I have seen a film of sludge in the expansion tank before and after head
gasket replacement. This maybe residual and now that you have driven it and
really had a chance to get the sytem hot.

Subject: oil in coolant

just picked up a  parts rig last week.
i had no intention on using the motor, just the interior.
i flushed the coolant and changed the oil just to keep it all fresh.
all was fine until one hour highway drive.
slight skim of oil in coolant expansion tank.
heads were resealed recently and gaskets are plyable and black sealant
evident around both in even pattern.
i assume this is the oil cooler or internal head gasket failure.
any other possibilities?
no biggie, the interior is sweet and the price was right.
