What is airlock in diesel engine?

Air locks are caused by air leaking into the fuel delivery line or entering from the tank. Air locks are eliminated by turning the engine over for a time using the starter motor, or by bleeding the fuel system. Modern diesel injection systems have self-bleeding electric pumps which eliminate the air lock problem.

Where does the oil collect in a Freightliner RV?

They collect water condensed from the air, and small amounts of oil normally enter the reservoir in the form of vapor, because of the heat generated during the compression. After the water and oil condense, they collect near the tank drain valves and should be drained regularly.

This is every twelve months or 15,000 miles, whichever comes first.
