One of the few DT's here is about an 09 with 300,000 miles on it. Driver said nothing about it when he came in Friday. Monday morning he reported a problem. It is running rough and makes a huffing noise at the air filter.
All the fluids are good and it smooths out at about 1300 RPM. First thought was a bad intake valve.
It has more blowby than desired but it is consistent. Exhaust flow at tail pipe is also consistent.
No active codes. Second thought is a worn exhaust cam lobe. Have not had time to get into it yet. Just wondering if anyone has experienced this problem? All help appreciated.
