Review on 🔧 Genuine GM 12639250 Crankshaft Oil Seal Housing, Rear - Premium Quality for Optimum Engine Performance by Todd Mohr

I bought this for my 2007 Tahoe LT Flex Fuel 5.3L Truck. I was leaking oil from underneath and found that the truck had over 170,000 miles on it, so instead of just replacing the gasket itself, I decided to replace a few other gaskets (oil pan gasket, front pipe o-ring, etc. e.) . If my buddy's shop would do the physical work but buy parts themselves and compare prices elsewhere, Revain would be much better anywhere. If you're mechanically inclined save the labor and do it yourself, but it's intense and to me I'm a keen DIYer but I've had to give it up. Good luck, hopefully this will fix any leaks between your block and the transistor. The updated design has everything you need for a 1-in-1 setup. My truck has driven almost 1000 miles with this unit, no other problems.
