3. I agree on a point about the correct setting procedure for a gasket maker,did OP do it right?What I think...this isn't a vintage car part that is really difficult to get,WHY don't you get a $90 piece and do it the right way?Wrong place to make economy.Am I wrong?

All good advises, been there done it on item 1. This is o-ring on the twin pipes on the WP sides on the M64 V8. Then I mis dianosed it, replaced VP gasket instead which was good

and still leaked until I did pressure test. All good for now (knock2 on wood) as far as cooling.
