Elan M100 Scratch Rebuild

Ok, howdy heavenly beings,

Running out of places to look for an answer...

Is there such thing as an m100 oil pump gasket or do I have to make my own?

On the (rear) face of the oil pump (to 75% of the block) are the 2 oil pickup/distribution feeds. Bottom one sucks, top one blows. On the pump side, there is what appears to be a gasket seat (pics) but nowhere can I find mention of any kind of gasket.

On disassembly, mine were filled with a black silicone type gasketesque material which was an absolute B*$*4rd to remove. This stuff extended completely around the mating faces of block and pump.

Thanks for the info guys! I always make sure mating surfaces are free of old bits of gasket, paint etc after a fascinating issue with a plastic thermostat housing and a ford ka...hehe!

Take great care that you don't spill too much liquid gasket on the inside, or you'll be scraping it out the oil pickup filter later.... if you're lucky :burnout:
