2001 LS1 forged rod/piston, studded 241 heads, 11lbs D1 procharger, approximately 5k miles since rebuild. Looking for any likely scenarios that could possibly cause this. I was trying to sell the car a while back when I was overseas and let a buddy clean it up and take to some potential buyers. Came home to a car that wouldn't run more than 6-7 minutes and lots of coolant steam coming from the oil fill tube and catch can tubes. Of course I got the "it was fine when I parked it" speech. Hard to tell in the pics but each main journal is cracked and all the main and rod bearings had either spun or were gaulded. In the last pic, yes that crack goes all the way to the cam bearing.
wow Iam no mechanic but from the like's of that it seems to me pretty common sense....looks like whoever had it...did indeed have fun and let it get away from them. My guess about 10-12,000 rpm? Possibly someone missed a gear while racing someone else? Whoever it was that "parked it" I wouldn't trust them with a potato gun.
From: Dear Karma, I have a list of people you missed.

My first impression is oil starvation, for what ever reason, i.e. ran with extremely low oil level (or out of oil), oil pump/pickup tube failure, etc.
You can see where the crank has moved forward and/or aft enough to scuff the main caps and block. Possible outright thrust bearing failure due to oil starvation issues.
I think there was lots of heat present to crack the block like that.

Its an auto car. Rev limiter was set at 6500 I believe. Oil pump was the norm..ported oem.
For a crank to walk for and aft that much on a pretty new motor.... Seems to me that if the crank is walking you're going to get oil starvation on the bearings which would pretty much do what you see. Or oil starvation would cause crank walk. Hard to know which came first, right?
but there is no way in hell that the person that parked the car in that shape didn't see or hear it. That is, if it was even running when it was parked last time and wasn't towed in.

I agree. Like I said it would not run more than a few minutes without going dead on its on. I have no idea how he got it home. Theres no way I could even get it out of the driveway until it left on a roll back.
Iv always wanted a LS block table for the man cave but I sure didnt want one this way. I think I may just end up pissed off everytime I look at it.
Cool idea for a table, indeed!
Not the way I'd want to go about getting one though.
If someone did that to my car they'd get a one-way trip to the Louisiana bayou. Gators just love ham. You could tie a ham to just about anything and gators would go crazy and fight each other over it.
At the very least somebody deserves an ***-whoopin' with an economy-sized can of whoop-***.

No car is worth losing a good friend. If you trusted him enough to leave your car in his care, then why the hate ? Also the last thing I do coming home is "give it hell" just before I park it. Any chance your friend is telling the truth??

The so-called friend lied to him about it. That would do it for me if the cracked block wasn't enough. A real friend would be up front and admit he was at fault, then offer to pay for the repairs.
