Hi,
I would like to start out by saying what a great forum and I am Learning a lot. I only purchased my truck a couple of weeks ago so I am new cummins diesel engines. I do have a 1984 BJ42 Toyota Landcruiser with a 3B diesel, but its a lot different. My truck is a 2005 Ram Sport 3500 4x4 with 6 spd. tranny.
Over the past weekend I swithed all fluids to Amsoil synthetic and changed all filters? When I restarted the truck it sounded different. I am thinking that the amsoil synthetic oil quietened down the engine so now I can really hear the fuel injectors, It sounds like a loud knocking in the front of the engine and the fuel line to #1 Injector (I am assuming you call it #1, Its closest to the front of the engine) is pulsing a lot more than the others. Is this normal? I seen a post about this before, but there was no response. Its not smoking or running rough, but i took it for a run and it seemed like it had less power. I was thinking that this maybe from the fact that I used a DC air filter that looked a lot more restrictive than what the previous owner had installed ( A fram I think ?)I am nervous that I got dirt in the filter bowl when I changed the fuel filter because I filled the bowl with fuel, my dealers recommendation, before installing new filter. Thinking about this now it seems like a good way to ruin injectors by sending them some unfilterd fuel. Also could this be related to the threads I have been reading on cp3 timing? Is there a way to test injectors myself? The nearest dealer is 4 hours away.
Sorry for all the newbe questions.
Thanks for your help.
Neal
