I'd bet its crankshaft related, something is rubbing.

I seriously doubt that unless it's external.

I run all the manifolds over the belt sand table. Unreal how uneven those things are. Afterwards I've always used either steel or copper for a gasket and never a leak.

You guys have already cut the filter apart and never found anything, oil pressure is rock solid. Tells me the inside of that engine is just fine. I believe what ever it is, it's outside the engine.
Just listened to the video and it sounds like it's at the rear, but hard to tell because the camera never stays in one place for too long. Matter of fact once listening to that video, my youtube popped up a whole bunch of similar noises just like that, and everyone that I watched that had comments stated it was in the flexplate. One video in particular could have been laid over your video and you couldn't tell one apart from the other. It was a straight 6 cyl jeep Cherokee, and he found out it was a flexplate. Thought that was funny.

I hope it is too. I hear a "double tap" and I dont think there is anything else that can cause it. Especially after the converter bolts have been checked/verified. I would think if its flex plate related, you would see some sign of a crack, like a rusty spot or be able to push or pry on the plate in a way to make a noise.

Is the oil filter by-pass (in the filter adapter) still intact and functional?
IMO As it should be for a street car.

And why do people keep posting "no metal in oil"? Where is that info coming from?

Wish all the videos were back up and people would try to cypher through relevant posts and pictures by the OP and the hands on folks that have been helping him.

Also, while this car is in the air...please check crank end-play and turn the engine by hand to feel for that loud clunk clunk that happens when the engine gets cut off.

Ok, I'll ask as I'm sure many want to know here.... What happened this past weekend on this deal?

[Va68goat]

LeGoaT/As,

Thanks for your message. I just responded back!


aceaceca,

I've done a visual inspection of the flexplate while it's on the car and I don't see any evidence of cracks. I'm hoping that none of what you described has occurred..hahaha. This motor has less than 200 miles on it. It hasn't been right since the day I started it. I'm hoping to get things looked at this weekend. grivera, has a good point...there's no reason to pay to have the flexplate replaced if we pull the torque converter back and it's still knocking....you guys agree with that?

Not sure I agree, it might only knock with a load on it from the converter. Also, if there's something the flexplate is striking on revolution, with the flexplate off, could see witness marks.

That's my point - if it only knocks with the load on it from the converter he will know when converter is pulled back. At that point we can assume it's either the flexplate or the converter. If the sound continues after pulling the converter back I don't see how it could be the the flexplate because the sound is very random in nature.

ABSOLUTELY No blame on the “cooks” at all...just get it back to the Chief Chef!

Awesome that these great guys here helped you, something rare these days indeed!
A Testament to the Great company we keep here.

You’ve exhausted external possibilities it appears.

[Va68goat]

dataway,

What does that mean? "turning or firing at half crank speed." What causes that?

I just got home and I'm going to post the videos from when the motor was first started to the last few tests that were conducted.
