Catch can fan got butter!ilk ea81. Puzzled


Recommended Posts

Pretty good idea the catch can on the pcv system. Mine is sort of different. A filter is on the rhs rocker cover and catch can feeds from lbs and vapours go to the air filter. I can see my 18 mth old alloy radiator losing water, but also getting baby poop colored buttermilk slop in the catch can and draining it before it gets to air filter.

OK now oil in water or vice versa and got brass freeze plugs in heads

Runs like a dream. Never found this unique problem before. 120,000 km since full rebuild ten years ago. Has to be head gasket surely? I do also have coolant going through gas converter for propane. Four days before runs out of rego. Time to investigate after then!
