Oil leak, rear lower intake.

Sure it's not a valve cover leak?

Cleaned with brake cleaner and a razor. :/

Can I shove some rtv in there? Or will that just leak too?

Fml god damn 1250s3s are not cheap

[ktm300hater]

clean and dry before you put it on? And your sure you didnt move it?

[91CoupeMike]

use RTV on the front and rear where the intake meets the block, no gaskets.

That is what I did, I guess I didn't use enough?


I put like a 3/8th bead along the ridge of the block and dropped it straight on.

Ding dong moment, at wot there is no vacuum, so that would explain the crankcase pressure.

Open to any and all suggestions!

Okay, so after installing the lower intake 2 times I still have an oil leak.

Anything I can do without pulling the intake off again? :/

I just went out and beat on it and I had some smoke at wot and through the shifter at idle.

Popped the hood, and noticed it going down the passenger side of the block and getting on the header, causing the smoke.

Shouldn't the pcv valve pull vacuum to keep crank case pressure down? I'm assuming at higher engine rpm it blowing out of the back of the intake.
