LOL, he's going in hardcore with that torch. Recently had to pull off the manifolds on a 2003 Hummer that had been on for 22 years. Used one of those small butane pencil torches.... Doesn't take too much to take care of the factory loctite..... Then with a small ball peen hammer I would tap each one lightly about 15 or 20 times after spraying it with penetrating oil. Only had two or three that I had to rotate back and forth left and right a couple times. Other than that they all came out nicely. But .... It had never lived in the rust belt. I imagine for a shop considering the time factor, the big torch would speed things up quite a bit.... Just seems a bit risky to me.

I do have a nice drill guide that bolts onto the head, and a set of reverse drills. So far they're still sitting unused.

I had 2 broken on my 06 Suburban. I was ready with my welder. I had removed them on engines on engine stand before by welding a nut, but never on an engine inside the vehicle.

When I removed the exhaust manifold, there was plenty of threads so I was able to just unscrew them with vice grips. I bought some Summit Racing bolts that kinda looked like ARP stuff. I think they were like $25.

I really miss being in a shop where I had access to the "hot wrench" and a bigger compressor than a 3 gallon tank. Have to be cognizant of the neighbors. With no rust here, the "hot wrench" not being available is really not that big a deal and the small compressor works for cleaning/blowing stuff out. I have the Milwaukee Tool battery stuff and that works fine. There has been a couple times an air chisel vibrator or cutting bit would have been nice but I worked around it.

IMO, the video guy got real lucky with the small amount of rust he encountered.

I have clamps on 3 corners of the engine and no leaks/noises but when the time comes, I will prep for 2-3 weeks in advance with Aero Kroil on all the nuts/bolts.
