Hey all,
Well I just replaced the two expansion plugs on the intake/exhaust side of the block with new brass ones and they both leaked on me. I put them in dry and seated them about a sixteenth into the casting.
I pulled them out today and am going to try it again. This time i'm going to really clean the machined surface well with emery (probably 600 grit) and but some sealant on them.
I'm thinking of using Permatex Aviation Sealant but am open to a different type that others on the board have used with success.
If you go the sealant route, is there a prefered type for this application?
I really don't want to do this again!
