These engines run cool rocker covers, in cool weather you get condensation causing the yellow foam in the oil filler. Nothing to worry about and not enough to make you change the head gasket unless you have other symptoms.Does anyone have a Head Gasket DIY ?
Im thinking my Daughters Beetle is going to be needing one soon,
I changed the oil today 142,000 miles, noticed yellowish foam on the oil cap...Im guessing the head gasket is leaking ??
Any ideas ?
What kind of oil are you running in the engine? Might not be a bad idea to change it to a VW 502/505 spec oil like Mobil One 0W40 or Castrol 5W40. I heard Castrol 0W30 also has the 502/505 specs. Don't run cheap oil in your VW engine. They are prone to sludge especially the 1.8 engine.That sounds like good news
The car is not losing antifreeze, and everything looks good
No bad hoses, vac lines etc. , car runs great
