Completed the work on my tahoe
new O-ring installed
New pan gasket
oil pressure bypass in the pan has been replaced, and a deflector added.
Added an oil pickup tube support (I didn't cheap out, but probably should have).
New front axle mounts installed while i was in there.
I pulled the crank plate thingy, took a flash light to look at the cam bearings.
I didn't go crazy detailed with it, but everything looked great.
And i changed the oil pressure sender, and the screen under it.
The screen looked surprisingly good.
I was expecting crud in there...
Fresh fill of oil... ran the engine.
Not much change.
Oil pressure seems a bit more steady, but the gauge still flutters a little.
It's maybe slightly higher hot... (or i'm just telling my self that to make me feel better).
Driving it, better pressure rise than before, goes over 40... it seems a little delayed tho.
I swapped oil filter brands for why the f not, no change.
Maybe it's something with the bypass in the pump it self?
I did look to see if i could get to the bypass to clean/inspect, but it's blocked by the front cover.
Calling it good enough.
I have AFM disabled, and its plenty high enough for a non DOD/AFM engine IMO.
Still odd that it suddenly dropped...
....what did I do to my GMT900 today... I wanted to fix it but this happened:
The deed has been done, sir.
already thinking about that cam swap/full DOD delete.
I figure if i need to pull the front cover and pan again, I'm going all in.
Looks like the piston took a break from hard work.
Do a 6.2....that engine is toast...
He did have a 6.2.
