    Car has started to smoke under idle much heavier now! The car only smokes when it has been sitting for 1min+ and is much worse when starting on a hill or the car is fully loaded.

    Apart from this the car does not smoke at all, no start-up smoke, WOT...ect and has an almost new K04 turbo.

    It does have quite a large amount of blow-by with blue smoke through the oil cap too, I found this post below while searching, no replies unfortunately.


    I am fairly sure that this is the piston rings as I have been told this before but this PCV valve has got me thinking - do I really need an engine rebuild after all? Is there any way to really pinpoint this oil leak?

    Thanks for any help!

    Was it a genuine Borg Warner turbo?

    I would look at the one way valve under the inlet manifold, that could maybe cause high crankcase pressures if it's gummed up

    I will have a look at the valve, maybe it is worth replacing to see if it makes a difference. the car always seems to smell like it is running too rich also.

    Its an RP turbo, apparently they are pretty good, been on the car for over a year now without any problems. it was smoking before the new turbo was fitted so dont think that its the problem.
