Oil Heat Exchanger - 147 Oil Leak
I have alot of oil located around the oil filter of my alfa. It is absolutley everywhere and has also seaped into the cambelt enclosure area which i would prefer not to have, as hydrocarbons and rubbery materials donot mix (especially as i am fitting a new cambelt). I have looked around on numerous forum pages and sites and have become disheartened as no specific information except by a new heat exchanger.
I have subject the excanger to a low air pressure test and submerge in water with the result of no air bubbles present.
Is it known that the link between the engine block to heat exchanger adapter is not entirely oil tight?
Also, if i by pass the heat exchanger how would this effect the car and temperature. Has anyone done this before and if so could you tell me the effects this has had.
