HI,

I'm in the process of putting new cylinders and heads on my engine.
I've read the articles NOT to put the paper gasket from cylinder to
block - so I won't.
I've read to use a sealent, choices varied, Jan mentioned a thin gasket
sealant ( not sure what) as there were thoughts a "thick" sealant ie.,
permatex will change the compression ratio.

So do I have to ...in using a permatex - which is available here;
put thin layer on block and cylinder seat -

-push cylinder to block, put heads on; torque head nuts to proper
specs, take head off, this will "seat" the cylinder true to block, THEN
measure distance from piston top to cylinder top??

This seems like some extra work that I've not herard being done.

Otherwise if there is concern that a layer of sealant will change the
CR, why is this not suggested to be done? ie, the initial bolting of
head to compress the sealant for final CR measurement?

Maybe I'm misunderstanding what was written before - is Jan's opinion
not correct?

Thanks for clarifying!

I thought this would be less complicated, but I'm learning...

.......Just note that removing the paper
gasket will raise the compression ratio ever so slightly. And using
"RTV
Silicone sealant" will result in lower CR than using the (in my
opinion) proper, thin sealant. Conclusion? Use the rtv silly-cone
sealant if you
found a paper gasket and decided to leave it out.

End result is close to being same CR. (The difference in CR is marginal
this way anyhow, I'm
just saying it to reveal some of the "finer details" I talked about
yesterday )
