Well long story short we blew the engine consensus is its probably a piston. 1st question how hard is it to pull the sleeve, I have read that some have to be milled out and also read heat the block up and sleeve will come out. We are not rookies to turning wrenches we know what a crescent wrench looks like LOL. Anyhow I was also told only one place to get new sleeves and that was darby performance out of fairbanks do any of you know of any other places in the lower 48? We are not looking to bore it out just put it back together using OEM part ie piston, sleeve thanks.
