This is on my funky 95 VVIS non-turbo 850.
I bought an all inclusive kit from IPD (they were great BTW), and of course I have left over parts, but flame trap connecting piece has got me thinking.
The socket in the intake elbow where the flame trap connects:
1: is it supposed to be removable? I couldn't get mine out
2: I am noticing I still have smoke coming out of the oil filler, and dipstick, I know this can still occur when there is a lot of "build up" in the engine. It seems to me that this little pencil sized hole is the choke point in the system. The tinkerer in me wants to bore out the hole so that the engine can suck more fumes in. I am also still getting oil leaking from the oil cap, which makes me think that crankcase/head is still pressurized.
3: I cleaned the old port and there are no oil leaks coming from it and the flame trap seems very snug in there. Is my PCV system simply not generating enough vacuum to clean all the fumes up/am i making more than normal/am I being a crazy person? hahaha

I do need to get my oil changed this weekend. I wonder if that will help.
