I thought it was the hidden cash for clunkers mechanism or how to get rid of first gen Durangos lol
Mine lasted a quarter million miles :P I have a buddy with three 4.7L trucks and he said his wife drives one 1000 miles a week, and he changes the oil with havoline every three weeks, and when the thermostat stuck and it overheated and cracked a piston, the crosshatches were still present on the cylinder walls after 250K

That's a lot of oil changes, esp if she is running highway miles. If he ran full synthetic, he could easily triple the oil change interval. I run QSUD 0W20 (around $18 a jug at Walmart) and Fram Ultra Synthetic XG 16 filters (a far cry from the orange can of death). The oil is run for 7.5K and I run the filter for two oil changes, so 15K.
This is my dipstick at 5K, with about 12.5K on the filter.

Yeah, but, it only works once, and can't reactivate the cylinder.
Realized that I had not posted what we found when we pulled the pan off, also full disclosure this damage was NOT caused by any members of my family...it was a CraigsList find with "only a blown head gasket" and about 93k miles on the odometer.

This is the final product we installed in the Durango: Daytona Yellow and Grabber Green engine paint
