1997 850 Oil in flametrap

Post by cem351 »

I replaced the pcv system on my 850 last fall and this wknd while putting on a new throttle body gasket I saw some oil (as in a few drops) in the flametrap when I undid it from the lower elbow. Also some in the elbow itself. Not a lot just a few drops worth but it doesnt seem rite to me. is this normal? All vacuum lines are good,engine not smoking and mileage is decent (26 mpg) or so.

The only thing abnormal about that is that there is only a few drops. The oil vapor (which is what the PCV is trying to burn) tends to condense at the flame trap and typically it is filthy. Particularly in the winter where it tends to actually clog from a mixture of water vapor and oil vapor. It turns to a gooey mess which is why most of us just take the flame trap out and throw it away.
