Hey everyone. Got a bit of an issue, I bought a focus st225 blind basically, had it transported to me with what was suppose to be a head gasket problem, I took the head to the engineers and the head was really out of shape. Had it skimmed and refitted it. Started up and after a few mins white and grey smoke seem to be pouring out the back. So it was decided that the head needed to come off again, took it back to the shop and they vacuum tested it and two chambers were really low, so all valves were cut and reseated, new stem seals, all good with the head now, while the head was off I had new rings put on the pistons, piece of mind. Everything put back and it was still smoking, not as bad admittedly, so I looked at the turbo, it was removed and there was play in the turbo, and there was quite a bit of oil in the boost pipes, so I bought a recon turbo, put that on, and it still chuffs out a greyish cloud not all the time but it is bleddy irritating. The annoying thing is the car drives really well now, boosts well and pulls through the gears nice, does anyone have any info or thoughts of what it could be? Pulling my hair out here.
Thanks

 

Have you had all the pipes/intercooler cleaned out if they had oil in them?

 

I haven’t cleaned the intercooler yet. Pipes are clean though. Is there a possibility that the inlet could hold oil? And is it a case of just wait and see if it burns off?

 

Personally, I'd get a leak down test done to make sure nothing is passing the rings first.

When the oil seals go in a turbo it is suprising how much oil will end up in all the pipework plus the intercooler. I recently put a brand new turbo on my Son's Subaru Impreza and before it was fitted had to really clean all the pipes and the intercooler which all had bad oil contamination.

 

Also if there is water in the exhaust it takes a while for it to get burnt off.

funny you say that. I was thinking along those lines, I took the aftermarket back box off and stood it up on it edge and there was water dripping out of it for ages. I have obviously since put it back on, doubt I got all of it out. I wonder if it’s worth sticking my standard system on it.
