Hello everyone, I recently purchased a 1997 dodge ram 2500 with what I believe is a 12 valve engine. The truck was built in June of 1997. After looking up the VIN I noticed that the provider said that the engine was a 24 valve. I read online that I could have a 12 valve in a 24 valve block...

Who’s rebuilt their injectors with new shims and nozzles and how do you like it? My number 6 injector is slobbering. I can hear an injector knock and the exhaust port on #6 is a little wet. Praying it’s just diesel. Would nozzles and shims bring her back proper or would I be better off with a...

I'm having problems with my fuel/water separator. Every probably 4 to 6 months mine just starts leaking horribly. I've tried new O-rings and even going to the point of trying enough RTV to fix it. It just keeps coming back the only way I've found to fix it is just get a new filter. Anyone know...
