Like said in the quote-Sleeving is a simple repair in theory but I don't find it's all that easy to execute in practice. I find it pretty stressful as there are a ton of things to take into consideration. Things like step height at the bottom, final bore diameter for proper interference fit, sleeve material and thickness, is the cutter going to cut over/under or right on target on that final pass, does this repair warrant using Loctite sleeve retainer, can I get the deck perfect without the need for resurfacing? I almost always pull it off but I don't find it all that "simple" to execute. Sleeve a Subaru and machine the wrist pin access hole correctly and get back to me. That being said haven't seen an outright failure with a sleeve repair job and that includes other shops' work. J.Rob
