If oil was dripping in one cylinder, you'd be getting a skip in time with whatever cylinder was having the problem, or something similar. You've got a lope going on there, exactly what mine was doing with IP issues. A skip/miss is due to one cylinder having less power than the rest. A lope is due to the fuel rack oscillating and causing acceleration/deceleration of the engine. If the internal works of the IP are gummed up, you can expect that kind of behavior.

I get a skip and a lope... I think your right on the IP being gunned up. When I performed a diesel purge a lot of algae microbes showed up in the purge bottle aka gatorade bottle. I'll diesel purge once I'm for sure all the algae is gone. That will probably clear up the cold start issues. I also need glow plugs too. The light doesn't come on anymore. Only after it's started. So I'd assume one or two more glow plugs are bad.
How much would I expect to replace the guides if they are Bad? I'm not looking to spend a lot of cash, but I will do the job right. Even if that means just finding a lower mileage used head.
