Now when I first started on my truck I "thought" I had a rear seal leak. I had my transmission and flex plate out of the vehicle already, so it was a no brainer to replace this seal. I will start with the rear main seal because it was more straight forward.

Keep em clean.įYI: My post is not a 100% how to, but a little reference and maybe some help to someone with similar issues. I hate dirty engines and grease covered parts. Neither were bad enough to drip on the ground when parked overnight, but there was enough to make things turn oily on the surrounding areas. Before I started the work I knew I had an oil leak out of my front main seal on the crankshaft seal and I thought same for the rear. Recently I did some extensive engine work to my 20 with the 5.9L Cummins engine.
