I have a 2004 2.3 DOHC liter engine that had a piston fail, scoring the cylinder. I took the block to a local machine shop to have it bored/sleeved, or whatever it needed. It's been almost two months. The shop ordered a sleeve, expecting something on the order of 90/1000 (3/32?), and got a sleeve that was 100/1000 (give me a little leeway on the numbers, he was rattling them off fast). He sent it back figuring it was mis-boxed. Three sleeves later he's still getting the thicker sleeve, which he still thinks is too thick. He's also not finding satisfaction on why there seems to be a discrepancy and is hesitant to bore out the block until he's sure of the answer.
I'd like to get the block back. What are the experiences of members here on sleeving a block back to stock? What are the correct dimensions? Googling it I'm finding Darton sleeves for what seem to be builds for more HP, not so much just a stock fix. Who has done this before? What information can you share with me to help me get my block back?

Thanks,
Chuck
