I need sealant for the two halfs of a crank case. I've got some 'instant gasket' cr@p from halfords that i've used on a sumps before an other low pressure/temperature areas don't wanna use that. I've read a bit about 'yamabond #4' and silicon type RTV sealant?, need something that will hold good pressure and won't leave me with oil p!ssing out everywhere and a 2 stroke that wont run properly! What are people's sudggestions and what have people used before? Ideally I need to pick some up at the weekend dont wanna be waiting weeks for some to turn up through ebay or whatever

cheers, tom.

This is the one I use - Blue Hylomar applied to both sides of gasket.

awesome thanks bud i'll have a look, althought the engine doesn't have a gasket for the two halves.. this stuff is the gasket Which is why i'm gonna do it with the proper stuff!

wurth silicon rtv is the stuff you want. different types available to suit all needs

As stated in my pm, use either Wellseal or Threebond from Yamaha, both are designed exclusively for sealing flanges where there are no gaskets used, I use them to seal crankcase halves, the Wellseal seems to be better but Threebond may be easier to get hold of.
