesel, and was on the road until 1998.

Sorry for Fred Hijack

Also OT....my oul 635CSi was "OYM 71Y". Was your Grandpa's E21 supplied by Motortune Ltd. by any chance?

That I can't tell you. He moved to Spain in an Avenger in 1987, then in 1990 he bought a BX, and moved back to the UK in 1993 when he bought the 323i back, and first thing he did was have new plates made up.

Suggests #2 spent a good while not firing (or not firing well) and the thing was run mostly on 3. Do the rings rotate in their grooves on all the pistons? What does #2 bore look like compared to the rest? Could have been something as simple as a bad spark plug too.

I've not spotted anything noticeably different regards No.2's piston/bore, although I've not looked massively closely yet. The plugs that were in it consisted of three NGKs and one elderly Champion.

I came through Glasgow on the A82, I missed the Erskine Bridge turning, in the BX with a caravan. Didn’t see anything of interest until Outside Edinburgh, when two Cavaliers were spotted on the A720. Wasn’t too far from Annisland.

There was a demo at brands hatch years ago . Two capris were drained of oil and sent out around the track...One had been treated with Slick 50 the other nothing.. One seized up after  half a lap but the Slick 50 car kept going for 20 laps before pitting. Then the shells were inspected, and the treated engine shells were better than new ,  Apparently..;-)

No update for a million years, but now there be this:

Yes, I built a new engine, and by I built an engine I mean I had a man build an engine for me, and that man was @Jikovron

Essentially the bedroom based is entirely rebuild-able for not all the monies and I still fully intend to do such, but it isn't currently practical to do so given my lack of facilities - That is is now going into long term storage (either under my bed or in the basement I'm not supposed to use). Mr @Jikovron saw a 1300fwd motor local to himself for much cheaps and asked if I'd like to purchase it, so I did.

Now, there was some worry about the fwd engine not being compatible with the rwd running gear but we've done a few measurements and comparisons between the engine he has and the ones I have (especially with regards the crankshaft) and have yet to find any evidence that it won't fit, even the dipstick position for rwd cars was still present in the block, just plugged. This engine also has the added bonus of being a pre-rationalisation engine with a better bottom end, so the decision was made to build this one.

Now, I've not been present for the build and @Jikovron has all the details but so far the engine has had a re-bore, new pistons, skimmed head, re-ground crank, new bottom end/small end/main bearings, new thrust washers, new tappets, timing chain and tensioner, new seals and core plugs, oil gallery plugs were removed and the galleries cleaned. The remainder of the work is fitting the Dolomite specific bits and putting it in the car. Needless to say I now owe him a respectable amount of money (although less than either of us thought), and endless gratitude.

Now I just need to get said engine from near Chesterfield to Glasgow. Doesn't need to be any time particularly soon although I'd like to get it in the car come Spring. Anybody travelling this way with a free boot? ;) I'd go down and get it myself but by the time you factor in fuel costs and time it is pretty much cheaper to have is sent by Shiply, not to mention if I took the Acclaim the weight would be a killer. So I figured I'd ask here on he off chance one of you fancy popping by for a cup of tea!

 

TL;DR - I had an engine built that might fit the car I need it for. Anybody want to move it several hundred miles?

That looks excellent. Assuming it fits.....:)

Having had a closer look at the skimmed head, are the corners nearest the camera (circled in red) supposed to curve downwards like that? Could they be a potential leak spot later on?

      Hi all, new to the forum.  Thought you might be interested in what I've got myself into
      I'd been after my first classic car for a while.  If it's big and made in the 70s I'm interested.  Looked at few things like P6s, Zodiacs, Victors, SD1s and various other things.  Problem was I didn't want to spend a boatload of money on something that looked alright but underneath was actually a total heap.  The solution was to buy a complete heap in the first place and spend the money fixing it.
      So in January I went ahead and bought this from a colleague at work who was moving away and needed to get shot of it.

      It's a part finished restoration (I prefer not started) and it needs a whole load of help if it's going to stand any chance of using a road again.
      Pros
      It's right up my street.  Granada Coupes are quite odd and certainly stand out from the norm.
      It still has the original engine, box, interior and most trim.
      It came with loads of panels I need to repair it (mostly original Ford stock).
      It came with so many spares I could probably build a few Granadas and still have stuff left over.
      It was cheap.
      Cons
      Most of the front end has been cut off.
      Most of the body structure is quite rotten.
      It's going to take me ages.
      I work at a restoration company and my boss kindly allows me to keep the car there.  So I've got access to all the gear I need to restore it.  I've been busy on the car for a while now so will post more pics over the coming days.
      Cheers

      Caveat - I have not sealed the deal on this. This could easily go pear-shaped and is utter insanity anyway. However there is a MK12 Invacar for £300 here:

      http://www.wafrost.co.uk/contact-us/



      Could anyone offer transport to me please? This would be to my rented lock-up in Whitstable CT5.

      155 miles.

      Thanks.

      Obviously I would be paying you for this. Preference is to keep in house though given the absurdity!

      UPDATE 1:
       
      As of post #40, the Monte Carlo SS is up and running! For now the project is on hold until May when I get back from college for the summer. Once I get back, I will be continuing work on getting the car road-worthy once more,. This includes getting new tires, cleaning it, getting historic plates, registering it as such, and switching the insurance from "in-Storage". Exciting times lie ahead in the coming months for this classic 80s car
      UPDATE 2:
       
      As of 27 May, 2020, the Monte Carlo SS has left the driveway for the first time in 14+ years. New tires have been fitted and now all that is left is renewing the registration, updating the insurance, and taking care of a few cosmetic issues, then it'll be all set for normal driving once more.
      Original Post:
       
      Hello fellow shitters,
       
      The time has finally come for me to take a look at my dad's 1987 Monte Carlo SS. He bought it brand new back in 1987 and has kept it with him since then. The car has been sitting idle in our garage since I'd estimate 2004/2005/2006? I know the last time It received daily usage was 2003 and then was driven every so often until around 2006. Since then, it's been left to decay in the garage. I began to give it a bit of attention back in December of last year, and I've simply been to busy to look at it otherwise. All 4 tires had long since gone flat, so I filled them back up. The two driver's side tires are still inflated now over a year later, but the passenger side deflated within 48 hours of me filling them. If I recall correctly, at least one of them had a hole back when it was left dormant, which is likely the reason as to why it was left dormant. So its possible its just the tires, or there's now axel rot from it sitting for so long which is why they deflated so quickly.
       
      Besides the tires, the car is covered in about an inch of dust, so that'll have to be cleaned. The upholstery on the roof of the car has come detached and is currently being held up with thumbtacks, although that happened way back in like 2000, so that's been like that for awhile. The battery is stone dead, so that will need replacement. The rubber seals around the doors might have to be replaced since I'm not sure how they would hold up in the rain. Finally, whatever fluids are left are probably long stale or evaporated, so they'll need to be replaced as well.
       
      As for some cosmetic things, the left brake light cover is cracked and has been since again, around 2000. The center console cover is falling apart and probably could use replacement. The car could also use a few touch-ups on the paint as well. Given these are just cosmetic issues, they're not really major issues that I need to address to get it drivable once again.
       
      I'm planning to work on this on Tuesday during my spring break from college. My grandfather, who has been a mechanic for the past 30+ years, will be helping me to get it running once more, so it should be a pretty easy job. I plan to take pictures and to film its first start in over 10 years once the time comes. Really excited to get this car going again since its a fantastic 80s car, with it's maroon interior and exterior. I think my dad will be pretty excited too since he loves that car.
