D2/td5 1999 almost 280k Intermittent, usually happens on an incline or hill, accelerating up hill &have to back off for traffic or speed limit signs, put the foot down again &nothing for 2 3 4 5 seconds with a big cloud grey/blue smoke then everything is fine again. The oil level remains constant with no indication of coolant contamination & the coolant seems free of oil. Does seem to use a bit of coolant but can find no obvious leaks. Other than this occasional problem car idles & runs fine..

any advice would be much appreciated

Unplug your MAF to see it it has any effect as it could be after packing up.

Would first have assumed turbo failure esrpcially as its worst when you put you accelerate but if your sure its not dropping oil, it doesn't sound like it.

Might be best to just pull off the intake pipe anyway though and just check the turbine shaft for play.
