Stop the engine. Wait approximately 15 minutes to let
the oil drain from the upper parts of the engine. Check
the oil level again.
Add oil as necessary to bring the oil level to the "H"
(High) mark on the dipstick.
Air Intake System
Inspect the intake piping for cracked hoses, loose
clamps, or punctures which can allow dirt and debris to
enter the engine.
Tighten or replace parts as necessary to make sure
the air intake system does not leak.
