So I am a long time reader but brand new member of Supra forums. So Hello all!

I am a first time supra owner, and of course it blew the headgasket last fall. Its been in surgery every since. I have rebuilt SEVERAL chevy engines and 1 22RE toyota engine. but never a 7M.

My prob is this, the machine shop had to mill 7 thousandths off the block deck. didnt seem like much to worry about until i put the cometic MLS head gasket on and realized that there was a slight ridge from the block to the timing cover. I asked my machine shop what to do, they said just loosen the bolts on the timing cover and bolt the head down, (it will force it flush) and use a small dab of silicone on the joint. I did so, but now i am wondering about the seals on the crank (front main) and the countershaft seal. Wont this distort the seal with all that pressure pushing down on them? and cause a leak?

Has anyone had any problems with this? if so did you have to mill the timing cover? if so please help!

Thanks again!
