Here is the deal guys, I bought a 01 X5 M62TU without getting to physically look at it (I know, scary right??). Turns out, like all M62 engines, the timing chain guides are destroyed. It ran/idles really rough. Would not really rev and misfires when trying. Dies about 30-45 seconds after running. And sounds horrible (most likely due to the chain guides). Lower oil pan was dropped and the valve guides are in pieces and the oil looks like there is glitter in it.

In my impulsive nature, I ran out to the junkyard and found a 5 series that was DRIVEN in to the yard and pulled it. The oil looked good. Both good indicators. However, this engine is a non-vanos (M62B44).

My question to you guys would be, what do you think I should do? Just refresh the TUB44 (all gaskets, timing chain and guides, s. plugs, etc.) granted the valves have not stuck the pistons. Or get the vanos heads rebuilt and slap them on the B44 (with the electronic throttle body and intake of course)?

I haven't done anything to either engine except drop that oil pan.

Thanks again guys. This is my first BMW. Hope it doesnt like a salty taste in my mouth.
