First question:This is my first Cummins and it is totally stock right now with the AX flash. Periodically I will take it out and run WOT from a dead start up to 90 MPH or so just to blow it out, etc. My first question is, as the RPM approaches 2600-2700 in each gear, you hear what sounds like a "pinging" or timing advance knock (in a gas engine). It stays until the tranny shifts at 3000 RPM, the noise doesn't start again until the RPM gets back up to 2600 RPM. Is this normal or an indication that something needs to be looked at? Truck seems to run fine otherwise.
Second Question: I am driving up the ALCAN hwy this June to Fairbanks, AK. Do you get gouged on diesel prices compared to what you pay elsewhere? I figure diesel is going to be $4.50 per gallon in the US by then and just wondering what I can expect to pay in US dollars along the ALCAN?
