RTV gasket for D264 front covers etc.

Dalrymple · Apr 27, 2013

First, I'm a very firm believer in modern RTV silicone sealers in place of gaskets in most places. I buy a gasket or make one only when there's a compelling reason not to use RTV, such as when a critical clearance is maintained by the gasket thickness, etc.

That being said, is there any reason not to use RTV for the front crankcase plate, injection pump mounting and pump gear cover? The Super MD has a slight oil leak that I believe is the pump gasket, but may be the front crankcase plate. I'm just wondering if I should buy gaskets before I tear into it.

I used Permatex Red RTV on the front plate and timing gear cover on my gas Super M (C264 engine). It's been together for 10+ years - it has never leaked a drop. I would not hesitate to use it again.

Tip: Immediately after the parts are assembled wipe off the excess RTV that works out between the parts. Otherwise the stuff is a bugger to remove once it's cured(!)

Both my mds leaked at the front cover there at the
pump...used the rtv sealant and it seems to be holding up
good so far. Jim.

it ll work, personally I would use a shellac
compound on a new gasket. permatex indian head brand
is my choice. maybe I m fussy, just sayin .
