Tomie Head Gasket Installation

[proengines]

As long as the block and head are machined you wont have a problem. If the block is flat and the head machined you shouldn't have a problem either.

Well after reading that i am not sure what to do ?

My head is milled with minimal machine marks but the block is quite visible , surely removing all the coating on a MLS gasket is not necassary when the engine has not even been fired.?

This seems like another waste of money , there must be advantages in using a copper HG as it is more maleable.

So - if my block is assembled and in the bay now - what head gasket should one use? Can i prep the block in there , i don't think so or spray or coat the surfaces for block and not head. I will be running bigish HP - not sure what direction to go in as some other workshops say the MLS will seal when exposed to temp ?

If reusing - tourqing up the studs a few extra puonds should do the trick.- your opinions

I DON'T THINK TORQUING UP THE NUTS A BIT EXTRA IS SUCH A GOOD IDEA , HOW ABOUT USING A COPPER HEAD GASKET SPRAY ON THE TOMEI GASKET , I KNOW YOU HAVEN'T FIRED THE ENGINE YET AS LONG AS YOUR HEAD IS FIXED FROM THE WATER SEEPAGE I DON'T THINK YOU'LL HAVE A PROBLEM

i have a pretty good idea on why mine is weaping oil - the place that decked my head is different to the place that decked my block, and im pretty sure the place that decked the head would not have gone to the "ra" that was required - as they normally do machining for normal motors, not really high performance alloy motors such as the SR20, RB26 etc...

Im going to hit the place where mine is leaking oil with a bit of carby cleaner/degreaser and a air gun and see if i can use some silicon around the place where its weaping and see if that will stop the leak - sure its a bit dodgy and crude, but its on the drain back side of the motor so im not to concerned...

What tha??

I used cardboard from a Weeties packet once for a 138 "Grey" motor thermostat gasket. I guess silicon (sic) is plenty good enough for an RB motor??
