M62 Vanos chain tensoner question

Hello I have a strange question for you pros. I looked at a 03' X5 4.4 the other day that will not start just cranks. While it cranks there is an audible rattle coming from the left front (drivers side) of the motor. I have done timing chain replacements on other M62's but those vehicle's ran and rattled all over.. My question ultimately is has anyone had a cam chain tensoner collapse? I have seen them go on Audi 1.8 turbos and they make a hell of a racket. My rookie theory is the tensoner on that side has collapsed and ultimately thrown out the cam timing... Thoughts? I am unable to remove the cover and inspect due to the vehicle is for sale and I am considering buying it. Thanks for any direction.

if you can get another crack at it
just take the tensioner out its a 19mm

somebody i once read loaded theirs with dimes or something
they even stated how many

i wouldn't do it ... at least for any serious amount of time
but if you have any doubt you can try that for free

Well missed out on the X5 so guess I won't be able to check my theory. Bought a 00' sport instead. Thanks for looking guys.
