Im replacing a buddies manifold on his 98 tacoma w 2.7L. What are the Torque #'s for the bolts? Ive searched and i cant find it. Thx.

 

did a simpl search such as FSM or service manual,
torque specs

 

I think its 36...its either 26 or 36.

 

I think it was 38 when I put my LCE on... might have been 36 though like said above.

 

yeah i'm not sure...its some where right in there...check a haynes manual

 

I put TSM - toyota serv. manual - oops. Thx.

 

uh, well i did it at 45 lbs - seemd good, not over tight -not under. I'm always worried about stripping the head out after a jeep i did years ago. thx for your help.

 

dont worry about the head, worry about the body itself. reusing old bolts and overtightening them will strain the bolts so much that it will, eventually, break.

 

I would be far more worried about ripping a god damn hole in my head and having to drill and tap, if not buy a new head, than breaking a bolt. I actually did reuse my old bolts, the ones my LCE came with would NOT thread in right, after crossthreading every time for an hour and not wanting to damage my head, I just used the old ones. Worked fine for the 20k more I had the truck.

Remember to give 'em another tightening after 100 or so miles too

 

i resuse all my bolts, even head bolts.

what i am saying is that not to overtighten them, go w/ the specs. at a certain increase of stress you put on, the strain(lengthen) will increase and the deformation will stay permanent due to heat. the stretch will lower the tensile strength, and could result a failure of the bolt.

not to mention, a lot of bolts get seized over a long period of time, so you want to retain a highest tensile strength when poppin it out w/ a cheater bar or impact.

thats the idea about reusing bolts when overtightening them.
