Oil Return Pipe Gaskets

[Dick Deegan]

I am currently doing some work on my engine - changing head gasket, resurfacing the head to ensure flatness, valve work etc. I always install new gaskets when I remove and re install the oil return pipe.

Much to my surprise, when I received my order today my supplier had sent O rings instead of the traditional flat cork gaskets.

Any one ever use O rings in this application? O rings normally need to be secured in a grove etc in order to not move around and maintain stability. I am afraid that the O rings will migrate into the open part of the pipe and lead to a large oil leak.

What do you think?
