It was running, you heard the noise, and it immediately stopped then and there? Or, wouldn't start again? What has recently changed on the car, can you give more detail?

Have you tried turning it over by hand?

Almost everything has been changed. Except the transfer and transmission. Its a new motor and head.

No i havent tried turning it by hand yet, that was next.

I just went out and tried to turn it by hand. It wont turn clockwise the way its supposed to go but it will turn counter clockwise. Im not sure how far it will turn counter clockwise I only went a little bit, and then turned it clockwise back to where it was, where it stopped turning.

Don't take this the wrong way, but did you put oil in it? It is a new motor so gotta ask...

put a ratchet on the crank and try to turn it either way a full round.

It acts like it's locked up, so I would look at places where something would interfere. Pull the spark plugs and take one of those magnets on a stick things and reach all around in the cylinder to check for a bolt that might have gotten into the engine. It's easier when the piston is BDC if you can turn it at all.

there is a place on the bottom of the tranny next to the motor to look up at the clutch plate, try looking up and around in there for anything odd.

I'd pull the starter and see if it has something wedged in the gear or something wierd.

last thing I can think of is pulling the oil pan and checking to see if a rod has come off the crank and got wedged.

That's all I can think of right now, but you kinda get the drift. You can see the cam gears turn, which is a dead give away that the starter is engaging and trying to turn, but something is preventing it from turning physically (I may be stating the obvious).

Yes i put oil into it, pumped it through the oil filter housing to prime it. I didnt think you were supposed to turn the motor backwards, I turned it backwards just a little bit to see if it would turn that way. Im guessing something with my timing belt or gears or tensioners are messed up.

Did you pull all of the plugs when you tried to turn it over by hand? Cylinder compression plus a new valve train can add a lot of resistance. Pull the plugs if you didn't before, and try to turn it by hand again.

Are you sure the timing belt was installed properly and at the correct tension? There is a really strange whine in the first video that sounds to me like an overly-tight t-belt.

Ill try to remove the sparks plugs and turn it tomorrow. And im sure it was installed correctly not so sure about the belt tension. So if the timing belt was overtightened what could that have broken ?

what kind of noise did you hear?

Like a clunk almost like something fell in there, but i know nothing fell in there i had it running for a while before I turned it off and started it again.

Im betting something seized, If the crank isnt turning when you try to start it then the clunk was something that happened to stop that rotating assembly. I would go ahead and start tearing down if it was me.

Did you eliminate the balance shafts?? Maybe the oil pump gear got messed up. Happened to me and the same thing happened.

Yes the balance shafts are removed, got removed when i got the motor built. And this is a fresh build so im not tearing into anything to far until i know exactly what caused this.

Oh i see..well if i were you i would check and make sure timing is still correct and check the oil pump pully and see if you can turn it fairly easy.

Pull your valve cover off and you'll probably find the problem.

I pulled the valve cover and rechecked all the torques. Then looked at everything closely it all looked fine.

Did you double check that all the cam caps are in the proper place and facing the right direction? No thrown rocker arms? Good thing I'm not a betting man cause I would bet you threw a rocker arm. Next thing I'd guess is jumped timing causing valve to piston contact when you rotate clockwise but not counterclockwise. Good luck with it.

Yes everything in the top of the head looked fine. It has to be something with the timing belt. Maybe to much tension but im not sure, thats why I posted it on here.

Now someone correct me if I am wrong, But did you hear a whine in the first video or was it just me? Because to me it sounded like an oil pump noise. The thing you heard fall could have been the stubby shaft. Heard of it happening before, when the shaft falls out the oil pump gears can move around free in the housing. What does your oil pressure look like? Im thinking your engine is seized. Who built the engine?

I would drop the oil pan, and take off the pieces that hold the crank in then try and turn it over by hand is it turns freely then you just spun a rod bearing, if it doesnt you probably melted a piston.

Going With Seized engine, did you have it align bored, im thinking dsmornothing is correct, thats what it sounds like.

Taking off the main caps so the crank can try dropping out and probably mess up the bearings? sounds like a dumb idea. He didnt melt a piston or spin a rod bearing.

Yes there was a whining in the first video. The oil pressure was fine while it was running, I turned it on and off a few times to check oil levels, coolant levels, and check for leaks. So seized is needs rebuilt again ? Yes it is bored .030 over.

Drop the oil pan and see if the stubby shaft is in there, Im almost willing to bet it is. How long did it run with the whine? and did the whine start after you heard the noise? Did you build this motor? Also were you looking at the factory oil pressure gauge? sorry for so many questions but im trying to diagnose this for you!

As soon as I started it for the first time it was whining, then I turned it off checked the cams for play, then restarted it. It was still whining so I drove it a few miles then pulled back into garage, turned it off checked everything again visually, restarted again everything still good, turned it off went inside for a 30 minutes or so came back out restarted it and then heard the noise and everything stopped by itself. And no it was professionally rebuilt. All the questions are fine with me if it helps me fix my problem. Thanks for the help.
