Oil Pan Gasket

[Deamaker 5]

So I will toss this out there to the community to see what people have had success with when it comes to replacing the oil pan gasket.

Do you prefer the old cork gasket with maybe a small film of silicone, or the newer nitrile rubber gasket?

Please let me know your thoughts as to the best way as to reduce as much leakage as possible because we all know they leak; I just want to minimize my leakage!

Thanks.

cork gasket Blue Hylomar , no leaks .

...times two.

Oil pans and valve covers should not leak if gaskets are properly installed. You might want to place yours on a flat surface such as a glass table or table saw and use a feeler gauge to check for gaps.

Yes, both Healey Nut and Michael are spot on. Maintaining a big Healey 6-cylinder racer, my oil pan often has to be R & R'd multiple times throughout the race season and the system described always provides the perfect seal.

Thank you for that info

Ok thanks

Do u reccomend to apply seal to one side of the gasket first to the pan and let dry then apply seal to other side before mating ? Or does it matter - should clamps be involved to apply gasket to pan first ? Thanks just want to do this the right way because nobody I am sure wants to do it twice - thanks

Apply Hylomar to mating surfaces and assemble everything . Don’t overtighten it or it will leak because you deform the pan edges . Make sure the bolts have those fancy oval washers on them .

So I am working on an aluminum heavy duty oil pan not the original steel one

Deamaker--

Nothing changes--just make sure the pan is flat before you start.

I find it easiest to first coat both sides of the gasket, carefully line it up and put it onto the flange of the pan, perhaps giving it a few minutes to tack off. Then, while holding the pan in place with one hand, with the other hand--or a helper--start (not finish) one screw in the middle of each long side, then do the rest of the screws, tightening them gradually so as not to distort anything.

If you are working from underneath the car, that aluminum oil sump can be a little heavy making it difficult to line things up without disturbing your gasket or sealant. I made a few alignment studs that made the job quite a bit easier. Very simple to do.

I appreciate that as I have the locator pins in hand and just waiting for my gasket to arrive - thanks you look like u got a nice Jules frame there -

 

[Lin]

Yes, I do. RIP Marty.

I always learn something from Lin.

so while I have you guys on the line here , do u think I can take this brake line off to get the forgotten bolt in and not lose too much brake fluid ? Or just bleed the whole system again
