BigKev's explanation in post #13 above is the way i always did it and i think the manual explains it that way too.

Also look for the ridge or recess in the bore of the block as he indicates. IIRC there is a ridge but i'll have to go look again at my spare block.

For a sealer i use a little bruch on permatex just for safety but it's probabaly not necessary.

Welch plug is what i always heard among the manufatureing crowd but the term rarely used in field service.

Thanks Jack for the tip on the plug diameter. I was not aware of that. Haven't had to replace one in a Packard yet.
