Oil in Coolant (Not the usual)
Hi all, hope someone can help.
This is an old problem but I really want to get it sorted as the oil is slowly melting my coolant hoses.
I have oil in my coolant, lots of it. It's black and floating in a layer 3 inches deep in my expansion tank, not the browny mayo type.
No sign of mayo deposits on the dipstick or on the underside of the filler cap.
The car runs fine...
I have had the head removed and crack tested and rebuilt. No problems there.
I have had the oil cooler replaced. No problem there.
Can anyone think how this oil is getting into the coolant system?
I will need to replace the coolant hoses soon as the oil is eating through them and they will soon burst. I want to find the problem before forking out for new hoses!
Any help gratefully received.
