Just like the title says. I PB blasted the heck out of it and tried heating it up with the engine on but got burnt. How'd you guys get at it? Top, bottom, what kind of extensions? Anything, thanks.

P.S. passenger side of LT1 = teh suck

 

I got it from the bottom, it was pretty hard, get the 02 sensor ratcher attachments at autozone, they are free loaners. U will need some of those, pb blaster, and some leverage on the ratchet to crack it. I used a hammer, and hit the ratchet to crack it. It is pretty hard tho good luck.

 

i just put a grip wrench on it..got it nice and grip/tight and yank the shizzzz out of it..use some pb blaster and soak overnight..lock tight the new threads
