you can easily check it if you remove the drivers side valve cover.
also check the inside of the valve cover for chain marks.

he's right. the lh cover will be scarred on the inside. chain breaks at the wrong speed and it'll break through that cover. 75k for a loose chain is not unheard of. in the old days, you come in for an oil change 4 times a yr, we'd charge extra to pull that cover at some point and check the chain. seen them break at 90k but more often 100k to 120k.
replace the tensioner with mb part only, do the upper guides and chain at the same time. iwis for the chain, febi euro, if you can find it, is ok for the guides. there's some febi coming out of china and i wouldn't trust it.
