Seized Pilot Bearing Since it's in the crank, I assume it belongs here...
The pilot bearing in my engine will NOT come out. I used the slide hammer tool and it wouldn't budge. I had a real mechanic (not me, lol) take a look at it and he said he's never seen that tool not work on something.
I checked on search and I found someone hit it with a dremel at 12 and 6, I tried that but the dremel tool doesn't want to cut through it, at least not very easily. I got through the bearing portion, it's about half as think as it was before on both sides.
Any other recommendations?
I'm putting a Viper T56 (with input shaft) in my swap, so I need the old bearing out so I can use an oversized bushing.

The tool didn't work for me, either.
The bread method could work, as long as the punch tool seals the ID of the bearing. Otherwise, you're only going to squirt bread at yourself, through the unsealed ID of the bearing.
A quick shot of nitrous (or, the freeze spray) would allow you to remove the bearing with your gloved finger.

There are more than a few threads on knocking out the oil plug using the bread/grease method.
Use a puller and maybe a dremel.

you have to hit it pretty hard to knock out the oil plug... it installs like a freeze plug...
with the bread... you just tap it lightly... it doesnt take much usually...
and if it doesnt want to budge, then you usually have to cut it out...
if its seized hard enough, it may have gotten hot and essentially soft welded itself to the engine....it will come out.. but you'll have to really gut it down and then break it out in pieces.

i bought a blind hole bearing puller from harbor freight and it worked like a charm. my pilot bearing seized while the engine was running and blew up. it knicked up the bellhousing real bad and all kind of pieces were floating around the clutch assembly lol. all that was left was the outer race and it was completely fubar. that $40 tool set i bought literally took less than 30 seconds to remove what was left of the bearing. i'll never try another method again.
glad to hear you got it removed. that is the kind of **** that's a real pita.

Yeah, just not sure which would bother me more, the metal plug in the oil pan, or the bread in there
