Since you only have the problem with the left bank, I would rule out machining errors like valve face to parting surface depth. The only other possibilities would be incorrect VALVE timing, malfonctioning chain tensioner, or stretched chain. When a stretched chain on an MB V8 starts whipping, it breaks the plastic guide on the left bank which climbs up the chain and causes the cam gear to slip on the broken piece of plastic. It's a classic problem. It happens all the time. Every 47 minutes this happens some where in the world. Even though you replaced the chain, what is the quality of the part you bought? If the chain is ok, I'd look at the tensioner next.

Good luck,
