Check the torque on those VLOM bolts.

What is the inch pounds torque?

On the manifold bolts the instructions I’m following show torque all to 44 in lb then to 89 in lb

Same as the NBS V8 spec.

If you trust the accuracy of the foot pound you have, go 4 ft lbs and then 8 ft lbs and will be good. I know when you use the click type torque wrenches and you hear the first click, everyone always clicks it again 2-3 times and that small movement is actually torquing more than what was asked for.

Lol I don’t. I got a new torque wrench needed one anyway. Got everything put back together, codes gone, oil pressure sensor working properly again. Got a little bit of smoke on startup but II‘m guessing that was due to the spilled fuel. Outside of breaking the pcv hose to the intake and having to replace that ($15 from the dealer) it was a pretty easy job. Thanks everyone for the advice. I swear this is the most useful automotive forum out there.
