I need to separate the front section of an exhaust from the manifold.
It's held by four M10 nuts that haven't been loosened in many years, if at all.
Applied PB Blaster a couple weeks ago in preparation. Applied some more overnight.
They won't budge, using only (non-impact) tools.
Applied some more, tapped it with a hammer. Tried heat with a propane torch, and quick quench with some water. The only trick I haven't tried is candle wax.
I don't want to snap the manifold studs and have to replace them as well (they're tack welded in place), so I decided to quit while ahead.
Thinking about taking it to a pro (exhaust shop) and having them break them loose for me. Impact, hotter torch, experience; I expect they can do a better job than me.
