Motor was running then it stopped.

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.

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.

so much for that statement... I hate being right sometimes.

I would bi*** like crazy. They should refund at least. Then go from there. They did put the entire motor together right? So no possibility of human error on your part?

 

[Maverick4g63]

Keep us updated.

 

[Keithson30]

any word?

Just got off the phone with them. They said they have to check it for mechanical failure, so im towing the car to michigan, and they gonna put a new motor in for me.

It looks like mechanocal failure to me and 3 other mechanics I know that came over and personally looked at it .?!

 

[Maverick4g63]

Did you install the head and set up the timing?

Uhhh... that seems a bit obvious.

Did you get a chance to check this:

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?

Hope you get it back on the road soon!

 

[tenn-gsx]

Michigan? There are 2 shops that way that come to mind.

One in particular comes to mind for me, but we need to be sure and keep any discussion of that type out of this thread.

 

[tenn-gsx]

That is why I didnt say any names. Besides. If it gets fixed to satisfaction then no harm besides lost time.

No I have not its a bit obvious it is mechanical failure so Im gonna tow it up there and they gonna fix it.

Yes im keeping all that info on the vendor thread.

And yes if they fix the problem all I have lost is time, but time is money.

Glad they are going to fix it, but I would still check out the cams and oil pump just for your own information.

 

[Keithson30]

Ya I probably should. But anyways the question is now, is it mechanical failure on there part with everyone elses eyes ?

 

[tenn-gsx]

If you purchased a long block with timing assy and you put oil in the engine before you started then I see no way this could be your fault.

 

[Calan]

That's why you should check it out as much as possible. There's no way to know otherwise, and if they get hold of it without you knowing anything about it, they can say anything they want. (Not that they would, but why take the chance?)

If I were you, I would want to know as much as possible about any potential causes for the failure before turning it over to a shop that has to eat a lot of $$$ and defend their reputation.

Yes, and I have had 3 other mechanics come and inspect it. They all called it mechanical failure, had them come look at it as soon as I got it apart just in case they try and say I did it. I also have tons of pics and videos of my whole build. I work perfectly alone and I am very meticulous, I have OCD. I can't even stand my tools not being arranged by size from left to right.

So what all would you recommend I check before I tow this car to michigan on Sunday ?

 

[LambdaJoker]

Wait, your previous statement has now perplexed me. Who built it, you or some shop? If you took it apart, wouldnt that constitute as a teardown? But you said you have pics and videos of your whole build.

A shop built the motor. I rebuilt the rest of the car, whole suspension, brakes, etc...I paid for the motor to get built and it is supposed to be rated to handle 500 hp. I had to put all the bolt on parts on the engine and drop it in the car. I have spent about $8000 on this car for all the parts including the engine. I have been building this car for last 2 months and have worked on it for a couple hundred hours.

Feel free to view my facebook profile all the pictures of this build are on there.

Keithson installed the head and timed the motor. He is leaving that part out.

 

[GoofyDSM]

Whats the news on this thread, I keep checking it, wanted to see if they fixed your motor?

 

[tenn-gsx]

Keithson installed the head and timed the motor. He is leaving that part out.

If that is the case then without pics of the timing marks it is pretty much impossible to know if it is the fault of the shop who built the head or the owner who according to you installed the head. Op post pics of the tops of each piston intependantly. Also close ups of each combustion chamber on the head.

 

[Maverick4g63]

Exactly. Now that he has pulled head the evidence of jumped timing or improper install is erased.

I'm sorry, but all your suspension work and money you have invested into your dsm has nothing to do with your valves dropping into the combustion chamber. Everything in this post is irrelevant to your problem at hand. What's important is did the shop install the tbelt or did you? Once that is determined, then the kind folks on this forum will instruct you on what to do next about your situation.

 

[Gasolinebaptism]

Good luck is all I can say.. If it was mis timed then it's your fault and there should be damage on each cylinder.

 

[tenn-gsx]

Basically If you installed the head,Cams, or timing assy and ther is damage to any other valves or cylinders then your SOL as it will be considered incorrect timing.

If the shop installed all of these components then it will be their fault as long as there was oil in the engine.

If there is no damage to any cylinders or valves other than the one with pictured broken valves then it doesnt matter who put the head and timing assy on the short block. It is pretty much the fault of whoever built the head.

 

[Keithson30]

Sorry people been busy all day doing a full service on my truck for this road trip. I will post a video tomorrow of everything. Only the #4 piston and valves were damaged all the rest of them look good.

See cam gear pictures, and an email I got from them today and the email I sent back. (I removed there names. So we can try to get this solved in a peaceful manner)

Why does he not want me to bring the car up ?

 

[tenn-gsx]

Because. Even the BEST most RESPECTED shop isnt going to swap the engine for you in this type of situation. They will rebuild/replace the engine with a new one and send it to you.
