Thanks for following up Mr. Orph. Another 1 for me please. If not possible, then i can take one to "Industrial Gaskets" in Melrose Park, Adelaide, for replication. I phoned to ask what they do yesterday.

ANY gasket for ANYTHING if you have a template or S/h in reasonable condition, and will do one off's. Haven't asked for pricing yet, but can't be too bad with latest technology to make them.
Back to the original thread, I got a second opinion about the loud tappetting noise from none other than proffessor OZ yesterday. Just that we believe, and not a manifold leak

. Thanks OZ for spending the time and almost an hour went by talking Belletts and stuff out the front yard

shame i had to push on, mate.
So it's time for some gap adjustments instead. All other vital signs as should be and runs like a wild dog

Cheers, B.
