In slo-mo it sounds like the different crank counterweights hitting windage tray- it’s a random pattern and sounds like steel hitting sheet metal.

I would send it back. You’ve already spent your shipping fees in chasing your tail. If you hear the noise consistently then Paul will be able to duplicate it. You are beginning to get too many fingers in the pie. It’s just like the last cam swap I did for a guy he brought it back to me with it obviously running on about 6 cylinders. When I took the valve cover off he had his friends over chasing a ticking noise and one that didn’t know what he was doing tightened the **** out of all the rocker arms wiping the cam out. Lost a friend over it cause I told him I wasn’t buying a new cam and lifter set when work was done after the fact. Paul is being very generous on letting you send it back and I would take him up on it. Your mileage may vary

grivera,
Damn...I never thought about that. Even after correcting the spacing, you think it could still hit?

64speed,
I spoke to Paul today and he wants me to pull the coverter back and see if it still makes the knocking noise. After reading what grivera just wrote, that really does make sense. I know I've had a few hands on this motor but Paul has been there every step of the way. Throughout this whole process, Paul came up with different things to check and or replace. He has spoken to each of my friends prior to them or during the testing process. He really does stand by his work. I'm going to do this last test of the converter and if that doesn't work, that motor will be headed for a long ride to Arizona.

Yep ... that sounds random ... not a crank/rod/piston/wrist pin ... it sounds random. Certainly does sound like something hitting the oil pan to me. Doesn't not sound like the solid impact of important parts against important parts.

I still say .... Go Fund Me to send it back if necessary. Jeez, we are all in this together, YOU, Paul, all of us in my opinion .... I'd be happy to contribute. Paul has provided reams of very valuable information to this forum and it would be small pay back to contribute a few bucks to hear his opinion after getting his hands on this engine again.

[Va68goat]

dataway,

Yeah, I agree. It sounds like hard medal hitting softer metal. I don't think I will be the one to set up a GoFundMe, though I do appreciate the kindness. Paul, Jeff and I have an unofficial agreement regarding shipping the motor back to Arizona then back to Virginia when it's repaired.

I had a custom wooden crate that was build by a business that is right around the block from Pauls shop. Does anyone have a stand or crate that can be used for transport?

Vidguy (James) had one for loan in the past - not sure if still available:

Those spacers installed added like a 1/4", I seriously doubt anything is still hitting the tray. The witness marks were very minor to begin with.

Here’s what I think based on when I can see in here. It sounds Tinny.
Put your hand on the oil pan and feel for any type of Obvious strong knock.
Make sure the torque converter bolts are actually pulling Tight And not bottoming out .
Then run it with the converter backed off.
Next I’d have to go have a look at the flexplate mounting bolts to the Crankshaft.
I don’t know if it’s just a photo that you have of the flexplate but the torque converter mounting bolts area looks like the bolts were chattering, and it looks like the tour converter bolts have the threads beat on them where they ride in the flexplate.
It sure sounds like a flexplate problem to me
And there you go my two cents

You didn’t verify Before closing it up?

[HWYSTR455]

It didn't hit when the engine wasn't running with the original spacers, it was only once the engine was running that it hit, most likely vibrations, combined with close tolerances. There are 4 points of the tray mounting, adding a 1/4" was overkill, and there is really no way to check it under those conditions unless you started it.

What kind of gaskets are you using between the RA exhaust manifolds and heads?

[chiphead]

Good questions. If it's not the windage tray or the oil pan, it COULD be an exhaust tick. That would be something that the builder would not have seen. I built a new motor for my Silvy, and during the first test drive the pass side manifold bolts were a tad loose. I stopped at a red light and I'm hearing this tic tic sput sput tic tic noise. Tightened the manifolds and it went away.

I'd check the manifolds for cracks, check the head mating surfaces and reseal with new gaskets.

[Va68goat]

Holeshot71,

I think we used the Fel-Pro metal gaskets. I'll take a look and confirm when I look at the pile of receipts.

[dataway]

I say we start a Raffle ... $5 buys a guess, half the pot to the owner, half to the guy that guesses the closest to the actual source of the noise.

This is why I asked. I tried to use the "tin" fel pro gaskets with the round compressible surface between aftermarket RA manifolds and 6X heads. I found that the round surface didn't compress in some areas due to surface mismatch. The manifolds did say to use the fel pro performance header gaskets which I did use and had no issues.

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

The brand new manifolds out of the box were warped BAD! When I set them on the granite slab, there was probably a .040" bow in them. This has been the case with most of these manifolds I have installed new. So we took them and surfaced the gasket surface until they were flat. The steel gasket should work fine with them. Out of the box I could see you having to use the Fel-pro blue header gaskets or some Remflex. After surfacing them, they were flat so there should have been no need for special thick gaskets.

I seriously doubt that unless it's external.

[Formulajones]

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.
