I do not have video of it or a sound clip, but when the engine it running it sounds like the flex plate bolts are loose. I did check them and they were good and tight. however the sound is still there loud and clear? I was told today that it may be a collapsed lifter. sounds expensive.

I was just wondering if ayone else has heard what i am describing. it only knocks/ticks every revolution. it also does not go away under load or at 2k rpm.

Ideas?

 

The flexplates tend to crack around where it bolts to the crankshaft, you have to look really carefully with a flashlight to see any signs of cracks.

 

Na, no cracks. I had a shop light up in there and it was in "like new" shape.
Weirdly, I just drove it and the noise was gone till the engine got to about 150 degrees and it was clear as day (inside or outside).
