Ok so I've said it before. I'm new to diesel.
My question is what are normal noises?
When the motor is under stress, ie : towing trailer up hill at slow speeds,
seems like alot of clacking and knocking going on.
Yep that's what they sound don't lug it make her work you will see she will run better but don't over rev it as a habit but diesel are built to work and the better they run within reason
