I have 2 trucks with 6.5 engines, both over 250,000 miles, not buying that they can't run reliably if the balancers problems are addressed. JMO.

Brad, the cracking in 6.2/6.5 cranks was primarily in early 6.2 nodular cranks. We magnafluxed hundreds a month; never found a late 6.2 (one piece rear seal) or a 6.5 crank that was cracked. Since WHEN do millennial automotive writers know ANYTHING about anything?
