View Full Version : Billy Boat "sandwich" gaskets arrived *pics*

Posted for discussion, the long-awaited BB replacement gaskets are here. FedEx priority overnight, 4 in total. They appear to be the normal graphite ones we had issues with, sandwiched with thin copper with a rolled edge on one side...also pic comparing heavymetal's solid copper units.
Click the thumbnails to enlarge, then click that pic for full size :)

I have 6 gaskets now, lol, wondering which ones to use where.

Heavy, what do you think? Why did Billy sandwich them? Save money? or do you think the graphite inside would help give a little to help seal? or would your solid copper ones do the same?

thats a hard question i think... I think they might do the job... heavy's seems to be built to last since they are solid, the others could be just to make sure they do make a good seal...

How thick is the copper on billy's?

later blitzer

A sandwich style gasket is fine for matching uneven surfaces, but because of vibration, will tend to collapse as it is "rocked" by the joint. Check and retighten often (a good idea anyway).

Depending on the wall thickness of the "fold over" the blowout potential is probably good.

Leaks are another issue.

Someone said they used copper RTV on both sides of the solid copper ones.
I didn't hear of any complaints, but then I haven't heard that it sealed either.

I can tell you that the copper reducer rings I have on my BB header to CORSA exhaust setup don't leak.
