Hi all,

I searched on 'gasket glue' but did not find a reference other than intake and exhaust hence the post.

I am about to put my cylinder back on the block and was wondering if I should use gasket glue on it?

The old one is hard to get off but I don't know if it is has glue on it or not??

Many thanks in advance.

try searching for "permatex" or "sealer"....you'll get buried, lol

anyway, it's an easy answer...

when it's time to replace the cylinder gasket, i clean it and apply a coat of high-temp rtv to the bottom of the jug. nothing else. if you have decent gasket material handy, use it along with the sealer. warning: if you don't replace the gasket, give it a dry roll to make sure the piston doesn't slap.

just askin', but you're aware of the procedure for removing and replacing the cylinder without hurting anything?

So you don't put any sealer on the block side at all??

I recently viewed the ring installation post thank you and was aware their was a pin from working on my dirtbikes but was not aware that the ring ends no the happy times where beveled so will keep an eye on that. The rings in the dirt bikes use a stepped ring end.

some rings are stepped, some are beveled, the depth of the pin differs from version to version too, and mix-n-match can be fatal...another fine example of fragmentation at china's end.

putting a good layer of sealer on the bottom of jug seems to be the cleanest way to get the job done, you'll be using your hands to get the piston-pin and keepers in place, if there's permatex on the block, it will soon be on your hands instead.

UPDATE: lately, i've had 2 different cylinder-jobs where the piston lightly hit the bottom of the head if i left the gasket out, so i now have to advocate replacing the gasket...2 layers of cereal box all gooped with blue rtv is working fine for me.

How does that cereal box hold up compared to the gasket material you can get at the auto parts store?
(I like berry krispies cereal right now-:LOL:)

And what do you use for the top gasket material or do you buy one for that?
(I'm assuming the top gasket is the standard aluminum type)

rtv copper is the stuff i use and it says something like do not use for headgaskets cause i had the same idea

the firm cardboard holds up very well for the base gasket...i personally use no sealant on the headgasket ever, and have never had the need to replace one, they hold up real well. if you've damaged yours and cant get a replacement, i guess you could try a heavier piece of aluminum. i hope i don't ever have to make a head gasket.

Yeah the head gasket has to be a soft metal to take the abuse and still seal but I think I could cut one out if I really had to.
It would only have to cut the five holes but what exact material would it be, oh well I'll worry about that when it comes up.

did you put gasket sealer on both side of the gasket? I am preping my engine now and wasnt sure, same question for the head gasket.
Thanks
