Well I dropped the oil pan tonight and it's not pretty. The cylinder liner is rusted heavily on a couple cylinders and in one spot the cam shaft is heavily rusted. I think it probably has a blown head gasket, and was left sitting with water in the oil for a long time. I am not a diesel mechanic by any means. It looks to me like I definitely will have to pull the engine. Hopefully I can find a new cam shaft and lifters. I may take the engine out and then take it to someone who knows what they are doing and let them rebuild it.

I didn't do it tonight but tomorrow I will spray down the inside with WD40 or something so that it won't rust more while is is sitting there open.
