Frozen piston rings
Hey guys,
Wondering if anyone ever saw this before...2006 6.0 in a 3500 express van. 60,000 miles.
Van came in with the right side having no compression, left side was fine. pulled right side pistons and the rings were stuck in the grooves so badly that when I did a leakdown test it sounded like a hole in the piston...Left side pistons and rings are fine...
Heres some pics
Any thought would be great!!!!!!

I see this occasionally on motors that run conventional motor oil. It is always customers who do not take care of their engine. Long service intervals, low oil levels, lack of maintenance.
