Using one oversized piston with all others of "normal" size is not a problem. In fact, the factory used to do that quite often in the old days before the machining equipment could make very consistent bore diameters and piston sizes.

It was NOT uncommon at all to find engines straight from the factory with oversized bores on one or two cylinders. They would mark it with special punch marks on a certain spot on the block (described in the FSM) that would clue the technician working on the vehicle to the other-than-standard bore diameters. This was also done for main and rod bearing sizes as well.

It's rare for this to happen nowadays, since the machining equipment at the factories generates MUCH more consistent dimensional parts.
Thank you for this. Now I know!

One more question. Looking back over my engine I seemed to have forgotten a vacuum line. Can anyone tell me where this goes?

For my 93, that's where my line for the fuel pressure regulator goes, as well as a line to the charcoal canister.

Do you have a picture of where the line runs too?

Are you using the app? I'm able to upload via phone.

Also, the google doc needs permission to view

Yeah, I'm using the JeepForum app on android. Just tried uploading from the computer and got the same message. Not sure how else to upload pics. Hopefully you are able to see it, I made it available to you.

Got it thanks. Your engine is unbelievably clean


I don't ever remember taking off a hose like that from my old 4.0 ill have to take a closer look in the AM to see if I can pinpoint the connections. Do you have A/C?

Haha, thanks. Probably because it only has 1,500 miles on it. Your set up will be pretty different than mine. Might want to wait for someone with a similar year to chime in.

And yes, I have A/C

Anyone else want to chime in? Are the intakes from a non A/C model different from the A/C models?
