OK, Bought a 07 with a couple problems today.

So once apart, I'm starting to think maybe his story was not entirely BS but no way to know for sure.
The cam sensor looked newish, The VVT Magnet is the new style and it also had a new VVT solenoid but why not change the oil pump and o ring. Seems like a no brainer to me.
After installing a new milling 365HV pump and swapping it to the green relief spring.
Im happy to say i have 60PSI cold oil pressure. Hot oil pressure seems to be 35ish PSI.View attachment 442205View attachment 442206

I'm running the same oil pump in my 2012 XL Denali and I see the same oil pressures. Good!

On the motor mount, you're going to want some kind of heat shield in there or that rubber fluid balloon in the new mount will dry out and crack faster. I was able to get a new one in with the heat shields when doing it from the side through the wheel well. Too late now I suppose, but rigging up some sheet metal in there would seem a wise investment of time.]

On the diff mounts, they can be replaced with the diff still in place. Takes a little finagling but I was able to do it on my '07. If you decide to pull it out, it might be worth just resealing yours. It's not a terrible job on the bench.

Time will tell if putting a new pump in cured it or just prolonged the engine swap.

I figured i would need to change the mount again when i fix the broken exhaust manifold bolts if i don't get to it soonish.

Yeah, New mounts are the way to go for sure. I wanna drop the diff at the same time and change the oil pan gasket.
