oil leak

[Itkix]

Just put on a u/l Trickflow intake, and a blower at 10 pounds boost have ran several times with no leaks until today I looked on the floor and at the back of the motor had a small puddle of oil on the floor, so I'm asking if the rear of the lower intake leaked would it leak oil or would it be water thats wear it appears to be coming from.

Take off the intake and see.

do you have breather cap(s) on your valve covers. if you arent venting that pressure, that pressure from the blower might have blown your rear main seal. just a possibility

Do have oil breather cap, and the oil is in a puddle on top of the transmission and running down.

Yes, oil can leak from the rear of the lower intake. I had an identical issue myself after my rebuild.

The PCV valve is at the rear of the intake... could be blowing out of there. Have you replaced the PCV valve AND the little screen assembly under it??

Oil being on TOP of the tranny makes me think it's not the rear main.

Could just be the intake seal didn't take as well...


clean it up back there, fire it up and feel around until you can find it...

I thought it might be the Pcv but no oil running down from it, I'm gonna half to tear it all apart and do it again,always something. Guess silicone didn't seal or blower blew it out, well at least it wasn't a head gasket or I dont think.

I'm getting ready to pull the intake off and put it on again, do you guys use the gaskets at the front/back of lower intake or just silicone, I used only silicone last time,thick bead, I don't wan't to do this again. Or maybe the blower just caused the leak from the pressure?

i use the gaskets and silicone. but before placing the intake on the heads, i put a good gob of silicone in each corners of the front and rear of the intake so it can seal good
