Realistically, loading a cylinder sleeve at 105 ft lbs of axial clamping load
onto a copper figure of eight ring at the bottom is likely adequate for
sealing. The coolant pressure inside the block is perhaps 12-22psi. I
currently do however put a dressing under the sleeve. Hylomar M is what I use
as it is very thin once applied. Gasket shellac is arguably just as good. The
key is a thin coat. Most all sealants get pressed out of the pocket anyways. I
was thinking that a future iteration of a cylinder sleeve I would experiment
with a silicon or viton oring placed at the bottom of the cylinder sleeve which
has an imbedded groove. This however is more of a thought experiment and is
more than is really needed. Alternatively, I was also thinking of cutting some
rings made from thin teflon sheet and place it on the underside of the sleeves
with the figure of eight gaskets.
