1. head retorquing question (score: 1): Author: "DON SCOTT" <rowdon@sonoma-county.org>; Date: Tue, 02 Sep 2003 10:45:20 -0700; Can anyone offer some tips on this? When retorquing a head, is the proper procedure to back off each nut/bolt then retighten, doing them all in recommended sequence? And when backing off, how much?

Backing it off a bit the crud on the threads so you get an accurate reading. Just back it off a small amount. You do know to do this one at a time; /html/mgs/2003-09/msg00023.html (8,630 bytes)

Do this from the middle of the head crosswise. Cheers, Hans not head iron by /// or try http://www.team.net/cgi-bin/majorcool /// Archive; /html/mgs/2003-09/msg00024.html (8,890 bytes)

He would unbolt the head bolts one at a time in order, then re-torque the bolt. He never had any more than on bolt loose at a time.; /html/mgs/2003-09/msg00027.html (9,927 bytes)

Whenever there was a tune-up and valve adjustment, the general consensus was to always have the heads re-torqued. Some people; /html/mgs/2003-09/msg00031.html (9,105 bytes)

Static friction represents the force needed to get a stationary object moving. Sliding friction is the force necessary to maintain that movement.; /html/mgs/2003-09/msg00032.html (9,143 bytes)

Re: head retorquing question (score: 1): Author: WSpohn4@aol.com; Date: Fri, 5 Sep 2003 11:45:38 EDT; No, you just back them off enough to break any corrosion bonding and to ensure that the 'pull up' to the proper clamping torque is a 'sliding' reading. Probably a quarter trun is enough to do this. O; /html/mgs/2003-09/msg00060.html (8,802 bytes)

Re: head retorquing question (score: 1): Author: "Bob D." <bobmgtd@insightbb.com>; Date: Fri, 5 Sep 2003 13:05:04 -0000; One could make the argument that the bolts that "need" to be retorqued have already broken loose. Anyway, I was once told that retightening the head necessitated a readjustment of valve lash. Is this; /html/mgs/2003-09/msg00062.html (10,042 bytes)

Re: head retorquing question (score: 1): Author: wcam46@netzero.net; Date: Sat, 6 Sep 2003 13:55:17 GMT; I just re-torque to a higher level - do it at 45 or 50 first time, then 50 or 55 when retorquing - they will move, and there's no need to loosen.

In theory any change to the head bolts will change the valve clearances, but unless the head was actually loose I doubt retorquing by a few; /html/mgs/2003-09/msg00082.html (8,517 bytes)
