Tech-GeeK1500
I'm Awesome
So I got a code for a lean bank 2 (P0174) and my truck was running terribly. I could barely get it backed out of the drive, ran rough, pinged and stumbled, no power at all. I pulled the intake to find the spider leaking, lots of raw fuel in the intake runners which confuses me about a lean code. After breaker my heater outlet and cracking the lower intake, I just decided to pull it along with the heads. My passenger side valves are decent looking but black with carbon build up. I pull the driver side and my exhaust valves are white with an odd build up on them. The truck is a 1998 K1500 with the 5.0L engine. I didnt notice any blown areas of either head gasket. Also when the truck would run there was some white smoke on start up and it always smelled of raw fuel strongly when running.
