Okay, can someone post a photo of the two new types of rear main seals that are in these trucks? From what I've been reading in past posts, the originals were rope but the new ones are either flange or a two-piece split rubber type. I haven't started the engine disassembly yet and don't want to I have parts on the way. I found overhaul kits and it looks like I'll be needing to get the rear main seal separate.

Thanks!

Here you go http://bestgasket.com/pop_up_picture.as ... umber=3675 or http://bestgasket.com/pop_up_picture.as ... umber=4164 Rear main seal.

The timing chain cover seal is a National Seal # 6636-S, please note that you will need to remove the front slinger if using this new style seal.

Bert, Thanks that's what I needed. I found a source for the front seal now I'll need to search for the rear seal.

Tim,

Go to the Best Gasket site, it's a stock item. Search for a local stocking dealer.
