I just picked up a blown xj from the ole craigslist for $1500 and towed it home. I have already started taking it apart and getting ready to put a junkyard motor in it. Here is the craigslist add, and a picture of the engine as it sits getting ready to be pulled.
I will get more pictures once day light hits, and update the thread if anyone cares. Now onto the question that has been bugging me. I have done my research or tried to anyway, and the exhaust will most likely be different from the engine I pull from the junkyard. So How exactly do I get say a 96 engine with a 96 exhaust manifold to work? I know mine has cats and a different ports ect. But I don't know what to do about the 02 sensors ? Anyone have any insight to this?
I have 2001 Jeep Grand Cherokee (Limited). This past winter I was in a similar situation. I took an engine from a 96 and put it in my Jeep..... Im not sure how things are set up in the 2001 Cherokee but if its the same as a 2001 Grand Cherokee, you may have a lot of work ahead of you. Does your Cherokee have 2 catalytic converters? You may have to use the manifold from a 2001 Cherokee. I had to keep the manifold that came with the Grand Cherokee but the ports on the 96 head are larger. The manifold from the 2001 is not going to match perfectly so you will have a small amount of exhaust leakage. This will effect your O2 sensors and performance. A tube header instead of the cast iron manifold for a 2001 is expensive but may work better. Also, my Grand Cherokee has 4 O2 sensors. The 96 did not so i could not us the 96's exhaust anyway. There are a few other things such as the pulley and accessory arrangement that may be different too. I know that the A/C is mounted differently on my Grand Cherokee. This led to some.....'creative engineering' on my part. The motor mounts did not match up either.... more work there too..... Anyway good luck!
Today I started pulling the new motor, we filled it with oil and tried to start it with starter fluid and jumping the starter with a screwdriver. No success with starting it, but it turned over nicely so I have faith it will run.
The back of the motor has a nice new shiny freeze plug, and a semi new exhaust manifold, could anyone verify a way to find out if this a rebuilt motor by chance? It also did not have the top 2 etorx bolts on the transmission, so I have reason to believe it has been out.
