The goop still looks like condensation from not getting the engine warm......now if he has bad looking fuel lines that would be another problem. The heated breather hose was on the USA 78-79 USA cars ONLY and was expensive and now no longer made. That long hose back to the intake sloped upwards and it COULD act like a still causing water vapors to condense in cold weather and drip back into the oil so they added a heater line to run coolant through a pipe to warm the hose more quickly. The 1980 -1984 they just used a short hose shaped like this ? and dump straight into the lower intake . Allen sees a bit of condenation and suddenly we have speculation about Head Gaskets and the car is about to burst in flames ...... Those hoses have been on there for 24 years ,or 8760 days ;that is 21,024 hours ; or 1,261,440 minutes how likely are they to let go NOW just because someone noticed that they were cracking ? Should they be changed ? probably. Unless the oil NEEDED to be changed for OTHER reasons that need not have been done.

Hi Allen,
Have to agree with Jim. I get the same problem on my car during the winter here in Scotland. I have a drive of 7 miles to work every day and get the same build up of "cream" over a week. A good long drive at the weekend sees the end of the problem.

This is a common issue with the well closed air circuits oon modern engines. Check your engine breather lines, and make sure none are clogged. After that run the car for at least 40 minutes at least once per week to boil off the water from the engine and the entrained water in the oil. The oil needs to get above 225F for the water to be extracted. One problem with the modern syn oils is that they run cooler in most all cases. It needs to get plenty warm for a while to get that stuff out of there.
