Ok, so I'm going to post here and use my status as an honorary Midwesterner to ask you all for advice.
Today my KK threw a rod
(or at least that's the preliminary diagnosis). It still idles but it sounds like the squirrels in there are on strike.
I may need a new motor.
My questions are:
What is a reasonable price range for a new motor, and what kinds of places should I be looking? Junkyard or Remanufactured? Pros/Cons?
What years are compatible with the 2008 model year?
How many hours of labor are we looking at for a shop to do the swap? I am thinking $2,000 for the motor and maybe $2,000 for labor, but I don't know if I am in the ballpark.
If I had a garage, an engine hoist, and the rest of the tools I need, I'd learn how to do it myself and follow 2BobsKJ's how-to, but for now I am looking at having my shop do it. It's my daily driver, so I need it back ASAP.
No jeep for a time while this gets sorted out.
Looks like I will be going to work on the train on Monday morning!
So sorry to hear!!
Don't know for sure what model years will work but I would expect an '08 or newer 3.7 will work from any Chrysler product. Generally a Jeep engine will be more expensive - that's been my experience. If you find an engine from another Mopar vehicle you'll probably need to swap things like the oil pan, intake and exhaust manifolds and maybe accessories like the power steering pump. The computers used in the different vehicles will be the same as the Jeep as long as they're 2008 or newer therefore you won't have to swap internal parts.
If you're a diligent shopper you should be able to find a motor with reasonable miles for around $1500 or so - and like I said above, one from a non-Jeep vehicle will be cheaper most likely. That said, if a shop does the work they'll have to swap some parts over if it's not from a KK so you may lose a few bucks on the labor meaning your cost may equal out depending on your shop's labor rate. May be a good idea to talk with your mechanic ahead of time to help you decide which engine/vehicle combo to look for.
Hope this helps - and by the way, have a shop diagnose the engine noise for you. I'd be surprised if the engine could still turn over with a thrown rod. May be something in the valve train like a thrown rocker arm. That's not an unusual problem in the 3.7.
Let me know if I can help!
