How to diagnose Toyota Timing Chain Rattle or Knock troubleshoot 22R 22RE 22RET

Every Toyota 22R series engine with the single row timing chain and plastic timing guides (1983~ish - 1995) that I have ever purchased with over 100,000 miles on the engine has had a driver's side guide that was either partially broken or just totally gone. To the untrained ear it sounds a like the valves need adjusting, but in this video I'll show you how to inspect, troubleshoot, and diagnose a broken driver's side timing guide. It makes a great bargaining chip when you can show the seller that the timing guide is broken and then inform them that it's an $800+ repair at a shop. If you can fix it on your own it will only run you about $100 in parts and a Saturday's worth of time.
