I have a 2008 6.4 power stoke that I purchased towards the and of January. I'll change the oral and filter, change the fuel filters, change the air filter, and draiNed the water separator every couple of tanks of fuel. Sunday I heard what I thought was a squeaky belt tensioner but it went away after I drive for a while. today it came back but after checking the engine it seems to be coming from the rear rather than the front of the engine. I'm supposed to leave tomorrow on a 500 mile tripe in this truck! any input is appreciated.

If its coming from the back of the motor it could be a leaking up pipe. Check for soot on the firewall.

On a side note thats a good amount of miles. :thumb:

ok. chirping stopped, read the thread about the 6.4 tick, decided that's what it was and set out on the first 500 miles of my trip. truck performed flawlessly; till this morning. tick is back accompanied by a slight thumping that sounds like its resonating through the intake so I'm figuring it's the rocker arm tapping. figuring its a rocker arm or a lifter. damn again. anybody know a good diesel mechanic in augusta ga??
