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

Definitely the only way out, this is also an upgraded part with larger diameter oil pan bolts for more even torque around the oil pan, the crank seal is already aligned and installed in the oil pan, too comes with an oil pan gasket, this is difficult (remove driveshaft, remove gearbox and linkage, remove exhaust, gearbox lines and front driveshaft for 4x4). Do not work on your back when the vehicle is raised. The parts are best suited for this PITA job thanks to our friends at GM and the LS (Small Block Chevrolet Rebuild) engine. On with just airing! You need a lift and a gear stand and a good friend to help you! This is day-to-day business. So in my opinion, DO NOT buy cheap or inferior parts, get the best first time, just a few bucks more in the whole scheme of things, you only want to do it once. It's not difficult, you just need to have the right things in advance. Since then no problems. bone dry
