not all of them and it it gets too hot it will just liquefy. You are better off with wheel bearing grease. if ghetto has a turbo, they wont pass freely at cranking speeds, or any speed. Damage can occur from them not totally passing and then wearing on something down over time. if its NA, you have nothing to worry about.

If its an ATS system (or stock) just take the crossover pipe off first. Its only 4 bolts and drops right off. Then drill and tap the hole in the driver's side manifold by the last cylinder. Start it up for a minute to blow any debris out, then put the crossover back on.

That's what I did with the banks turbo, I just dropped the crossover and tapped the hole like 6 inches away from the flange. Temp is very responsive and probably just as accurate as drilling the manifold.

Its not very clear how I wrote it, but I meant to tap the manifold while the crossover is off. I think I took a picture of mine when I did it, but can't find it now. There is enough room to easily drill straight up into the manifold from the bottom.

Why number 8 cylinder? Think about which of your cylinders will produce the most heat...this will give you the best readings!

No gasket, just the pipes flare seals against the manifold.

As far as rusty bolts... exhaust bolts are notorious for rusting something awful. However I was extremely surprised that mine came off no problem when I put the turbo on last year. I didn't even have an issue getting the studs out on the passenger side as needed. Maybe I was lucky, or maybe these trucks don't have as many issues as every other vehicle I've worked on the exhaust.

Make sure to soak them liberally in your favorite anti-rust chemical for a few days first.
