Glad my account of sealing the old Conway boiler may have sparked an idea or two... Now that I've sealed it up put this engine back together, I've developed this unwarranted fear that the cylinders aren't getting oil from the mechanical lubricator. Other than disconnecting the cylinder end of the lubricator line or waiting to see if the oil level in the lubricator goes down, are there any means of checking to see that the cylinders are getting the oil they need?
