new oil pan gasket?

[iselltonsofthings]

Ever since I started powdercoating, I've planned on doing my SHO engine from top to bottom to sho people what can be done.

One of the questions is that I have a brand new yamaha 3.0 crate engine. It has been properly stored away for the past 13 years. It is in mint condition stored in a heated garage.

The question is: I'm going to be powdercoating the oil pan along with just about every other external metalic part. Should I replace the seals, ie. the oil pan seal with a brand new one?

Remember, this engine has been sitting for the past 13 years but it is truly in 100% flawless condition because it was stored under a cloth blanket in a heated garage. It is truly mint and all caped off from the factory. It is the original motorcraft filter and oil from 1990.

Do you think that I actually need to get all new rubber seals or can I reuse the oil pan, valve cover seals, etc.. ?

Let me know. Thanks much!! Scott

the oil pan seal is actually 2 rubber end seals and RTV Black Silicone along the sides. i dont know why youd choose to powdercoat an item that wont ever be seen, unless you plan on having it set on ramps or jackstands for extended periods of time for maintainance. "hey, the SHO is broke again, but hey, lookie at that powdered oil pan !"

it has been discussed before about seals sitting for a while and not being used. its all personal preference. but in my opinion, which wont really matter to you, is they could lose their natural oil, dry out, and fail. so you replace one gasket, then another will fail on you. itll be neverending.

I agree that I can't see why you would powdercoat the oil pan, plus powdercoat holds in a bit of heat which is not needed in the oil anyway.

I would spend the $17 for a new Felpro oil pan gasket set, though. The old ones have still been compressed, and the RTV will need to be redone anyway. I wuld reuse the valve cover gaskets, as they should be fine.

Thanks for the replies. The reason that I was going to powdercoat the oil pan was for a real life example of how nice everything will look after it is all powdered. But after thinking about the heat retention, I think that I'll opt. not to powder coat the oil pan. There is heat fins for a reason and to insulate it would not be beneficial. Thanks guys for giving me a heads up. Much appreciated!! Sincerely, Scott
