Just got home in a cloud of smoke again : (
This is now 2 months after starting this thread. It happened the initial time, and my partner said it happened once to her (but i could get no diagnostics) - now its happened one more time when ive been about.
The smoke is coming from the exhaust. Billowing out. I think the video i took was a complete red-herring. This is thick, and smells of burning tyers (ie certain oil and not fuel). Its white, not black.
Came on after going up a hill here that's called 'long drag' - ie long, not especially steep. Busses always get stuck on it when it snows.
Was going 50 ish, at about 2500rpm. Smoke came on when i took the engine off load.
Engine stayed smoking, to greater or lesser degrees, all the way home (sometimes pumping out, somtimes almost clear)
To recap -
Unlikely to be rings, right? Starts fine. Would also not be intermittent like this?
Unlikely to be stem seals?
Not the seals on the inlet side of the turbo, as there's no oil in the hoses.
So, its got to be either turbo exhaust seal, or, could it be head gasket? Do these ever leak oil into the combustion chamber?
Now that ive 100% confirmed that the smoke is coming from the exhaust (and not external to the engine) its time to start changing parts.
