oil in intake

[blk92]

I have oil in the upper intake and i installed the baffle on the lower and put a new pcv valve. What could be causing oil to build up in the upper intake manifold? And how can it be fixed. thanks

Part of the problem is blowby. To much pressure in the crankcase pushing oil up in the intake. You could but a catch can between the PCV and intake, I've never done this but many have, seems to work for them.

90GT is right on. i will just add that it is really normal (as 90GT said). a catch can and filter are the way to go if it bothers you.
