I just purchased a boat with a 4bt 155. I was cleaning things up and found and unused opening on the engine. The two attached pics show it (same angle, just two different zoom levels).
What is it? What should I do about it? I'm sure it was not intended to be left open.
Also attached is a picture of the dip stick. There are no markings that I am familiar.. how to read oil level?
Is there a good online source of Fleetgard parts? The Cummins dealers nearby are all Mon-Fri operations, which rules out a visit to them.
Thanks guys. I've been a lurker here for a long time. Thought I'd give posting a try.
