I'm wondering if my current white smoke is from a slow build-up of oil in the intercooler that only gets blown out with the occasional use of a heavy right foot rather than directly from a turbo at the time.

There's always some compression blow-by and even though most of the oil is condensed back to the sump, some oil gets through to the intake tract. MY12 RRV 4.

Mine's had the drain pipe upgrade and I'm monitoring the situation. Got up to temp and suddenly the system pressurises and chucks some water out the exhaust, is this classic inlet manifold gasket symtoms or cracked head? Stripping it down soon but was hoping for some good news, preferably just the gasket gone. V8 cylinders are numbered even on one bank and odd on the other. Well if you've got problems with opposing cylinders from each bank it would seem likely to be the inlet manifold- it attaches to both sides.

Either that or you have two head gaskets gone and you have just had the bad luck equivalent of winning the lottery. I mean, what are the chances?? I guess you could check compression on those cylinders in reference to the other "normal" ones as inlet manifold would not affect it like head failure would?

I may be wrong on this though Stripped her down and the inlet was fine so started on the heads. It has pitted the block by the liner, do you think it will be fine filled in or would it upset the fine tolerences of a rover v8? You can post now and register later.
