Cold weather 7.3 knock
We've logged about 4K miles and are averaging 16mpg. Not too shabby. I have noticed a direct relationship between the black soot on the rear sheet metal and the mileage.......It's fun to tromp the pedal at 2krpm.
Ok
I've noticed that even after the vehicle has sat overnight, that the engine knocks quite loudly (aka cackle). It would seem to me that if there is air in the fuel that it's getting there via an air leak. Cavitation is a vapor issue, not an air issue.
So, where do I start to look for an air leak?
