1G Good material for replacing lower timing gasket?

[Barra]

The lower plastic timing belt cover has a rubber gasket that gets hard and brittle over time. Mine is missing random chunks. Has anyone found a decent replacement for this? I could go the route of just buying an whole new OEM cover but for now on this motor I'm hoping to just get a decent rubber seal in there as the actual plastic cover is fine. I though of using the rubber strip used to hold window screen mesh in the frame but it is somewhat square in cross section and the original gasket has a more rectangular cross section.

Try looking on Mcmaster-carr. Between rectangular o-ring and rubber sheet material, you can likely find the right stuff.

Have you verified that Mitsubishi doesn't sell just the gasket? if they dont then I would just fill it about half way up with Permatex ultra grey and let it cure for several days, that should do the trick and then just bolt it up after its dry, that is after removing all of the stock hardened rubber thats in there, if its hard its not doing anything anyway.

MD188834 is the 2g timing cover rubber gasket that goes all around. I bought one for my 99. It may fit your 1g assuming the groove is the same. Only $3.80 at https://www.mitsubishiparts.com/oem-parts/mitsubishi-front-cover-gasket-md188834.

I don't believe it, they still have the 90-92 gaskets in stock as well. Never would have expected that. I just ordered, we'll see if they actually arrive.

*EDIT* Nevermind, just got an email stating it is discontinued and order is being refunded. I'll have to look and see if the 2G gasket is still available and if I can make it work.
