Not much chance of getting me do do anything. I have piles upon piles of unfinished things that need to be done. Anymore my life is about running the business and putting out fires. Successful one employee businesses can suck in that regard (sorry). A sign the timing set is worn is a slapping sound emanating from the front of the engine (typically loudest when cold). Still, I've seen these go for a long long time with this condition, so if you haven't noticed it yet then it's probably okay. When the tensioner is extended all the way and the chain is still loose the slapping sound occurs. Excessive slack is usually a combination of a stretched chain, worn gears, and a worn tensioner. The tensioner has a contact pad on the end and that's what usually gets the brunt of the wear. If it gets really bad, contact with the timing cover can occur. Here's a picture of one that was really bad. Note the grooves on the right side of the aluminum timing cover:
