intake manifold gasket....please help! I have a 99 ls1 camaro and I'm pretty sure the back of the intake manifold is leaking oil but I'm having issues on what I need. I see the felpro gasket set that looks like intake runner rubber seals and I see a felpro litter valley gasket set but it doesn't have a picture so I don't exactly know what it looks like. Like I said it looks like its leaking from the back of the intake so what exactly do I need to buy/replace? And is there anything else that might be leaking while I'm back there, I've already done the rear main cover gasket, rear main seal and oil pan gasket. Thanks
Is your oil pressure switch or cam sensor leaking? They are behind the intake, and is the only thing with oil. The manifold is dry, so the only oil youll find in it, is from the crappy PCV system.
Not quite.. The valley cover uses the seal you are talking about, in the Felpro set..

I'm not too sure if those sensors are leaking I just took a quick glance and saw oil up there so I assumed it was the intake manifold. So what should I replace then, just the litter valley gasket? Should I do the sensors too just to be safe?

Bro....WHERE exactly do you see oil?
Inside the intake?
Or on the exterior of the intake near the back of the intake?
If you see oil inside the intake, its coming from the PCV system....go get a new PCV valve....$3.00
If its oil on the outside of the intake.....its coming from the OPSU or the Cam sensor.
Intake gaskets only seal "air", they have nothing to do with oil.
***If it turns out to be the Cam sensor......I have a brand new AC Delco one in the box.......$50.00 shipped. Paypal.
