In Canada, I'd go with the 5W20 oil. If either works, thinner is better for cold winters. Since it's likely never been done, I'd do an engine flush before your oil change, use dino oil for this round with 1 qt. of Marvel Mystery Oil and next oil change, do a 5 minute flush without rev'ing at all. This will get your crankcase and lifters nice and clean. MMO is awesome stuff!

 

Try using a short piece of tubing to use as a "stethoscope" and localize the sound. Do the V6's have solid or hydraulic lifters? If hydraulic, there a some additives that are advertised to help relieve lifter noise.

good luck

 

if its a fast clicking that sounds kind of like someone typing really fast on a loud keyboard the valves need to be adjusted.
