3. Filling the Oil Sump
Add fresh oil through the oil filler cap on the valve cover.
After refilling the oil, run the engine for a few moments
while checking the engine's oU pressure. Make sure
there is no leakage around the new oil filter or from the
oil drain system, and stop the engine. Then, check the
quantity of oil with the dipstick. Fill to, but not over, the
high mark on the dipstick, should the engine require
additional oil.
