Hope not...I would have thought you would have seen it though.

Dumb idea....did you insure that the torque converter is seated fully? This can damage flexplates. ......

I would HOPE I would have seen it, but.....

I did make doubly sure it was seated fully. BUT now that we are tlaking about this it brings to mind that I thought I had noticed (what seemed to me) excessive end play on the crank.

IF there is excessive play, would tightening the converter to the flexplate pull the converter from the fully seaated pistion enough to affect anything?

Just thinking out loud, here....

2X,

I little crank-shaft endplay is normal, but the tolerances are measured in thousandths of an inch. IIRC, normal endplay is around .002". That amount is barely perceptible by hand, it's usually checked with a dial-indicator.

I think it's unlikely 2 different engines would have the same excessive endplay. I wouldn't chase that idea.

Have you ever posted a sound clip of the pinging? I went back to your old thread to see, but didn't make it through all 57 pages.

A sound clip might help.

Funny you mentioned that. I was just thinking I should post one up.

I don't remember if I did previously or not.
I looked as well, and didn't find anything.

I'll do that after I check these few things out tonight and test drive it tonight.

Not sure if it will be of any help, between the sound I am chasing, the exhaust, etc.....

I used a piece of wooden broom handle to find noise.

That'd get me killed or arrested, at the VERY least... lol

It only does it under load.

Have you retarded the timing? Are you running non-original plugs?

PROBLEM SOLVED ..... I think.

After all of the discussion above and some extensive digging on the internet, I went to the garage with a full checklist of things to check.

I pulled the inspection plate, and dust cover.
Saw no evidence of contact anywhere. I noticed the transmission side of the ring gear teeth had a bevel on them, but it seemed too uniform not to be from the factory.

The inspection did cover had a dent in it about the size of an egg, approximately 1/8 inch; deep. But no signs of contact on the cover OR the torque converter.

Just to be sure, I worked out the dent on a block of wood.

image-2880027285.jpg

From there, I decided to check the torque converter bolts.
They all registered as torqued to spec according to my torque wrench, which at this point I have LITTLE faith in.
But I cranked them down a little more.

Took the Jeep out for a ride ... took off in first, quiet as always, shift into second .... Nothing. Completely quiet.
Turn around and same thing .... First was fine. Second ... quiet. Shift to third, nothing.
Ping/ knock/ clatter/ whatever ... GONE!

Unfortunately, it was getting dark and I hadn't reconnected the lighting harness (in case I'd have to pull this engine again).
So I couldn't take it back out after reinstalling the covers, to see the result there.

But for now, it's gone.
