I put truck on a lift . It's not that bad as I thought. Some frame rust. But I don't think that's something that will require emergency repairs.
Transfer case seal. Exhaust leak on a joint before muffler. Could not take a look under the engine cover. I will drop it off on Monday again to eliminate some of issues. Step by step we are getting there. Changed oil to this. I looked up, it was AC Delco filter and Mobil 1 full synthetic oil before. I did on that oil maybe 500 miles and it turned black. Let's see on this. I will drive for 1 k and then change it again. Our shop mechanic said that pressure of 20 is good.

Who knows what size is this bolt. It's from intake filter. They all are rusted. I had to use chanalock to unscrew them.

Is that from the lid to the lower air filter box? Or some other place?

Yes. It is.

They’re special, not something you can find in a hardware store. Amazon carries them.

No my are completely different. I have a threaded insert. It's some m bolts. I have no replacement for them . I might have few titanium in my van
We use them for Elevator brake adjustment. I will check them out. I ordered that thread checker from Amazon. I think I will have to replace lots of bolts under the hood. And I will definitely find a use for it. Unfortunately I parked my truck fome 5 blocks away.

Home improvement stores, as well as ACE Hardware, would have thread checkers for both SAE and metric in the screw aisle.

You can also imprint slightly dirty threads on a sheet of paper and measure how many threads there are in an inch. Measure the outer diameter with a caliper to determine what size, and if SAE or metric.

I faced another issue. I bought nice looking tail lights. And I didn't know that plugs do differ. Now I'm screwed. Can't return them and I don't know wiring diagram.

Why can’t you return them? Looks like you bought them on Amazon?
