Not unknown tbh.

These are what it has in it currently. 

Will inspect and assess, he's driving in it atm so if it fully dies I'll know. The only spark plugs I have lying around are a totally different tip type to that one.

I'm also really not convinced their not fake shit spark plugs though 😂

You don’t need iridium plugs on that. A set of NGK standard ones will be fine. 

[beko1987]

Awesome, thanks!

(is it the 2l ecoboost he has? From googling it seems to be)

I've got these that were destined for a mates Mazda5 petrol a few years ago but never made it before the car got fucked off for natural reasons so if I can use those incase we remove the plug and it's fucked then that works 👌

My friend came over just now and thankfully it seemed a simple fix! No4 plug was bloody loose 😂

However when we popped it out, 2 of the threads had crap in, I guess where it's been vibrating against itself for ages 

We changed the lot as I didn't want one to be sparking differently to the rest, the no2 plug was very oily, the other 3 dry... Does that mean anything?

They've been in since early March.

I did take a photo of a connector coming off a sensor covered in oil too but the Pic didn't save... From an internet image it's this connector here. What is this thing? The oil looks to be coming up from the connector itself

Back from a continental trip to Berlin, Salzburg, Köln and Amsterdam. The 2.0 TDCI performed perfectly, returning 46 MPG (brim to brim) over 2,500 miles despite quite brisk motoring. 

It will be treated to new engine mounts and new front brake disks as a token of appreciation.

PAS sensor to increase idle when steering turned.

Thanks!

I shall do some googling and see if it'd worth doing anything about for him/fire some brake clean over it all and clean it up and check in a few months. Zero wrong with the steering currently

I’d leave it well alone. More likely a problem will be shagged out PAS fluid that goes black when the rack seals deteriorate. Worth changing for some fresh CHF.

I've not got round to the engine oil change it wants yet, let alone fancy stuff like that 😂

I put an offer in on this this afternoon. Now waiting to hear if it's been accepted.

A 1.6 Titanium.

Edit:- It turned out after a car check that's it's been owned by a garage since before Christmas, and wasn't being sold on behalf of a "friend" who didn't like dealing with the public. Shame, it was a nice thing to drive. If the guy had been upfront I would have bought it, although I would have tried for a lower price.

The backbox on my mates mondeo is trying to escape!

I'm going to find some unsuitable wire and affect an emergency repair hopefully tomorrow/Tuesday but are the trustworthy* ebay diagrams correct and something like this is the right backbox? (petrol car)

And if we do change the backbox, how much of an arse might that sleeve joint be? (if anyone knows the right part number for the backbox I'll be happy to search with decent info rather than the ebay "it fits*" system 

[beko1987]

My friend came over this morning when his missus got home from work!

He's bought a big roll of wire from screw fix at my direction and in hindsight it was a bit too thick but it did the job! 3 loops around the backbox itself

Then we realised there was buggar all to actually hang it from! So the mess around the tailpipe got us to the right height, then I looped from the top of the backbox forward and up to the only rear hanger

Its nice and solid and doesn't hit anything. Hopefully enough to present it for a test and see if it's worth changing the backbox. It's the original I think, there's no cut on the pipe leading to the centre silencer which the pattern parts have a flange at.

Main job done, we figured out why the rear parking sensors are a bit shit, one has a broken wire!

Can I cut and solder normal random wire to this to fix?

To the immediate left of that was a broken plastic bumper bracket, which was making the whole rear bumper very loose. We fixed that too

The cars had a biff at the back at some point but only this bolt on part is creaked, and it looks very historic. Probably why the bonnet corners are a bit shit too

Two final jobs, one was sorting the stop light error on the dash, that didn't take long to troubleshoot

Wafted it over the wire wheel and fitted a new bulb and the light went off

 

2 cable ties and 3 trim clips about the rear arches finished the jobs off! Underneath is very clean

Wish my qq was that clean 😂

He has however just WhatsApped me, he's got the condensation filled front headlight off to get an air blower in there and found the connector looking a bit peaky

The headlight still works, I've advised wd40 or get some contact cleaner and we get a headlight AND that bit of the loom and Ill solder it together

[warren t claim]

The headlight connectors do get like that. I've seen worse ones still working.

He went and got a tin of contact cleaner and dried it out, then I told him to smear Vaseline around the connector to help it seal and get it booked for a test whilst it does work 😂

I had to weld the hangers back onto my exhaust too.

That's pretty much all it needs, now I've looked closely at the system it's perfectly fine otherwise.

He's got his mot pretty soon so he's gonna ask the garage he takes it to if they can do anything, just an bit of metal snotted on would do. Hopefully the exhaust held on by wire will emit some sympathy (assuming it's a clean test otherwise)

Have found these things but I need to check they might line up first https://ebay.us/m/Blyfo9

I am currently spending an extended amount of time underneath my wife’s Volvo V70 P3. The underneath of one of these is near on identical to the Mondeo! 
im starting to realise there is nothing Volvo about our Volvo

The mondeo's windscreen washers just dribble. I thought I would have a look.

The panel under the bumper has to be pulled. The screws were like coconut tobacco and some were seized.

I pulled the pump. The filter screen was clean - the bottle equally so. I put compressed air into the pipes.

I noticed the mounting for the radiator was very rusty - I gave it a clean and some satin black.

Put it back together. Unfortunately there has only been a slight improvement- the rear washer is fine. It might just get through the MOT - I cannot be bothered replacing jets and pipework - car has done 145k and is nearly thirteen years old. Given how ratty it is starting to look on the underside I wouldn't expect it last more than a few years.

[Low ontime]

Coffee machine de-scaler tablet may help if you live in a hard water area.

youd need take the jets off the car and submerge in a tub.
