Remove Exhaust Manifold GM Chevy Tahoe Vortec Engine LS Video 7

This one exhaust nut took days to get off. I had to grind it down to nothing to get it to finally fall off.

Notice the side of the head. I had 2 exhaust bolts break off into the head. These are the things that set you back hours on your GM Chevy Tahoe 5.3 Vortec LS Engine teardown

Removing the exhaust manifold, what could go wrong?  Well, mine was the tale of two extremes.  The passenger side was straightforward, quick, and easy.  A few bolts from the head and 3 from the Y pipe.  Total time, under 10 minutes.

Finally got the Exhaust Manifolds out on my GM Chevy Tahoe Vortec Engine LS

Driver’s side:  I rounded one of the nuts from the connection at the Y pipe,… short story –  it took days.  But I finally got it.  Also on the driver’s side, once I got the Y pipe separated, for some reason, I could not get the exhaust manifold past the steering shaft.  I watched endless videos where people did not have the problem, (or edited right past the problem), but I definitely did.  My solution is in the video.

Biggest take away: Hit the exhaust manifold to Y pipe bolts with penetrating blaster and let them soak overnight before trying to get them off.
