Forum rules


When you put a new thread up in the Workshop please put your car's year and model in the thread title, along with just a brief indicator of the problem.

Car Year - Car Model: Brief description of issue. EXAMPLE- 1999 9-3. Problems starting when hot.

Please also add as much information as you can about the problem, to your post.

This will help us to help you, without having to ask basic details such as what car you have.


Threads with non-compliant titles will be moved to The Pit Lane (in which no replies can be posted, but the OP can edit the thread - upon which the thread will be released to the workshop forum)

Nb. Generic thread titles for truly generic issues that genuinely are not model or variant specific (such as "how do I change the spring in an forge wastegate actuator") are acceptable

**The first 5 posts for new users require individual moderator approval (which they will only get it if they are in line the rules of the forum). Please be patient and allow time for that to happen, and avoid duplicate postings.**

So, what to do? Like the car and all good at present but what might i consider at this mileage for a keeper. Is it worth considering new bearing shells, oil pump and chains? Which bearings wear most - big end or main and can the mains be changed whilst the engine is in the car - just thinking out loud to prevent a major before it happens. I guess I could also fit an oil pressure gauge to see what is happening to pressure hot and cold? I imagine also a new core for the turbo wouldn't go amiss. I do have a spare engine (234 I think - need to check engine number) and a spare 5 speed auto box with low miles on. Could build up the spare unit with box but would need to rob some parts off the existing unit to build a hybrid and I am getting a bit long in the tooth for this malarkey. :shock:

For me personally I would just do scheduled maintenance and look into anything that shows signs of developing into a problem.

If you like tinkering though..........

so would I, plus a compression test and keep an eye on the emission readings at MOT time.

In your position I think I'd take my time and rebuild the spare to a full engine ready to drop in, leaving the existing engine alone. Seals, bearings, timing gear, oil pump, the lot.

Then when complete I'd drop the new unit in, complete with massive turbo and fueling to support it :)
Good for another 200k then.

I may be speaking too soon, but my oil consumption seems to have reduced since the new turbo went in.

So, if you are using a bit of oil, check for play in the turbo spindle/bearings. A new turbo now would save the hassle of stripping the inlet and exhaust and cleaning out all the excess oil.

Mine (2005 model year, circa 140k mileage) was using about 1.5 litres every 1,000 miles ... turned out to be valve stem seals allowing oil into the cylinders, most of which was burning off - but some managed to gum up the oil control rings on one of the cylinders (number 3, if I remember right).

Whilst the engine and gearbox were out, I asked the garage to replace the bearings - turned out one of the mains was worn, so it was worth doing. They're not expensive - and I believe they (and the big ends) can be done with the engine in situ, so it might be worth considering getting those done ... ???

In respect of the turbo, if there is play and you're considering replacement - just get a core, I bought a melett one for my previous 9-5, cost about £150 from what I remember ...
