The valve cover gasket PN I have is 897349416. I think that actually translates to 8973494160. I think they just left off the trailing zero on my reciept that I read it off of. I didn't have a source for the number, so just ordered one for from a local marine shop. The guy I talked to has been very helpful and checked both the 4JB1 and 4JG2 numbers he could find in his catalog and came up with that which is, as he said, common to both. It was slightly different than the one I pulled out of mine, but worked just fine. The difference was that the original had 'moulded' curves where there was extra bends in the cover and the new one didn't have moulded portions there. That was no problem. Not sure if the moulded portions was fromt the factory originally, or if it just set from being on the motor for 15 years.

Thanks for the seal numbers. Sorry I don't have a suggestion of how to get the glow plug out. I'm new-ish to diesels, so haven't run into that one. Hope you can get it out without pulling the head. Ping Jerry?
