So far fixed the oil leak on my Silverado 08 with 155k. Installed the recommended deflector and a new o-ring. Oil pressure is normal. The engine sounds and runs quietly. The only problem was that the old gasket was riveted and trying to hold the new one in place when reinstalling the pan. I've cleaned the oil pan of mud over the years. I hope I get another 155,000 miles. UPDATE 8/21/2020 Should have done an update a few months ago. Replaced all recommended items, this seal failed after about 1 1/2 years. This is not a daily driver, very disappointed.
