I Have a 2003 Blazer L/S 4.3 liter any one out there help me with the torque spec,s on the upper intake manifold bolts and the valve cover bolts.

 

rThe values you are requesting have been requested and provided in past threads. A quick search for either "intake+manifold+torque" or "valve+cover+toque" (without the quotes) will turn up the relevant threads/information.

 

Tried that. Getting nowhere....

 

See this thread, post 14.

Lower intake gasket replacement - Blazer Forum - Chevy Blazer Forums,

Install the manifold and bolts and tighten the bolts in this sequence:



Tighten the bolts in sequence to 26 inch pounds (some versions of the factory manuals say 27 inch pounds, but I doubt 1 inch pound difference matters).
Then tighten the bolts in sequence to 106 inch pounds.
Then tighten the bolts in sequence to 132 inch pounds (11 foot pounds).

This is a job for the 1/4 drive "inch pound" torque wrench.

 

Thanks for all that information but the search for torquing the intake manifold was just an example in the previous post. I was looking for u-joint and pinion nut specs. I posted here because I did a fair amount of searching in the forums with various keywords and just couldn't come up with anything. I got some specs from the net and wound up snapping a u-joint bolt so had to remove the pinion flange to remove it. Now I need to torque that back on...
