Old Race 340 Teardown

He's gotta have "something" to seal the distributor. He said the distributor does not have a machined slot for the O-ring seal.

To the OP, here's what "I" would do. Spray both sides of that existing seal with a good coat of Copper Coat spray and let it tack up. It never dries completely, so it will stand the distributor being turned to adjust timing and still seal fine.


Right, I knew that. That’s why I said not to stack them.
