I know you mentioned you were going to, but did you end up checking the Crank sensor at the back of the block? Had many FWD's do that after putting them back in. They usually sound different than that but It would suck to pull it all apart for something on the outside. I wouldn't trust just looking at the flexplate for evidence, see if you can move it slightly away from the flexplate. The noise sounds way to constant to be a vlave guide or pushrod at that rpm.
Just ideas.




I did check it and there was no signs of rubbing anywhere on it.

However,

I THINK I FOUND IT!!

#5 exhaust lifter...


tell me what you think...

This thing had me about to go crazy today...I started it up and it ran for a good solid 10 minutes, with no squeak at all. I thought "that's weird...did it just go away?"

I was about to take it out and drive it around because after everything was good and hot, and several starts of the engine, I couldn't hear anything.

THEN it came back again.

ran the valves again on the passenger side, no change.

started to kill cylinders on the driver side and got to #5 and it went away.

a whole new set of lifters are on the way, and I'm not running this anymore before that #5 lifter drops the roller and bounces metal off the cam, crank, rods, etc.
