I'm doing a complete overhaul on my '87 Wrangler, 4.2L engine. I took the block to a machinest to have the cylinders bored out, since with over 200k miles, they're too worn in to just hone. To 'cut' a story short, he calls to tell me that his machine threw a blade, damaging my #1 cylinder and destryoying my #2. He assured me that he will take care of it by installing 'sleeves' in these two cylinders. He not only adding 4 days to the job, but now has me concerned regarding the integrity of the completed engine. I plan on driving this baby to 500k and want to know if these sleeves will make that more or less likley.
