Ok, here's the post where I ask what else I should do when I have both diffs out. For the back, so far it's just the evap charcoal canister. I've read too many posts here lately about those failing so I bought a GM OEM and have it now, will install this weekend. (I know it's probably not much more difficult, if at all, to replace with the rear diff in, but I've got it in the air, spare tire out, tools out, etc. so best to get it done now) I was also going to do rear shocks, but there's no sign of leaking and they appear to have the proper damping action, so I'm holding off for now. Pretty sure they're GM, but not original. My rig has 200k, I don't see how they could be original.
OK, so now for the front. Original plan was to drop the pan and do the oil pump pickup o-ring and new pan gasket. BUT..... my oil pressure seems good and the very small amount of leaking I get seems to be coming from the oil cooler block off plate - I know those gaskets fail over time. More on that in a sec...
Here are my typical oil pressures: hot idle, about 18-19 psi. 1500 rpm, 35 psi. 2000 rpm, 38-40 psi. 2000+ it doesn't go much higher than 40. Any concerns with any of those values? I just don't think it's worth it to drop the pan at this time if they're OK.
Regarding the oil pump cooler block off plate gasket. But, I had long range plans to add the OEM cooler lines and replace the radiator with one with that functionality. Worth it to just add the oil cooler now? To sweeten the pot: I actually already have the lines. I would just need to drop the $200 or so for the new Denso radiator.

Last question is about the motor mounts, especially DS. Is there anyway to check them for signs of impending failure? Looks OK and very clean up there to my eye, but I've read about many failures.![IMG_5845.jpeg IMG_5845.jpeg](https://www.tahoeyukonforum.com/data/attachments/428/428578-ef7aafbc86ae663fbd756cb08a09b267.jpg)
