1989 Dodge Ramcharger V8 Four Wheel Drive Automatic 52k miles
I have an 89 Ramcharger with a 360 TBI with 52k miles and a rebuilt transmission. It makes a thumping noise and I have had trouble pin pointing the cause. I have 3 different people tell me 3 different things. 1. Piston Slap. 2. Cracked Flex Plate. 3. Exhaust Leak. I ruled out exhaust leak after having a muffler shop look at it. I dont think its piston slap because its a thump and not a tick. Sticky Lifter Arm maybe? Anyways its driving me nuts its been doing this ever since Ive had it (4 months). It doesnt hesitate or stutter or show any signs of lack of power.
One thing I did notice is after Ive gotten my truck warmed up and using the heater it gets significantly louder and faster. Broken heater core perhaps? It does blow heat though.
have the same problem?
