Performer Install: one more prob.

SM0k3 · Sep 30, 2005

well after figuing out i didnt have a vac leak and the car was running like crap because i crossed wires 3 & 4 like a dumbass, I ran in another problem.

I didnt use those cork gaskets on the intake because a lot of peeps(including the FAQ) suggested not to use em and just lay a thick bead of RTV......well I did that and im getting a oil leak on the back passenger side of the intake, im wondering if theres a way i can seal up that hole without pulling the whole damn thing apart again?

RTV ROCKS!

Just try to clean the area real good with brake clean, cut off the excess RTV and try to squeeze some more back under the intake to fill in the gap. Might want to put some on your finger and line the whole back area where the intake meets the block.

I have been using those cork end gaskets for over 30 years and have never had one prob with them leaking.

What I do is use 3M weather stripping glue to stick them on the block.

I know everybody says they suck but they work just fine for me with that method.

What ever works for ya ... I guess

I suggest removing the intake and clean the area good. Then re-seal with RTV. Alot of ppl don't like to use the cork b/c it moves when putting intake on top of it. Grady's suggestion may work to keep it in place.

Before I pull the intake I would go the clean it and try either some RTV or silicone to seal it. Then if it still leaks pull it and re-do it...

In the Fel pro intake gasket kit, it has 2 rubber ones for the front/rear of the block. They work great, and I always put a small bead across them.

That is a big gap to cover w/ RTV, so I would recommend using the rubber ones to take up the slack.

A agree...

I just got done redoing my intake because it leaked and i didnt use the cork. I redid it with the Fel-Pro gaskets that have the rubber ones, leak free now!

That is the only way I will install the intake gasket. Puta bead of weather strip adhesive onthe bottom, place it on the block, let it sit for a while to dry, put a dab of RTV in the corners where the rubber (or cork) gaskets meet with the intake gaskets, install intake. Worked every single time I've done it

I went and felt around the hole and i think i just didnt use enough RTV on the end but it didnt feel like it was a big hole so im gonna try and sqeeze a little bit more RTV in there and see if that stops it.

I would love to see if you figure this one out. I have a similar problem w/ my performer rpm II. Except mine was due to a pinchd pcv hose that buil up pressure in the crankcase and blew out the rear seal. I've been too lazy to fix mine so I jus end up adding some oil very few weeks. But yea I havent tried to slather anything back there either. You could try that and maybe it will work. It sucks to have to take off the whole manifold and spend another $20-30 on a new intake gasket. I say try the rtv in the back with your finger if you can get back there. If that does not work then you will have to take it off. However the first solution is just a bandaid. Really both of us should take our lowers off and redo. I'm just too busy and lazy. Good Luck...but dont be surprised of you have to take it off again. Or you can just live with it like me.

Screw a long stud in each corner and then the intake can't move during installation cause ........................

the studs make you drop it down nice and straight

Hey final thats a good idea (using the studs). Actually when I installed the first time I used the cork and it squeezed out during torquing probably (cuz the cork moved when I put the lower on at a slight angle) and I got pissed since I lost $30 on the intake gasket. Next time I used a TON of RTV and that worked until the PCV issue blew it out. At that point I was tired of taking the manifold off so I said F**k IT and I have been adding oil ever since. Maybe I will try putting more RTV on the back before I go to gingerman...hmmm. But yea next time I take it off I am going to the hardware store and getting some long studs to get it into place right the first time.

i used this method too when installing the lower, works great

also ive never used the cork/rubber pieces, always used a thick bead of RTV and never had a problem

I see you are in the fine state of Il

Don't know about yankee land, but here in the GREAT state of Texas, we got some stuff I call "all thread"

It is just a rod about 3 feet long and it has threads all the way up and down the rod.

Works great for this application and it is really cheap
