Is the first step in deciding to do a timing chain replacement, measuring the existing tensioner? Other than the "death rattle" is this the most effective way of seeing how far along it is?

Your local mini dealer would tell you there is a free recall that can be done to fix said issue.

Happy motoring
remember to check your oil

 

Free recall? Not when I had mine replaced. I had to beg to get them to cover half. Only cost me $750. The first thing they do is check how far gone the tensioner issue is which seems to be what TS is referring to. There is a Bulletin out on this. If you're within the tolerance a new bolt is a simple fix. This is what I tried to do with mine (only $50). Unfortunately my used mini already has this done before I bought it. Keep in mind this is really only a temporary fix it seems. Main thing is keep plenty of oil in the engine.
