Driver said she started knocking and blowing out the blow by.   Went and drug it home,   got the heads and own off still haven't found the obvious problem.   Had to go get a socket to remove the rod caps so surely will figure the damage tomorrow.   

No chunks in the own but plenty of different types of shavings. 

Open to any tips as first time this deep in a dog . Thx

1.3 on chasis. 

No history.   I've put about 20000 on it.   Friend bought it at an auction in Arkansas, decided he didn't want it I bought from him.   

The heads looked new when he brought it home.   Had a oil leak on the right side cylinder #3.  Head gasket.

Yeah just hard to justify dropping 25k in a truck I paid 9k for. 

If the crank is bad idk what I'll do tbh.   I like the truck other than the 10 speed,  just re did all the floor in the cab.  

Would a 60 series fit in there?   

Not many good pull out Mack motors in my area.

What causes a rod bearing to spin? Besides heat? Just curious. 

Excessive idling can result in an oil film that can't support the load needed. Engine lugging can distort the crankcase and/or crankshaft, causing rapid wear the connecting rod and / or the main bearings to name to most common causes
