Pick up a OPSU socket (10 bucks) from a parts store, I put it over my sensor to give it extra protection while I took intake off and put it back on. I left it over the sensor until I was completely done, then took it off and plugged in the clip. It saved me from breaking it after I just replaced it.

Il definitely try the opsu socket to cover it till its all put back together ive read they are easy to break. I will probably just order the pcv valve and hose and look into the knock sensor manifold gaskets are in the mail.

Inspect your knock sensors for rust and the harness wiring for issues. Replace the knock sensor harness and harness if necessary, then rtv the caps for the knock sensors to avoid rust in the future.
well, looks like someone already mentioned it and you have a harness coming. Rtv upon install.

Rubber bands will work too ....2 rubber bands will take care of the 4 rear intake bolts. Lift the bolts up and then hook the rubber bands around them. Then you can lift the intake up and move it forward. When you remove the intake manifold lift it STRAIGHT UP BEFORE you move it forward. If you tilt the front of the intake up the rear of the intake will break off your oil pressure sending unit at the base. It is a plastic POS and very EZ to break.

Why would you pull ihe intake to change OPSU ( oil pressure sending unit )?
if that is the only reason just buy a special socket ( 15-18.00) designed to remove and install opsu, and be finished before you even get out the tool to remove the intake.
just my .02'

I'll also agree with everyone mentioning replacing the intake manifold gaskets and giving it (and the heads) a nice, deep clean.
I'd also skip "fixing" anything with the stock PCV system and just do the '04 LS6 PCV conversion. For less than $100, you'll clean up the engine bay and have less oil consumption.

The best way ive gone about making sure not to break the opsu is to pull that vacuum hose around the back to the pass. side of the engine bay. I use clothes pins to hold the back bolts up and it works for me. If the knock sensors and harness are good, Id put rvt around them to seal them good.

This is before the LS6 PCV, notice the thick line running down the passenger side head?
This is after, no clutter and more efficient!

Just did the LS6 Pcv swap this afternoon. Was time consuming but it was well worth it. The old Pcv hoses were all clogged up and gross.
Word to the wise. Take off those stupid brackets on the drivers side fuel rail and the bracket on the back of the drivers valve cover and toss them in a drawer. Makes getting to the manifold bolts much easier
