[rockola1971]

2005 yukon denali all done this year. Tie rods, idler and pitman arm, spark plugs and wires, valve cover gaskets, power steering pump, power steering pump cooler and associated lines, steering gearbox and line to hydro boost from gearbox.

Hope to have done this year line from hydroboost to power steering pump, hydroboost and install fuel pump module.

I did a bad bad thing...

Air chisel. Else welder.

For what it's worth: you can pop the breather cap out (threaded, twist CCW) and fill from there.

Edit: to add, if you go the welding route, let the ****** cool before trying to extract else you'll rip the threads out of the diff with it.

Is it possible to have the oiling system fail on only one side of the motor? Buddy removed the ds vc and was revving it--no oil was being pumped. He didn't check the ps yet. Is that possible to even happen? Got it up to 2000 rpms. He thinks the hv --GM Performance--oil pump has failed causing damage to the lifters.

Driver's side gets oil first and also feeds the main and camshaft bearings. Change the filter and check again.

Still stressing about the used oil analysis tests showing coolant in my oil. I have also noticed signs of coolant or moisture on the bottom of my oil fill cap, but NOWHERE else. But two tests two YEARS apart showing coolant in my oil? WTF is going on? Could it be such a small amount of coolant that it doesn't quite get a chance to do any harm because I change my oil regularly? Because of that, plus the fact that it's my daily, I'm still driving it. I just hope nothing bad happens before I get the chance to investigate it further. I'm off half a day on Saturday, so I'm planning on taking the valve covers off to see if I see any signs of milkshake oil. Truck still runs perfectly fine, doesn't run hot at all, and the oil "appears" to have absolutely no coolant in it on the dipstick and when I drained it from the oil pan. I guess I need to double check and make sure I don't have the dreaded Castech heads. I could have sworn I checked for that a few years ago when I last replaced the valve cover gaskets. That was around 2012 I believe.

Resoldered the ABS module again today. Two years ago I fixed it and it worked till last Saturday. Two of the big round things were loose solder joints - the two I didn’t touch last time lol. I have ABS again yay

Hey, thanks everyone. My son is coming over to help (technically I'll probably be the helper...) so I'm thinking it will be good. Last time it ran the low fuel light was on so I know there's not more than 4 or 5 gallons in it. I may even run it for a few minutes if it'll start. Still, on jack stands in the garage, it ought to be an interesting experience!
