Some also mentionned loose part on the engine or exaust but not sure about how much it can affect the knock readding....exaust heat shield, lose tmic etc... You can also make a compression test to check engine health prior to look for anything but the engine...

Chain is loose on cold start, but if i let it run for about 10 seconds, and turn it off there is no play whatsoever. So i don't think it's that. Also just changed the rear motor mount about a month ago thinking that was the issue. Torqued everything down to the T from the directions damond sent me, and the KR was still there. Could the PMM be causing this?
Did a few pulls today to try and log and it didn't knock. It's really weird. Weather does not seem to affect it, and its just random. So it very well could be something loose in the bay. Have yet to do a compression test though. So that may be something to do this weekend if I can find some time.
