Review on Dodge Cummins Valve Cover Gasket Set - 6pcs, 3902666, 12V 5.9L, 6BT 5.9 - Buy Now! by Andrew Amzallag

There was a lot of oil and dirt everywhere, it seemed like every gasket on the engine was bad. They worked great and fixed 100% of the leaks. The original gaskets fell apart when removed, the covers were cleaned, reinstalled, and the stream washed away the sediment. now day and night! And here's a photo of the truck because I know you'll appreciate it.
