I was thinking the same thing its a chain and why would the dealer let him drive off with an oil leak

I never heard of a timing belt ('s a chain actually = metal) "skipping", this is insane. If true then it might have to do with improper tension/ chain tensioner improperly adjusted. This is highly unlikely to go unnoticed. Same applies to belt drive. Both scenarios pinpoint in the same direction: bad and incompetent service/ vehicle not properly maintained.

Take what you can gather and contact BMW of NA for advice and a 3-rd party for a second opinion.

PS. Real OEM shows a complete N54 at ~ 11k, not sure if this comes already assembled or not.
