YouTube - my motor running

YouTube - my motor not starting

Ok here is a video of when i first started it. And a video of whats happening now.
Its was running fine then I heard a noise and the motor stopped. Now it wont crank, it looks like it is trying though. I already pulled the valve cover and dont see any bent or missing valves. I also rechecked my Torque on my head and it was all still good.
 
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.

The whine really sounds like an oil pump. But before jumping to "it needs a rebuild" pull the plugs on it and try turning it over. If that does not work drain your oil and see if any metallic flakes come out. If you dont see any pull your timing belt off and see if either your crank or either cam is seized. Just remember to be carefull turning the crank as your valves will be out of time. Good luck and keep us posted!
 
So pull the plugs and try to crank it ? If it dont crank drain oil and pull oil pan and look for stubby shaft ? Then pull timing belt if no stubby shaft present ? Also if the stubby shaft is in the oil pan or there are lots of metal flakes is that the builders fault ?
 
Yes. What I would do is rotate it backwards a full turn, if it makes it around then rotate if forward. If it can turn forward again then whatever was stuck has fallen out, which would more than likely be the oil pump shaft. Turning the motor backwards isn't terribly bad for the motor, but I wouldn't do it for very long or often.

It's easier to use a ratchet on the crank to turn the motor. The bolt on the harmonic balancer and with the spark plugs out. Which you should have the plugs out and inspect inside the cylinders anyway. if you can rotate it backwards to a certain point and it stops then goes forward to a certain point and stops then there is probably something in the cylinder.

I'm betting something in the cylinder, like a broken valve or bolt. Since we're starting to take bets with this thing...

Do you realize how much force it would take to stop an engine dead? A valve would not be causing this, it would have punched its way through the piston already and it wouldnt have been a sudden stop. It would have been a loud commotion of knocking and banging. It wasnt getting oil is my theory. Maybe the balance shaft bearings were not put in properly. The bottom end could still get some oil but not enough to travel to the top end seizing the cams. Thats why I recommend doing things in the order I listed.
 
Did you put in the balance shaft eliminator oil blocks? cause i know if you forget to put the blocks in where the BS use to sit, you will have a internal oil leak, and lose pressure. unless im wrong. please correct me.
 
Here's a question for you, where did you buy your balance shaft elimination kit? Ebay, or was it an oem kit?

The reason I ask is because my friend bought an ebay balance shaft kit, and the stub shaft did not have an oil grove in it. It caused his new motor to seize after running for like 10 minutes.
 
sorry, forgot you had a 6 bolt. 7 bolts you cant get the main girdle out with the front cover on. But thanks for trying to pick me apart after I help you.


Ummm, he isn't the OP, just has a similar avatar. :confused::thumb:
 
Did you eliminate the balance shafts?? Maybe the oil pump gear got messed up. Happened to me and the same thing happened.

The people who built this motor bought and installed it.

Not sure what you are referring to by "BS oil blocks". Most people just rotate the BS bearing to block off the shaft oiling holes.

How much would a shop charge to fix this ? Im tired of working on this car, and need it done faster than I can do it alone.

Step back from it for a bit and take a deep breath. You can at least figure out the problem before spending a boat load to have a shop diagnose it for you, on top of fixing it. :)

A lot of good suggestions have been posted here. Do the easy stuff first:

1. Check the oil for metal flakes.

2. Check to verify that nothing fell and got lodged in between the flywheel and starter.

3. Pull the plugs and try to rotate the motor, first CW, then CCW (Be careful when going CCW; make sure you don't loosen the crank bolt). If it will turn, verify that the timing has not jumped (marks still line up), and inspect the t-belt for damage.

4. Inspect the top of the head carefully for heat scorching around the cam journals, and verify that there was plenty of oil getting to the top of the motor (at least for a while LOL. Double-check the cam cap ID's to make sure they are in the right place.

5. Do a leak-down test to find out if you have some major internal damage such as a hole in a piston, broken rings, cracked cylinder, etc.

6. Pull the oil pan and verify the gasket on the oil pickup tube was installed. Then check the stubby shaft and make sure it's still tight. Visually inspect the cylinders, rods, and pistons for any signs of wear or damage.

7. If you still haven't found anything, pull a main cap and look for signs of oil starvation. Do the same with a rod cap.

8. If everything still looks good at this point (which I doubt), pull the cam gears and see if the cams will rotate freely. If so, pull the t-belt completely and try to spin the crank again, and check the oil pump.

Knowledge is power... the more you know about what happened to your motor when dealing with the shop that built it or a different one, the better off you are.
 
sorry, forgot you had a 6 bolt. 7 bolts you cant get the main girdle out with the front cover on. But thanks for trying to pick me apart after I help you.

I wasnt picking you apart. Also why do you say you cant drop the girdle in a 7bolt with the front case on? I did it on mine. Did I possibly screw something up? Im not the OP either.

Last I remember the girdle wouldnt com out with the front cover on with it bolted to the trans. Tho I may be wrong. But still wouldnt pull all of the caps off, just one.
 
At least take the plugs out and inspect cylinders and try turning it. That's not going to take very long. Just eliminate easy stuff and move on to harder things.

I don't think it's the cams/valvetrain locked up because in the vid the cam gears try to move. I think it's crank or piston getting stopped or even broke.
 
Im so pissed off I cant find motivation to go take this stuff apart, supposed to be leaving to Florida with this car tomorrow !

Well I went and pulled the plugs out and looked down the holes and saw metal, so i took off the head and here is the problem. (SEE PICTURES)

So how did it run for 30 mins to an hour and drive down the road, and then this happen the next time I start it ???

Ouch!

My bet is an oiling problem or an issue with excessive belt tension, cam caps, etc.. If you had of jumped timing in the "normal" sense with the car idling or under a low load, I doubt you would have valves that are snapped like that.

Something seized the valves and prevented them from moving while the crank continued to rotate.

If you haven't done so already, pull the cam caps and see if there is heat scoring on them or on the cam journals. For that matter, do the cams spin freely now that the head is off? How about the oil pump?
 
Wow... On a brand new motor... Gl man I would be on the phone with whoever you got this from...
