Well this looks like a good forum, just looking at the first page all the posts have replies! Excellent. Well I've just got my first ever MB, an old W201 C220 estate with what should be a lovely reliable non-turbo diesel in it. Now herein lies the rub. I got it home and the head gasket blew. Ok, well the chap I got it from says 'I'll supply the parts' so ok, but I asked him to get me a genuine or Payen head gasket. He didn't, and got a BGA set which if I'm honest, looked rubbish from the outset. Actually cut my hand quite badly just getting the exhaust gasket out of the packet! I've had the head skimmed and examined (but not pressure tested, that's impossible in Ibiza.) Well anyway, the first day after repairing it all she started leaking oil out the back of the gasket. 50km later she blew all the water out and is failing my CO2 test. So here's the actual question: Head gasket again, caused by it being rubbish and oil contamination, or cracked Head? Thanks! Owain.
