JEGS reuseable big block oil pan gasket with windage tray

[resq302]

Has anyone else encountered a problem with the JEGS big block windage tray that has the reuseable gaskets on it leaking at the rear of the engine? I've installed one of these on my charger and it seems to be leaking in the area where the recessed holes would be for the rear main seal. Jegs says they have had no complaints and that they see no way that it could possibly leak. I am just curious if anyone else has experienced this issue as well.

I read somewhere when I was considering one f these,that they aren't to be used on pans with those . Only flat lipped pans?

I don't run cork oil pan gaskets any longer. I simply glue the pan on like the imports. No trouble yet.

Ditto.... dry as a bone since 2000.....

Glue -- Are you referring to an RTV type sealant?

I used ford motorcraft 7.3 diesel silicone. Its the greatest stuff ever made. The entire 7.3 is sealed with it. Oil, gas, diesel fuel, gear oil, heat..... nothing matters and the stuff is thick. Only drawback is its VERY difficult to break the seal once cured.

Maybe I should encase my transmission in that stuff, it's so messy I can't even tell where the leak(s) originate.

yep. Sorry.

No problem, just wanted to make sure I shouldn't go out and get a big tube of PL400 sub-floor adhesive.

Well, I thought I had the issue licked.  It sat for a few days and no leak.  Now, its leaking again after coming home from a car show this weekend.  Looks like the thign is going back to Jegs.  What would make the RTV difficult is that the car has a windage tray and you have to slip the windage tray over / around the pick up tube and screen.  I'll probably order two cork/rubber gaskets from the local auto parts store and just coat them with the Indian Head gasket compound and hopefully that will seal it up.  Only down fall is it is harder than hell to get that stuff off once its on.

Are the bolts still snug? If it was fine sitting but leaked after run then it's got to be heat expansion/contraction that is allowing seepage. Is the pan uniform or did it get overtightened at one point? Any scoring on the mating surfaces?



Just shotgunning random thoughts here.

I sent mine back to Jegs, it leaked at the back too.

If you noticed the bolts don't go in easily, it's because the
holes in  the combination valley pan/gasket ( I'm assuming that is what you have),
it's one piece, right? do NOT align with the holes in the block.

This causes a slight warpage and leaks...

Yes, it is the combination reusable gasket and windage tray.  The only one where I had a problem was up at the front drivers side corner bolt but I was able to eventually get it.  Ours was also leaking at the back of the pan where it meets the trans.  It seems that the pan is now leaking from the rear sides and not the rear back where it had been where I had put the RTV silicone in.  I have now given up on this gasket and have ordered two of the cork rubber ones from Rock Auto and will use the gasket compound to seal it to the windage tray and pan.

Bakerhillpins,

Yes, I did make sure the bolts were tight and I did double check them before ordering the new gaskets.  They were all still tight so I doubt that was the problem.  The mating surface on the block was in excellent shape and completely cleaned off before installing that reuseable gasket.  The oil pan before I had repainted it I made sure to flatten out the bolt holes as some were concaved.
