so i'm almost done moving into my new rental house. i've been using my truck more than usual. it started making a loud bang, rattle, knocking noise. it's not consistent or rhythmic. but the noise does go faster with RPM. it only makes the noise when i'm accelerating or reving the engine in neutral. the new noise seems to be louder when the engine is cold. but it still does it after pulling an 8k lb trailer 60 miles. i can hear the knocking clearly in the cab when driving. but i can't hear the new noise over all the other noises when reving it from under the hood.
since i've had to use the truck i've been driving it despite the nervous feeling this noise is giving me. and i've noticed that the truck seems to smoke more on start up the last 2 starts. it's blue smoke so i assume it's not cavitation /coolant.
the SCA's are good and have been since this truck got it's second engine. i'm not losing enough oil to see on the dip stick. i'm not losing any coolant. the truck isn't down on power. it still idles beautifully. engine has 160k on it. i think the fuel system is original to the engine. i have no way to check timing, fuel injectors, fuel pressure, cylinder pressure. my pyrometer and boost gauges are in a box somewhere.
help. i'm worried i'm screwing something up driving it and i have a 700 mile trip coming up on memorial day weekend.
