P053 is the code and


What are the torque specs for the intake plenum to manifold screws?

 

hmm...I dont see that code on this list

I searched some other forums, and that code never came up

 

I don't know what the spec is right off hand but I can't imagine it being more than 20 ft-lbs, if that. I broke the OEM bolts loose with a 5/16" socket on a 1/4" drive ratchet easily. Remember, you're dealing with a cast metal with somewhat weak looking ears for the bolts and going into a plastic threaded hole. There's no real load on those bolts, they just have to be snug enough to tighten up on the gasket and form a seal.

 

0053 or 1053??
