Ive replaced the PCV system on my 1997 850 maybe 6 months ago. today I took off the throttle body to put on a new gasket and found oil in the flametrap when I disconnected it. Also some in the lower elbow that goes to the TB. It wasnt what I would call alot but enough to where I had to wipe it out. Is this normal? Doesnt seem quite rite to me.
