Large bent-nose vise grips - do they exist?

[old_smokey]

I am trying to pull a seized inspection cap out of the back of a motorcycle engine while in the frame. It usually has a 17mm nut cast into the cap, but it first rounded off, and then snapped off entirely, leaving the rest of the 1.5" diameter plug in place. Problem is, the cap is threaded into a recessed section of the engine, so I can't lock a normal set of vise grips onto it.

I have been searching for some kind of tool that can reach into the recess and lock onto the cap. I have bent nose needle-nose pliers that are the perfect shape and offset, but don't open enough. I've seen small vise grips with a bent/offset jaw, but not a larger pair

Anyone know of a tool that might save me from pulling this engine out?

use a chisel on the edge to turn it.

I have a pair of 9" bent nose vise grips, bought a few pairs NOS a few years ago, 4BN, 6BN and 9BN. So they at least made up to 9" ones.

Tried that. It just starts to break up the cap, and I don’t want the little bits falling into the engine.
