head keeps coming loose
- Thread starter roadkill
- Start date
i have a cometic EST head gasket on mine and i torqued it one time when it was installed in april and never again (wich is what cometic claims they do). to this day there is not a single drop of spooge leaking out so mabey give one of those a try next time???
yea are you using washers under the nuts all the same thickness, and put a little oil on the tread to torq it correct, must be able to finger tighten them all the way before torqing. re torq after approx 1- 11/2 hrs run time if needed. Washers keep it from reaching the end of the threads on each head bolt for a consistant torq.
Do a couple of heat cycles then retorque. Warm it up completly ,let cool down comepletely (couple hours), repeat process .
thats what i keep doing, ive done that so many times and it wont work, would putting locknuts on help?
Guess at this point it won't hurt. I think it would take more than 200*+ that a head runs to melt loctite.
I would use lock washers , tighten , heat cycle , retorque and that should do it . You might have stretched headbolts you might wanna get a new set the next time you do a top end
i would by some new studs and nuts, threads are prolly just stretched too far, i would do it now before the threads are screwed
