Sealing oil pan...

Ok.. I need to re-seal the oil pan in my girlfriend's Shelby Charger, it's leaking profusely. I need to do it with the engine and tranny still fully installed in the car. Seems like this is possible, anyone actually done it that way? I plan to remove it, clean all the dripping oil up so that I can get some clean surfaces, and then put it back togehter.. Now for the other half of my question.. What to use to seal it properly.. I've read that Chrysler doesn't specify a gasket for that surface, that they just say to use some sealant.. Is that true? Can I get a gasket for that surface? Every other car I've put together has used a gasket there. I've used an anaerobic sealant with great success on oil pan gaskets in the past, but I've also been told that it's the wrong sealant to use.. heh.. So I'm open to some clarification here..

Yes I've done it in the car before -- but it was on a Daytona, but I don't think you'll have any interference issues; being on a Charger.

I used black RTV on mine with the rubber end seals, I didn't use the cork gaskets that came with them. No leaks so far!

Using a bead of silicone will work fine. You need to give it 10 minutes or so to set up before installing the pan. When you can just barely touch it and it doesn't stick to your finger its ready. The best stuff i've found for that is the grey sealant you get at the Ford dealer. It originally came out for use on the diesels. Very good stuff for a bead type gasket. Comes in a caulking tube.

The grey Ford RTV is a very, very similar product to Permatex's 'The Right Stuff'. Great sealant. Ask supercrackerbox what he thinks about the ford stuff. I used it to seal the oil pan on his GLHS. he had to remove the pan a few months later for an unrelated problem and there were no leaks or any signs of leakage. I use The Right Stuff or the Ford RTV on everything I can that requires some sort of RTV.

All you have to do is remove the 3 bolts that hold the small bracket on the backside of the motor. This helps with clearance for installation. THen remove the tin/metal splashguard that keeps crap out of the tranny by pulling a couple more bolts. Then just drop the pan. Clean up the pan, and block. Buy the two end strips of rubber gasket from chrysler and silicone the rest. Good luck.

I'm having trouble with the end nearest the transmission. Seaps out big time. I tried with and without the cork side gaskets. Also used the RTV High temp black (kinda greyish) silicone and it still leaks. Weird cause it held for the first 18k after the rebuild and now this. Any more Ideas?

Do NOT allow RTV to "skinover" before installation. it will effect sealing.

Additionally a 1/8" bead is all you need. stay toward the inside of the bolt holes. Do not go overboard on use. a little is good, a lot is very BAD. I've had to rebuild 3 engines that people have gobbed the RTV which plugged the oil pickup screen and smoked the bottom end.

Man, this is an old thread.. I used Napa's "The Right Stuff", and it sealed PERFECTLY.. Still holding to this day.

Haha, digging deep tonight weren't you Una...

Hey.. I'm not the one that pulled this thread from the Crypt.. heh.. Someone else pulled it up.. and I guess it is proper forum etiquette to do a search and find a thread that was already going rather than starting a new one.. heh..

I tried that stuff for the first time this summer. Looks like RTV, smells like RTV, applies like RTV. When it cures, it's not nearly as soft as RTV and cleans up much easier. That alone makes it worth the money to me.

Cool, I'll look for that stuff...
