Is there any way to fix the haed gasket problem on the 7mge motor so it does not happen again

INSTALL A 1JZ

Sorry, but I have done one on all my 7MGE's and Turbos.
It is that damn # 6 cylinder/water jacket wall being to thin.

Proper prep work done to the head and block, ARP hardware (bolts or studs), a digital torque wrench, and following the tighening sequence that's in the TSRM will keep it from blowing again. I did mine in 5 passes, the TSRM recommends 3.

Agree. The only reason the head gaskgets fail is because the factory had improper torque specs. Do it right ,do it once

I did mine in 5 passes as well.

Kobalt torque wrench. Took them to 85flbs.

Yes you can do the hg thing and do it so it doesn't do it again. I honestly doon't think their is any real gaurantee.

i hear its because of unproper torque from the factory.

i heard somwhere that i was originally made of asbestos then then changed the material and not the torque

Well atleast we are all hearing the same crap.

Shit I forgot to list the most important part, torqueing higher than 58ft/lbs! But thats pretty much a given. I was just listing the things that will improve your chances of not having to do it AGAIN!

I took my ARP bolts to 70ft/lbs. She sees redline everyday, hasn't used a drop of coolant, never overheats, really never gets hotter than 200 degrees even on a 95 degree day while driving it retarded.
