Oil in the coolant

[P. A.]

Thanks for the feedback. I'm afraid the head is coming off then. The last
time the head was off was 60K ago w/ a full bottom/top end rebuild. Decked
the head, Raceware head studs, new coolant etc. And since the turbo is
working fine I guess the head gasket remains the likely culprit.
Thanks,
Patrick
