I took my jeep to a mechanic last month because there was a rod that was out of place so it was knocking, I still haven't gotten my jeep back because now they are telling me that the timing is off on it and that wasn't even a problem when i took it to them I've already had to pay about 1500 to fix and repair the engine, and that wasn't even to the guy i took it to the mechanic i took it to wants to charge me another 1200 for what little work he did, so my question is How much and how long does it take to fix a timing chain/ belt? and should i have to pay for the mess up they caused?
I need to know exactly what they intend to do on the engine, you are just to vague.
Testimonial: "Well they told me just a few min ago that the timing is off and they need to take the engine out and fix the timing he didn't tell me if it was the chain/ belt but i think it might be and he said that it would take up to 6-8 hours more to do all this I'm just getting really upset cause like i said they have had my jeep for a long time, they never really give me much information on what they are going to do. Do they really have to take the engine out again ?"
Then it must be the valve timing.

First, I'll tell you what I used to tell customers that did this: Do you bring your own uncooked eggs to the diner?
The cost will vary... each shop charges a different labor rate. Without encountering any unforseen problems, I doubt if the cost will be more than $140 (excluding antifreeze). But, when approached with this while running a shop, I used to also add the "markup" I would have made on the pump as well... after all, why would a shop want to do the same job and make less than they would normally??? So if they charge you 20 or 25 more $, dont be surprised!

If you have the same pulley arrangement that most 4.0 engines have that pulley is an idler not a tensioner. Your power steering pump has a pivot bolt, and a slide under the pump. You adjust belt tension using the pump.

Can't tell you exactly what is wrong but the one thing you said is of concern...Map sensor should not be full of oil. If it is, I'd want to know why. In finding the reason for that, you may also find the reason why you are having a problem.
Jeep uses two kinds of engine crank venting. you either have a pcv valve or an orifice controlled system. If either are obstructed it can overpressure the crankcase and cause all kinds of problems.
Years of experience tells me this isn't something I can guess at and be 100% sure I have the right answer but based on what you said, I'd look there first!

I BELIEVE THAT IT HAS A TIMING CHAIN. IT SHOULD BE CHANGED AT OR ABOUT 100,000 MILE. BUT IT DOESN'T NECESSARILY NEED TO BE CHANGED THEN, JUST INSPECTED.
