1fz Stuck flex plate bolts

[Scrapedknuckles]

Hi all, so I've tried impact wrench, propane torch, extractor sockets, multiple breaker bars etc.. I have been able to get 5 of the ten bolts out but the rest are impossible to move. I know trying an EZ-OUT is just going to snap off. The engine is out of the truck and I'm out of answers. Have any of you had similar situations? How did you get the bolts out? I've heard of the wax trick but it seems to be myth. Thanks Eddie

I have always had luck with kroil, sometimes I will spray it let it soak then hit with heat gun and get the oil smoking, 400 degrees or so, then hit with my 1/2 electric snappy impact gun let it rattle for bit then give it the beans. If that didn’t work I would put a 3/4 impact on it.
What is the wax trick?
Has it been pulled in the past? Maybe someone red loctited them in? Those get torqued to 74 lbs in passes so shouldn’t be horrible.
