Thoughts? 600 miles on motor. Freshly rebuilt.
Also had 2 blown head gaskets. Never took the motor passed 10lbs of boost, let alone raced it.

fyi, took a prybar to get the cam out of the engine. Metal shavings everywhere. Main bearings are shot obviously. Cam is toast.
 
That sucks Eric, I was up there when they were pulling it apart.
I hope your engine builder makes it right.
 
Did you take the oil pump apart? Buick engines are infamous for wear there because of the aluminum housing (timing cover), which could cause oil pressure/priming problems.

Sorry about your luck.
 
Damn man, that sucks!

The same machine shop built one of my motors and I had similar problems. It only lasted 500 miles and needed full machine work and rebuild.
 
From the looks of the picture, the motor seen detonation. By the looks of the caps, they where moving around alot, causing load on the bearings. How did the rod bearings look?
 
Also, with the head gaskets being blown, you could of washed the bearings out with water when you blew them.

Did they work with you on it?

They offered to.

I included their name in a lawsuit. I already had it at another shop and they were already working on it.

I dropped the suit against them and collected from the other shop that was named.

From what I have heard about them they do good machine work but their assembly work sucks.

As long as they offer to help with the machine work and make it right than I don't have a problem. I can get it assembled somewhere else.

Surprisingly good.

What is good, do you have a picture of them? The caps where definently walking, you can tell by the flats on the caps. That will destroy a bearing for sure. I dont think it was the machine work. If the line hone was incorrect, you would of grab a bearing. Who tuned the car?

I do not have pictures of rod bearings, I am just going off of what Sean @ CARS said he could see. I can see if I can get some pictures of that when the motor comes back from the machinest.
Mike at Fullthrottlespeed.com tuned the car. Sean thinks that the hone might have been incorrect also and we will know more when the machinest gets back with us.

Let me know what he says about the hone. I had a hone problem and that caused all the other problems.

I didn't know Mike did tuning, I thought he just sold parts now.
