THE best way to find out is to simply open up the oil filler cap, use your finger and press/pull on the chain.
How much heartache and apprehension could this tip help avoid??!!

Checking if your timing chain is loose through the oil filler cap is the easiest way to find out if there is a problem with the tensioner. If the chain has tension on it, it doesn't rule it out as the problem. I also had my wife rev the engine while I was up front and heard the chain slapping against something. So I knew, there was a timing chain issue. With all that said, I'm glad that I was able to quickly troubleshoot the root cause of the issue. I would hate to tear things apart and replace without fixing the actual issue.
However, if you do hear or notice problems/issues with your LR vehicle, then you should just take it directly to the LR service dept or a LR mechanic.
I have done this, but I have nothing to compare against. Should a properly functioning chain system be drum tight, have some give when depressed, etc?
Did you use the "crankshaft locating tool" that bolts in place of the crankshaft position sensor "CKP". The service manual seems to imply that you can locate TDC by using this tool. Through inference, it seems like you should only be able to seat this tool and bolt it in place with the crank keyway located at 6:00, and thus #1 at TDC.
Funny that you mentioned it, because I actually had the tool in my toolset. I just didn't know what it was until after I removed the crank pulley. Again the workshop manual is vague at best. There's no "Timing chain guide". It's all how to remove and install parts, you have to have an understanding of what parts need to be removed, such as cooling, belts, and the actual parts. Oh by the way, if you're renting the pulley puller from Autozone its called, "harmonic balancer puller for GMs".
