Whats the chancez of....

Snapping a spark plug off in a 2.9 head?

Im getting a cold missfire and a slight warm missfire under load. The plugs/wires/cap all look to be very old, possibly original (87 2.9).

I know ive reefed on plugs before on the V8 motors, so i dont see why a 2.9 plug would be any less resiliant, but im wondering whats the likelyhood here?

i have blown a few porcelains out, but they usually let the bodies out of the hole with a wrench......

If your that worried just soak the heak out of them with a 50/50 mix atf & mineral spirits, preferably overnight before you pull them

Yeah ive broke alotta porecelain, i dont give two shits ahout that.

Atf and mineral sprits? Dont think ive heard of that one. Ill try it though. After the cluster F my brake hose replacement turned into yesterday i really dont need any more headaches.

I'm pretty sure it's ATF and acetone.
