Oil behind throttle body
Oil behind throttle body Hey guys, having an odd issue and hoping I can get some help. Setup is as followed:
LS6 Intake Manifold
LS6 Valley Cover
Vent hose from passenger valve cover to throttle body
PCV hose from valley cover to intake manifold with inline PCV valve
I pulled off my intake elbow today in anticipation of porting my throttle body and the first thing I noticed was a little bit of oil on the bottom of the butterfly blade. Pull off the throttle body and there is a sizable pool of oil in the bottom of the intake manifold (rear of car is in the air right now, so I'm assuming it all came forward which is why I haven't seen it before).
Motor is fresh rebuild, has roughly 2k miles on it right now. Been driving strong, no issues, no evidence that it has been burning oil.
Just wanted to know 1) is this normal and 2) is there anything I can do to prevent it. I am assuming the answer to #2 would be a catch can.

I was just doing a deep search on this Friday lol. The ebay ones don't really do much since the cans are bascially just an empty can. There are a number of different companies that make reliable ones or you can make one yourself, depending on your budget. Do a search on Catch Can and one thread in particular should answer all your questions, it's like 30 pages long!

For $20 + ~$10 for a few parts to baffle vs $200, can't complain.

I was looking at doing that too, which one did you go with and where are you planning on mounting it? The P.O. removed the A/C, so I'd like to find one that fits in the bracket where the accumulator used to go.

As for where I plan to mount it, I wish I could help you with that but my LS is actually a swap into an S2000, so our locations would be completely different, lol.
