Hey all, I have an 07 with a blown head gasket and the engine has also always been an oil burner, has the spark knock issue, and the water pump is leaking, not to mention an oil leak (thinking rear main but not certain). I am working on getting a used engine that doesn't have any issues, its left over from a hemi swap.

Anyway, how long do you think it would take to pull an engine and put the replacement back in? I haven't done a swap before. I did pull an engine out of a truck in an evening but we were just clipping wires without any cares.

Thanks for any input!

Have you not taken it to a dealership to try and warranty out the motor? How many miles on it?

It's an easy swap

schedule a weekend for it, get most of it done on saturday, finish the little things on sunday then break out the beer and fire up the grill to feed the help. (This will also work for most things that you need help for)

Thanks guys, it doesn't look like a really tough one but it is uncharted waters for me.

The jeep has nearly 60K miles, dealer thinks it is my problem since the warranty was up at 36K. They did offer to take mine in as a trade in and sell me a new jeep.

I was going to have the head gasket fixed but then I would still be stuck with an engine that makes me wonder. So, if I can get a decent engine I might come out ahead and have a jeep that isn't an oil burner.

A couple days isn't too bad! I will need to track down an engine hoist but that should be easy. Think it is easier to pull the engine and transmission or just pull the engine? Once the grill and radiator is gone it should slide right out.

Had a motor with a spun bearing replaced with a rebuilt long-block in a vehicle a while back. Left the car in to the shop at 8AM & picked it up at 4PM that same day & in that 7-8 hours they removed the old motor, removed all the stuff from the block that they would be re-fitting to the new motor (carb, manifolds, oil/water pumps, timing cover, starter motor, alternator, etc), and then re-fitted these components to the new long block & then re-installed it in the vehicle.

Taking that the guys that did all this were trained mechanics and engine re-builders and had probably done hundreds if not thousands of engine swaps in their lives, I'd allow 2-4 times as long at least if you haven't ever done it before. So yeah as others have said, give yourself a whole weekend including a few late nights. If the replacement motor comes complete with all the manifolds and ancilliary equipment it will simplify things a lot as you won't be spending time removing all these components from the old motor & re-fitting them to the new one. Just make sure you do plenty of research first and lable all the connectors and vacuum hoses (take photos of them prior to disconnecting them too so you have a visual reference as to where they go).

As for pulling the tranny, if yours is a 6-speed then you may as well replace the clutch while you're at it.

Hey Bryan,
If I'm not working, I'll help. It shouldn't be too bad. Just call me. I'm cheap, it will only cost you a Dr. Pepper or 2.

Sweet I will take you up on any help you can give. I was gonna talk to you tonight but you were a no show.

Just waiting to hear back on the engine.

Have not done a JK but did my son's XJ this summer. It was our first engine swap but we had help from an experienced guy. Air tools made a big difference under the jeep, especially with long extensions to get at the bolts between the engine and tranny. X2 on doing your clutch while everything's apart. Plan on a weekend and a few nights.

How long? I say "long enough" to have 8 cylinders
