gasket sealer woes..

[Glen]

Heres a question.

im trying to find a decent gasket sealer and all the ones ive tried so far have failed pretty epic.

ive only used the blue hylomar, some semtex aviation gasket sealer and RTV silicone.

the RTV isnt useful anywhere in the engine because it just flaked off on contact with petrol pretty well instantly and broke off in big chunks, so i was a little worried about it chewing the engine bearings.

the Hylomar and semtex are excellent for the inlets ive found and on the crankcase halves, they sstay in tact and all.

BUT the problem im having is on the base gaskets. im using a special polini cylinder with the water journals all the way through the cylinder like a blata that i cant plug up and the water / petrol together is just dissolving everything i put on there. the hylomar and semtex just peels off like it wasnt even there to begin with.. and after about a week i can see a teeny bit of atomized fuel/water ooze out the base around the water journal.

any recommendations for a water and petrol safe sealant?

i fond the dark brown non hardening aviation gasket the best

you can buy a copper based gasket sealer in a spray can its specially for head gaskets & exhaust manifolds etc etc

this gear is the go for everything as you can spray a coat over the case deck & the bottom of the cylinder & let it dry overnight then b4 assembly spray both sides of the gasket let it touch dry & it will stick like poo to a blanket ill see if i still have the can & get the name of it for ya

last option is to cut your own base gaskets from thin rubberized cork used for carb gaskets on older cars

cool if you can find the name thatll be tops. the non hardening stuff is the semtex im using. i like that as well. just doesnt want to handle the water too well

ahhh that's where my can went

that's the stuff glen good gear M8

it will fill in any lows or Pitts, you can also build it up in a couple of layers & let it dry just clean the surface with thinners or prepsol to remove any oil

or use it as a glue/ form a gasket by spraying on let it almost touch dry then sandwich the gasket between the stuff
