[duffman1278]

went through the FSM but was still unclear if am shud to put loc tite on the studs that go into the block, that came with my megan exhaust manifold, wen i replace them??? thanks

I don't think it's necessary, just torque em down, unless you're really worried about vibrations

It gets so hot the only loktite that would hold up would be Sleeve Retainer (green) and if you put that on your studs they will never ever come out (this being bad).

I had someone put it on his studs and the studs were too long (and since the only way to remove them would be to break them off, drill them out and retap the hole) he had to spend hours with a file making each one shorter and still keep the threads in good shape. Only use blue or red loktite and NEVER use green (Sleeve Retainer). Purple loktite is for hydraulic systems btw.

so if i put the loctite, stick with the red? being that thats the only loctite i have lol

Dont use loctite. For some reason you break a stud, you're going to need to take the stud out. Some anti-seize, might be a good idea. Or, just hand tighten them and you should be fine.
