Think of a green curry/baby poo mix, now put it in the expansion tank of my Cav Gsi.
No signs of oil/water mix in the head (no mayonaisse). Car is running absolutely fine, not overheating or anything. Expansion take has a slight smell of exhaust fumes and petrol.
Suggestions so far include; Head Gasket, Oil cooler, Heater matrix, and in need of a good service!
Last 2 have been done and the problem still persists.
Have flushed the system 4 times in past 2 weeks, ran the hosepipe straight through the radiator, then the matrix inlet and outlet. Went to vaux to get an oil cooler (£220 so i thought i'd leave it for now)
What do you think - Head gasket??
