Question: can you remove the camshaft on a 3.8 in a 5th gen without removing the engine from the car?

If the crank centerline is about the same as the 4.0 engine and the cam is maybe a foot above the crank, I'm gonna say there's not enough room (length). When I replaced the timing belt on our 4.0 engine last year, I had just enough room to remove the balancer.

I strongly suspect if you were to play the old shade-tree mechanic and disconnect the engine mounts and tilt the front of the engine up, you will be able to just clear the fender as the cam comes out.

I've done exactly that on a 4th gen with 3.8. Pulled the cam out the wheel well. Don't remember the details but I think I had to disconnect the suspension strut to allow the engine to come down and back far enough without the driveshaft limiting the motion. I know it's not the same vehicle but hopefully encouraging.

It can be done. You need to remove the front and rear motor mounts, aside from the right one, obviously. I'd recommend removing the right driveshaft as well. You can raise the engine just enough to clear the fender well. In case you're wondering why the cam and block are dry, I had already removed it and cleaned everything up, before it occurred to me to take a picture, since I wasn't sure I would be believed. The cam is shot after 270k miles, lobes are badly galled. I will be replacing the cam, lifters, and timing components. Heads have been rebuilt. All motor mounts are sheared and being replaced. This engine has good compression and I hope to get a lot more miles out of it.

That's a odd failure for a roller cam.
Hope all goes well for you.
