Remember to check your mufflers! - Brock - 09-22-2017
My friend just sent me these pictures. He's been complaining for months to his boss that his truck had low boost and low power, mechanic and boss told him he was nuts.
Motor blew, rebuilt and still not properly running. They finally decided to change the mufflers and boom! She's running like a 6nz should be.....

What the hell? Were they using it as a shovel? What is that in there? Is that dirt and dust from say a dusty environment? WOW! Was this a weed burner or a regular stack?

This is a regular stack, twin stacks on a peterbilt 379. I think they were just on there a real long time.

Looks like they have dried coolant in muffler. Was engine thirsty before rebuild?
