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!

Tough decision you have to make, if you really, really, really want peace of mind you'd probably be better off buying something a lot newer and a lot more reliable. The X5 E53 has never been known for its reliability, especially as they get older, if you spend the money to get it fixed you can bet money something else will pop up soon, have you had other non-engine related problems? I know no one likes a car payment, but I would look at getting something newer and more reliable, good luck.
