broken piston ring
 

Customer came in with a 95 6.5 dually said it was smokin g some on startup..took a touch more cranking to start cold then normal. Original plan was timing chain tdco relearn and injectors and pmd relocation. Then I discovered it had tons of blow by so customer gave me go ahead for a rebuild. I yanked the motor tore it down and found a cracked head on drivers side that had coolant seeping out and top compression ring on #8 piston was broke and oil ring spring came out and went in oil pan!!! Thought I'd share this with you all :c:

Truck had 160,000 miles

Bummer I would guess you will be looking for another block then.

Nope block is in good shape just rings need replaced and camshaft

What happened to the cam?

Had friction pits on front cam lobes
