Discovered oil in the water in the past few weeks.
Thought id put up this post to try and get opinions on possible causes and what to check 1st.
Symptoms;
Oil in water
Sludge building on the expansion bottle cap
No rapid loss of oil
No rapid loss of water
No temp deviations from normal
No evidence of water in the oil
My thoughts on possible causes;
1 - Leaking oil sandwich plate
2 - Headgasket
3 - Cracked block between oil and water galleries.
4 - Boost lifting the head (td04 30+ psi)
Going to give the cooling system a flush out to see how quickly the oil returns.
Any thoughts please add.
Thanks,
Anton
PS - Should have added the headgasket was done about 30k miles ago as the car was pressurising the cooling system.
Head was skimmed and a new Payen gasket and headstuds fitted. This was before the td04.
