Head bolt torque specs and pattern
 
Hey all. Before anyone flames in case there is a post, I did use the search function albeit with the words that are in my heading and different combinations of them and couldnt find the info I wanted. Im looking for the torque specs for the head bolts and also the tightening pattern as well. Anyone know where I can get that without buying a 150 dollar manual from mitsu? Thank you.

Ok am I dumb or do other people not understand these instructions? When Ive done heads it usually goes one torque spec then another. Ive never had to make marks on the cylinder head before. Thats the only part I don't understand. Where do you make the marks on the cylinder head?

They just want you to put a mark on the top of the bolt and a mark on the cylinder head right where the bolt goes into the hole like an indicator that both marks are lined up. That way you can tell when you've gone the additional 1/4 turn. Not really needed since you can just eyeball the additional 1/4 turn.

Ah ok then. Thank you a ton senate. I just think its strange they don't do exact torque specs. just a 1/4 turn then another. I've never dealt with that putting heads on. They usually just give me an initial torque spec then another final torque spec.
