Unpopular opinion: a dab of anti-seize on injector threads is a game changer for old farm equipment
Working on a 30 year old John Deere tractor last month, the guy said he'd had three mechanics walk away from the stuck injectors. I was about to do the same after snapping a socket extension. Out of pure frustration, I heated the area with a torch for about 90 seconds, let it cool, then put a tiny bit of copper anti-seize on the threads of a new injector before gently working it in and out. It acted like a cutting paste and cleaned the threads enough to get the old one out. Saved a full day of drilling. Anyone else have a weird trick for seized parts in aluminum heads?

It's funny how the best fixes often come from a moment of pure frustration, not the proper manual.

Right? The manual is just there to make you feel dumb before you start hitting stuff.

Wait, that's a great trick but careful with the torch on aluminum. It can get too hot way too fast and wreck the head. I've had way better luck with a good penetrating oil and just letting it sit overnight. Sometimes even a mix of acetone and ATF works better than the store bought stuff. Heat can be a last resort, but you gotta be real gentle with it.
