hi guys you may have seen my post over the weekend about possible turbo failiure,

well tonight i have done compression test and passenger front cylinder 0 on the reader the other 3 have 146psi
their were no knocking noises from the bottom end, is it less hassle to just buy recon engine or bottom end, or strip and look at putting rings in it? if so can anybody recommend suppliers for the bits.


thanks again

 

Sorry to hear that, had the feeling it'd be something like this when reading your original post.

It's unfortunately impossible to accurately answer your follow-on question about which option will provide the least hassle without stripping your existing engine and surveying the damage.

Even if it isn't that bad, rings don't generally fail by themselves, compression loss is almost always secondary to a ring land, crown or skirt compromise. If you've literally got no compression at all in the no. 2 then that points to a complete piston failure with probable secondary bore damage.

If that's the case, and depending on the age of the car, a complete replacement may be the "lower hassle" option - but again this is just an educated guess. The other point worth mentioning is that if you have suffered this sort of failure, you ideally need to trace the root cause of it before fitting a replacement otherwise you run the risk of repeating it. You really need someone to have a look and listen to your car before making a decision on the next step.

Also - a minor point, but when seeking help with one problem, can you try and confine things to a single thread? Spreading them across at least three, as you've done, makes it difficult for anyone trying to help you to get the full picture, which in turn reduces the quality of the help you'll get.

 

SPLITPIN Thanks for your advise its much appriciated.
