So im guessing you need a 4.6 motor? I have one for 2500 no ews3 tho. I was thinking about doing the swap into my e39 but, i cant find a good enough write up. Im in need of 2-3 M62B44 motors my self.

Old thread, just wanted to say if anybody reads this - something self experienced, I had this repaired in my own engine:

chainguides are a big problem regardless of M62, M62TU or S62. The old M60 doesn't have the problem though. It stems from the fact that BMW removed a gear when they did the M62 development (cost savings probably), and instead relied on chain guides to do the work of the gear that is in the M60.

These chain guides are coated in PLASTICS. No wonder that plastics breaks with age.

SO: regardless if you get another M62, TU or S62, you will get the same problem. Chain guides need to be replaced around 170 K miles.

That said, it's obvious that TerminatorX5 should rebuild his M62B46.
