How tight? Oil pressure sensor
I removed my intake manifold to be ported and found the oil pressure sensor that screws in behind the intake to be loose. How tight should I tighten it up?

That sounds too high... better double check the torque.
I was thinking it was more like 15 ft-lbs since everyone is always talking about being careful not to over tighten it.
Be back if I can find it.

The torque spec for the LS1 oil pressure sensor is 15 lb-ft according to the FSM. I don't have any C6 FSMs so I couldn't look it up. The LS2/3 sensor mounts in the same location, I would think the threads are the same so the torque spec should be the same. I wish I could tell you for sure before you strip some threads, maybe the guy that said 26 lb-ft will come back in and tell where he got that spec from.

Here is the C6 torque specs PDF from the David Farmer website:

As a side note about the torque specs. Cory Harris (ls2 portworks) and my tuner guy both told me not to torque the intake manifold bolts to 89 lb/in as specified in the torque spec from GM. I believe Cory made a post about the brass insert belling at the top and possible cracking the polymer manifold if tightened to spec.
