At this point is sounds like the motor needs to come out.
A seizure like this is not going to be easy to deal with in the truck.
Since he had it 2 days, don't be very willing to take resposibility for a failure he may have caused after saying he may have forgot to put the oil in on a change.. He know he did or did not.
If this is the case he put it in after the seizure. There would be no clean oil up in the engine after seizure. Look under the valve cover on the other bank if you did not have it off. No clean oil means he put it in after the fact.
If you find more than one rod and main bearing burnt fast it was a no oil situation.
Oil pumps on these motors don't just stop working from the design and way they they are driven off the front part of the crank.
There are a lot of bone headed people out there that don't have brains God gave a Goose.
See what happened, then ask 'him' what he wants to do about it.
It's at this point the real deal will be known.
Otherwise your out of $3000+/- trying to be a helpful friend.
I understand it's hurtful for you but these things happen to the best of shops.
On a job like this you should change the oil and filter as part of the job just from a contamination point of view.
Good luck.

 

Sorry i might not have worded that right......


His comment to me when he was on the side of the highway after i had him check the oil on the dipstick....he thinks that I forgot to put oil in it.
I did an oil change for him when i did the head just because i could see how nasty his oil was looking down at the bottom of his timing cover....looked like mud.

I definatly put oil back in the engine and checked the levels before starting it up. Then i delivered the truck to him 45 min drive on the highway. So i know for sure it had good oil in it when it left me....and it still has oil in it. So all that can possibly be wrong is a clog in the pickup at this point unless a chain broke and a valve hit a piston. but then i would think i should be able to rotate it backwards a little. Its quite the puzzle. I might offer to buy it off of him for what he paid me in parts and labor....then put a used engine in it.

How hard is it going to be to pull the engine out since i can't spin the crank around to get to the flex plate bolts? Can i pull it out torque converter and all?

 

Sorry, my reply was based on what you said.
Yes you are in a greater bucket from a seizure due to not being able to rotate the motor.
The converter will have to come with the motor as there is no other way.
Just recently some one from Europe tried to put a motor back in with the converter on.
After doing all the work he forced the motor back against the trans so you can guess what the outcome was.
The converter never engaged correctly with the front pump.
Good luck. Hope it turns out for you.

 

Yep Bluegrass said it right. just remember when you put it back together, put the converter back in the transmission BEFORE you put the engine back in.................Sorry to say, but sounds like your friend is at fault if "He punched it when the oil pressure was going down" he should have shut it off right away. (the owners manual tells you that too)

 

said it right. I cant tell you how many times Ive been lied to on stuff like this. This is also one big reason I dont help "friends".............got burned too many times.
