Yeah, I heard of Kroil and LE and would much rather use that stuff but the PB Blaster was what they had on the shelves at the moment. I've heard of guys separating the housing in just a couple of days. I think mine was the
worst case, the PB stuff did work though.
Also, I bought a gallon of kerosene at the hardware store to break up the carbon on the inside of the housing . I soaked the whole unit in a bucket. 2 weeks of that and it was still
WELDED. A bunch of carbon chunks came out though, so I knew I could spray PB on the inside joint.
I shot the PB into the housing using the red sprayer straw. And just tilted it around then put it back into my huge vise and would go to work. Then later, I'd shoot it again, and also give it a few test wacks.
Hammer didn't work. My
deadblow hammer did nothing. I used my mini-sledge (bigger BFH) and hit it all around. DON'T crack the cast housing!
Tip: you also have the Holset so be sure to leave the retainers bolted in place but a little loose. This will keep the Turb hsg from flying off and bending your turbo shaft. That thing is DELICATE! Do not bend.
So about 6 weeks later, I routinely wacked the housing and all of a sudden, I could see a micro-budge. Flipped it and hit the other side.
Then, it just slipped off. Super happy but kinda disappointed...
I almost could not believe I WON!
I was soo pissed before.
(I'm in my happy place now).
Now I can rebuild and plan to rotate to align with my custom manifold
Good Luck. Yours may come off right away...
