Head Gasket

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i heard somwhere that i was originally made of asbestos then then changed the material and not the torque
