i did a coolant flush this weekend and went with the 180 t stat and it made a pretty good difference. i love these cheap mods. but anyway i noticed my exhaust manifolds keep loosening up. ive used loctite before and it didnt hold any ideas

 

Stock or modified? How did you use the loctite?

 

there is a locking nut or bolt setup out there but I've never used it. check with Summitracing.com and see what they have.

 

yeah summit has locking header bolts the set is like 46 bucks though. I think I'm just gonna use some lock washers

 

are these the studs coming out of the heads or the bolts?

 

there bolts. the heads were replaced by the dealer when i bought it so im sure thats why this all started. as far as the loctite ive done it twice but i make sure the motor is completely cool then i take one out at a time apply it to the threads and then reinstall. i dont use the truck for roughly 12 hrs after just to make sure it cures. but i also dont want it to seize in there. i considered the locking washer idea. and $50 is expensive for bolts granted i may not have much of a choice. oh and the truck is stock other than the tps mod and a 180 t stat but thats really arent what your talking about as far as modified im sure.i plan on going with headers when i have to do my exhaust but until my exhaust goes it will stay as is.

 

Had this same problem with mine after I replaced my cyl heads. Well, actually only on one head but anyway : what I did was get all brand new bolts and studs and nuts and washers from the dealer and new Fel-Pro gaskets from NAPA and put it together with loc-tite and haven't had any further problem.
