The PCV is not working as I am experiencing a huge increase in oil consumption so I am replacing that too. While that is out replacing the intake manifold gasket.
Lastly the fuel pump is on the fritz. Going to get a fuel pressure test first.
If that needs changing is there anything else anyone can suggest? The lifetime fuel filter maybe?
Thanks in advance.

Perhaps this list of my maintenance/repairs will help.
On a regular basis:
> Rotate tires, inspect pads & Rotors, CV boots, general look over every 5000 miles
> Oil / Filter change every 8000 miles
> Brake fluid flush every 30,000 miles
> CV Boot replacement generally every 75,000 miles
> Replace belts and clean CCV every 100,000 miles
> Replace differential and transfer case fluid every 100,000 miles
> Replace sparkplugs every 120,000 miles
> Replace expansion tank, coolant and hoses every 150,000 miles
> Replace brake pads every 163,000 miles (Akebono ceramics)
> Replace rotors-once at 63,000 miles (315,000 miles on current Brembos)
> Automatic transmission fluid – leave it alone in the GM 5L40-E
My unplanned repairs have included:
> Front axles at 60,000 miles (Prior owner didn't maintain CV boots)

> Air injection check valve at 377,000 miles
> Front brake tension struts at 378,000 miles
All in all, except for the front driveshaft job that cost $4200, I have really been happy with the vehicle. It doesn't get babied, but I do monitor and maintain it. I think a lot of my good fortune is due to four things: I live in Texas with short winters so I don't have a lot of the CCV condensation problems, my daily commute is 60 miles so the engine oil always reaches full operating temperature, I run the "M" series viscosity engine oil from May through September when I my driving includes 3000 miles of towing a 1400 pound Waverunner and trailer, and I stick with Shell gasoline.
I do believe I’ve figured out what goes on with the thermostat failures. Each one occurred within days of an extended idling period (3-4 hours) while commuting home at a crawl during very cold, icy weather. Under these conditions, every bit of engine heat was consumed trying to keep the windshield clear and the interior warm, so the engine thermostat would have been powered to stay closed or nearly closed most of the time. I suspect a higher current flow to the thermostat for that amount of time simply “burned it up”.
