Very nice work.

Did anyone check to see how close to hydrauliced the "O" rings are in the groove?

Are they stiff enough to require any additional torque on the case bolts?

Lynn,

That was one of the reasons I sent a hsg to Creavey Seal.........There was concern

that the early callout for the inner coolent seal with a .098 cross section could cause a

hydraulic rupture of the narrow seal groove into the coolent area........As to requiring

additional case bolt torque I will take an uneducated guess of no.........Even though

the TES seal are stiffer (the Teflon outer cover) the Silicone center core is very

compressable.......The question of a hydraulic problem was one of my main concerns

and Creavey sized the cross section to meet these requirements..........Subsequently

the inner coolent seal cross section was reduced to .093.........
