Gaskets on Sump Plate

[redcar]

I checked "search" but did not find an answer to these questions: 1) when replacing the sump plate and sump screen -- should there be a single gasket between the plate and screen -- or should there be two gaskets -- "sandwiching" the plate with a gasket between the plate and screen, and then a second gasket between the screen and the sump casting?; and 2) should you coat the gasket(s) with anything? - engine oil, gasket sealer?

Thanks,

Bob

I tried the "no sealer" approach and was unable to get the oil sump plate to seal properly. Thinking my plate was no longer flat I replaced with a URO Parts replacement and still had no luck making sure I've got new washers/nuts/gaskets each time.

I finally gave in and used Loctite 574 flange sealant as per the Sump Plate installation on your Porsche Air-Cooled Engine video from Klassik Automotive Training School's YouTube channel. I should have known I wasn't going to be able to seal with paper gaskets alone. Gasket sealant was used previously.

Often the leaks are due to slight edge where the case mating surfaces come together. Run your fingernail across the case parting line, if you can feel an edge it is a potential leak, doesn't take much. Once sanded flat it has cured many leaks. The last place I want sealant is at the pump inlet area. The gasket surface on that strainer plate doesn't look too good either.

I agree that the strainer plate surface isn't good. Are there replacements available? I'll have to do the fingernail test at the next oil change.

Silicone seals are really good for the sump and valve covers. Easy to use, reusable, and they don't leak.

I don't see the sump seals on Bob's site, but I am sure they have them available.

Happy New Year,

Are there replacements available?

Is eBay the only source?
