Keep Sinking Money or New Engine?

Check again and see if the mechanic is not talking about the valve stem seals and not valve cover gaskets. Your X5 has the N62 engine known for valve st seals issues

That was my thought too. He didn't say it was the valve cover gasket and could very well be talking about worn valve guides, especially since he said the VCG had been recently replaced.

IDK, all that work, including a *timing chain* at only 100K?

He didn't say the valve cover gasket was replaced, he said the timing valve cover was replaced. Since he mentioned timing chain was replaced I assume the timing cover gasket was also replaced. He mentioned oil in one of the spark plug so I assume he was talking about valve cover gasket. He didn't say that his car was burning oil.

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.
