its a lot! 10 seconds of half throttle and there is a puddle under the truck. I moved the truck out of the yard to parking lot so I can work on it and there is a trail of oil all the way. I was in first and second gear light throttle all the way. truck smokes a lot too if I give it throttle. and I noticed oil around the up-pipes. so piston rings could be worn out?
got a code about fuel injector pressure valid but below normal operating range or something like that! this truck has turned into a real problem! thanks for the help guys!
