I don't know what a timing valve cover is. That is what the OP stated in his first post.

The current problem is that there is a slow leaking that is hitting one of the spark plugs. I can't remember which seal it is, but the mechanic said it would probably cost $5-6K due to labor.
Would it make more sense to have the work completed in light of the repairs we have already made, or should I purchase a remanufactured 4.4 engine? I have seen a couple on EBay for $3.5-4K including shipping and come with all the needed gaskets, thermostat and water pump.
What would it cost to swap the engines? Would a new engine be too much power for an older transmission?
Thanks in advance!

Don't think the original poster is a mechanically car savvy guy. He didn't notice the blue smoke while inspecting the X prior to buying it. This condition didn't just happen over night. Another reason why one should get a PPI by a reputable mechanic before buying a X or any car that is expensive to repair.
