Not too familer with this motor. 5.3l . My dad Has about 130k miles and hasnt gave any issues. Oil was 2 qt's low. My dad does the oil changes himself.
What should I look for besides the obvious leaks?(havent gotten under it yet.)
What are the common issues with these motors.
Other thought is it was just serviced at midas for shocks/brakes/tires/wheel bearing and maybe they drained a little oil out of it so he would come back, never know?
thanks in advance
