Ok, so after a total of 8 or so hours we have managed to change the nearside turbo on my Z. For the passed 2 years or so it had been smoking on tickover (worse when warm).

 

Touch wood, so far, it seems to be a lot better. I have left it running for well over ten minutes whilst the engine is hot several times and nothing yet. However, last night when the car was cold about 2 miles from home I pulled up to a set of lights and there it was, some smoke from the exhaust. When it was safe to pull over i did and let it tickover once again to confirm if it was the same side, but nothing. It wouldnt smoke for the rest of the night...

 

It definatly seems better but am concerned a little about the smoke I have seen. Is it possible it is burning off crap that has settled in the exhaust from the old turbo, or is this wishful thinking?

 

Also, when I started it in the garage this evening, both exhausts spat oil (I think, could be fuel though) out. The nearside worse than the offside though. Are these signs of a worn turbo?

 

Either way its on now for at least this summer but just like to know your thoughts.

 

Thanks, Dan

It will take a while to burn old oil from intercoolers, pipe work and even oil in the exhaust..

So fingers crossed shes ok..

Could it be a problem with the pcv valve on that side?

Hope so, I replaced the PCVs last year hoping this would of sorted the problem, it didnt :(. Whilst everything was apart I gave the nearside one a shake and sure enough it rattled so I put it all back together.
