the faulty timing chain tensioner
#4
You can't really tell by looking. Is the spring tension correct, is there something else in the system not to standards. If there is the slightest doubt the best course is to replace it, then you know. The cost of finding out the hard way far exceeds the cost of replacement. It wouldn't hurt to get a second hands on opinion either.

There are two designs of tensioner, the longer of the two is the updated and only one available.
You can tell a weak tensioner from a new one, many of the tensioners that come out when we do a timing cassette are weak enough to be compressed easily with a couple fingers, whereas a new tensioner will require both hands to compress.
