New Engine Options

Looking for some advice on my 2001 Limited 4.7. Not 100% sure what happened, but I just left the shop and my guy says that the knock is low in the motor, damage has been done, and will need a new power plant. He is going to call around tomorrow and see what he can do on pricing of a used motor. He will install for $600 cash. I have been looking on line and see that the Durango and Dakota also run a 4.7L V8. Are these actually the same motor and can be bolted into the Grand Cherokee? Any advice would be appreciated.

This might get frowned upon by other users but if you have the money go with Jaspers. Get a completely new engine. Its costly but used engines have that potential to be unreliable. Once my 4.0 dies (which might not be in my lifetime <sarcasm>) Im going to see if I can have Jaspers make me the 4.2. If you are seriously considering Jaspers but want a v8 go with the 5.3 instead of the 4.7. The 5.3s run forever. Hope this helps.

You can also check www.car-part.com. many recyclers will give a short warranty and will have checked oil pressure and compression.

I actually stumbled upon car-part earlier this morning. I found 2 used motors within pickup distance. One at $1000 with 158k and one at $1200 (still waiting on mileage and confirmation that they're the same motor) From what I was told, a 4.7 from either a Laredo or a Limited will work as long as the new motor has the same 16 tooth tone wheel. Can anyone confirm?

I just went through an engine swap with my brother. He has a 2004 Limited.
You are correct, just make sure the number of teeth match what you currently have. Make sure you visually check the number of teeth and make sure both are the same....

Look for my thread from about 2-3 weeks ago as I also had a dead engine. you will see a number of references for remaned ones. Remaned + install+ new 'recommended' parts (e.g intake manifold) would have cost me in excess of $4500. With my situation, this was too much $s for a 10 yo vehicle. I found engine from a 2001 with 89K miles that was backended, for $1600.
Cost to install is $1100.
At the moment, replacement engine is in, runs fine, cept oil pressure light goes on occasionally...new sender did not fix problem. prelim info from garage is that a wiring change in engine harness has to be made - we shall see.

Good luck!

I agree with the thought that putting a used engine is a gamble not worth the savings. I priced it all out also when my 4.7 died last year and ended up buying a Marshall reman through rockauto.com like this:
http://www.rockauto.com/catalog/more...936&cc=1381452 its $2800
They delivered to my house and i used a online coupon code for 5% which made the shipping free. they also accepted my used engine as core even though it had exploded parts inside. have had zero probs since then. Jasper also makes good stuff but in this case of stock replacement i would not bother as they extra cost they charge is not really going to do much for you in the long run.

Great point. Im not a fan of the 4.7s so getting a used one would set red flags up to me personally. Looking back, if you could get a used 5.3 I think would be better than a used 4.7. But I dont know if the WJ can fit a 5.3. Does anyone know because that will be interesting to find out.

by "get a 5.3" are you referring to swapping in a GM LS series engine? you are not being clear about that and its certainly a great idea but not at all what the OP was asking about at all he wants opinion on buying a used 4.7 versus something else like a reman. Thats straight up custom work not something a local garage is going to drop in for you for $600 not sure why you keep mentioning it. Why stop there why not install a LSX 454 with supercharger?

5.3 Magnum. Can still keep it Mopar. And i would love to install a LSX 454 but it wont fit. If the 5.3 fits Id rather have that then the 4.7. And I was simply suggesting because some others like me dont like the thought of used. Not saying it is bad but other people prefer new. I was simply adding an option.

You must be talking about the 5.2/318. This has been brought up many times before and while it may be possible, it certainly won't be cheaper than a reman'd 4.7.

[powertrain is also a good company. I have never dealt with them but my father has dealt with Jaspers and had them build a 351 for his Bronco since he didnt have the XLT. Non XLTs came with the 302. A 302 in a Bronco -_-
