Carnage, What causes this?

[mtocrs1]

Not really carnage but not good.
What can cause the thrust bearing to get chewed like this?
All the mains don't look good.

Notice anything wrong with the head gaskets?

Stage 2 head gaskets? WTF? Who built that?

 

[mtocrs1]

Im not sure what gaskets they are but they appear to be blocking the coolant passages.
Some place in Canada built it in the early nineties ( I bet their out of business......). Car has been sitting for over a decade because of an engine noise.....
I have to imagine the car always ran hot. Any ideas what would thrash the mains like this other than lack of oil flow?

Incorrect line bore, incorrect bearing clearance, cap installed backward, crank journal issue, blocked oil feed, bearing out of spec

Is this what a torque converter ballooning thrust bearing failure looks like? Or do the TC ballooning failures only have wear on the thrust side?

After seeing that the whole build is in question !!

Is that a crack near the main stud?

Good Eye. Not sure, I will have a look.

That's the cap with a bolt in it, not the block register.

 

[mtocrs1]

No cracks anywhere. Probably will never know what happened.

I would bet that crank is cracked. Not visible to the naked eye. Have to be magnafluxed to really see it.

Good thought Rick. I think this one will get a new rotating assembly.

That's the worst bearing I've seen. Wow! X2 on cracked crank.

The only thing I've seen similar is when I disassembled an engine that had been started and run without priming the oiling system first. Can you post pics of the rest of the bearings?

#1

#3

#4

You have all already seen #2.
It seems that #3 got hot at some point. The cap even had some blueing on it.

I think it started off as lack of lubrication on initial start up and went down hill form there. It all looks bad and costly, I feel for you.

Thanks but no biggie. I bought the car right and knew it would need an engine.

I am struggling on what to do, I have a stock rebuilt long block ready to drop in. At first I was just going to swap over the ported heads and intake with the addition of 1.65 roller rockers.

Then I got all worried about the unknown spring pressures on the factory flat tappet cam.

So I have since decided to throw in a roller cam and have the heads reworked for the roller.

Now I'm thinking man that's allot of money for the roller cam with minimal gain.

What would you do? Roller cam for $900 and additional down time waiting on head work, or just throw the the unknown ported heads on with the 1.65 and be done?

Goal is a 10.99 street car.

Anyone? I'm supposed to drop the heads off today.....

What do you need to get reworked besides different springs? When I put a Comp roller in my last GN, I simply swapped the stock springs for some beehives with the heads still on the engine.
