I also noticed loss of power on my 3126-E Caterpillar engine. I was wondering if maybe I had a exhaust leak because when I first start the coach I can here something like a tappet clicking or maybe an exhaust leak. I have been wondering how I can tell which it is.
I did change the fuel filter and the air filters when I got back from that trip. I have not used the coach since then so I am not sure if I got the power back. But I am still concerned about the clicking. It is hard to tell the difference between a lose tappet and an exhaust leak. Any thoughts on what to look for if it is a exhaust leak.
On a 7 percent grade about a mile long by the time I got to the top I was only doing 15 mph with the pedal to the medal.:S
