The gasket on my oil dipstick has deteriorated. Can it be replaced with a plain rubber gasket or is it a specialized item? The remnant has a groove that it fit on the cap with but that may just be there from use. Purchased RV8, not a builder. Thanks.

Have been using a sikicone gasket for several years. Works great

Okay. So while reading your opening post I was thinking you are asking about the actual dipstick gasket, the O-ring under the dipstick cap. But now folks are directing you towards an oil filler tube gasket thread.

Now I have to re-assess. Are you asking about he dipstick cap O-ring or the oil filler tube the dipstick screws down upon?

If it's the dipstick cap gasket it is an O-ring is Lycoming part number 74068. The REAL gasket company makes a red silicon type which seems to last longer. And there isn't anything too special about the O-ring as long as it's petroleum resistant like the MS25913 series O-rings.

If you were in fact asking about the oil filler tube gasket then see the link in the second post in this thread.

Yes, the dipstick cap gasket. I'll take a look at the suggested parts, thanks!
