Head bolts and locktite

[MarkB]

Hi,

I'm ready to install my head, and was wondering if you use locktite on the head bolts. I'm thinking not since you re-tourque after the first start-up, and that would break the locktite.

Also on the re-torque after start-up, I know there's some torque angle specified in the BMW manual. Do folks just re-torque to the last torque setting?

Thanks!

no loctite, just lightly oiled, and only angle torque if specified, I thought m10 was still ft/lb torqued

DEAR GOD, NOOOOOO!!!!!!!!!!!!!!!!!!!

(Well, actually, the loctite probably wouldn't set till you were done.

But the next person to pull it would be confused...)

And yeah, the latest version (even from BMW now) has

a preliminary torque, then a couple of degree measures.

It works better.

Thanks, no locktite.

how do you perform a degree torque if you have a clicker torque wrench...imagine a circle?

[AsbestosIcan]

The use of a torque angle protractor that snaps on the wrench . It looks like a dial that measures degrees in a circle. you had the right idea picturing acicle

[TobyB]

...and those of us who are too cheap to buy the right thing

use something made of a degree wheel and a

breaker bar. If you're a bit creative and careful,

it works pretty well...

Autozone sells a degree wheel for torque wrenches for about 15 bucks. used it on mine, 15k miles later still running fine

How many degrees after initial torque?

last time I did it, the specs were on a sheet of paper that came with the gasket set.
