Oil Pan ????'s

[MarPar]

A MoPar buddy of mine told me that years ago, there were these "tabs/plates" that one could put in-between two bolt holes of an oil pan (one for each set of 2; all the way around) that would create even pressure and help stop the pan from leaking. anybody every heard of this??

my g****mn oil pan (440cid) keeps leaking and this will be the fourth time i will be changing the oil pan and windage gaskets. and im getting pretty damn tired of doing it. the last time i did it, i took my time and did everything i could to not have it leak; i smoothed all the dimples out of the bolt holes and made them nice and flush (the pan rail on the block is nice and smooth and not messed up at all) cleaned ALL the gasket material, then carefully put the gaskets and some ultra black on it, waited two full days to let it cure, and it lasted all of last season, but now it's leaking again!!!! :angryfire:

not sure if it has anything to do with it, but i have a stock 187 (c-body) pan on it now--as far as i can tell from decoding the block it's a b-body block--should i change it to a 402 pan?? will that make the difference??

i know i could get a milodon pan, but i want to keep her as stock-looking as possible.

i can get pics when i get home if y'all would like....

comments and suggestions from the guru's are very much appreciated---your humble black sheep, Mar :grin:

Hello. I have a 402 on mine and dont have any leaks. I am using a felpro gasket. Do not know if that makes a difference. Good luck.

Thanks Dave! i bought steel gaskets wrapped in silicone (? cant remember exactly) or rubber. i hope it helps some...

I saw a show where they used 3m weather strip adhesive to seal the pan and windage tray, looked like it worked good have never tried it yet but was considering it.

Have you taken the pan and knocked the bolt holes back flat with a hammer? That's usually what makes um leak is when you forget to do that. There IS a torque spec and people usually overtighten the bolts to the point that it bends the pan around the holes and it will no longer seal.

Yup....just like the notorious tranny pan on 727/904. 80-100 in/lbs is all you need.
