Ok, so I could not find the thread where I thought I posted oil pan info, but here is a new thread to add to the stickies instead of just replying to a pre-existing thread. Would one of the moderators please add this to the 4BT Technical Topics Index under "Oil Pans" in Post 9? If anyone else has oil pan info such as "Dry Sump" would you please get the moderators to add it to the Tech Topics Index as well?

First, here are the part numbers I know - they are not current, but were in the original parts books - and someone else can pitch in other numbers below:

Hopefully this helps answer some questions.

I figure that most of those part numbers have been obsoleted by now. Seems like every time Cummins raises a price on a part they also obsolete the old part number.
