when your time spent on marlincrawler.com is almost at a month
Try around 4 1/2 months
When your rear end locks up on a dirt road when you break a ring and pinion, you back up and keep going, tighten the pinion nut when you get home and keep driving it, then a few months later it does the same - rinse, lather, repeat, then when it lets go 40 miles from home for the last time sending a piece through the housing draining the oil, you're still able to drive it home.
When you're able to drive your truck with oil mixing into the coolant for 1 1/2 years before you decide to fix it, change the head and get another few years out of it before a rod bearing lets loose... at about 370,000 miles.
