Technically yes, but you'd have to set gears up again.

How important is it to change the o-rings on the fuel injectors when swapped over to a new motor? Will this break the seal and cause air to leak in?

Al I needed to know lmao. No fuel leaks whatsoever! But I'm having a fuel delivery problem at idle. Drives and runs fine, but after some research and asking around I'm thinking since I did not replace the o-rings during the motor swap that they are letting air in and causing a nonconsistent Idle. Everything else is new and in good working order. That's why I'm looking at those o-rings as the culprit...

Bad seal around an injector that could cause idle issues but NOT a fire would be on the side in the manifold. In such a situation you'd be looking at a damaged or hardened O-ring, or you didn't clean out the manifold holes before reinstalling (common). At any rate troubleshooting is easy as it's just a vacuum leak. Shoot some brake cleaner around and see what happens.

What would cause coolant to leak out the rad cap? I have a leak and it "appears" to be coming from around that area, but I'm not 100% sure. I put my old cap on and I'm not going to make any other changes just to see if i just got a malfunctioning cap 😕

The overflow tank line. That can leak. It's goes I. Right below the radiator cap and I've mistaken that leak for a radiator cap leak as well.

The very early XJs are pretty rare here. I recommend starting a proper thread to get some more eyeballs on your issue
