Sounds like a 3/32" O-ring would be very bad, esp

with a bit of crud

build-up in the groove, or even sealant.  Using

sealant sounds like a

bad idea in that this fills the expansion volume and

will either force

the sealant out when heated or break something.  Non-

curing sealants

probably extrude when heated the first time.

SEALANT??????!!!!!! ........ There shouldn't be no
stinking NOTHING in that groove but the APPROPRIATE
seal, PERIOD!!
