When I accelerate I hear a ticking sound and if I let off the gas a little ot stops or quiets. It only happens when the car is in gear. Im not sure If its a lifter or my exaust because I have used sea foam to clean carbon out a couple thousand miles ago, But my muffler and resonator are very rusty and have chips in them but I dont smell exaust fumes.
My car has 160000 miles.
My car has an automatic transmission.
It sounds like the ticking you are describing may be the result of an exhaust gasket leak. When the exhaust gasket begins to fail, this may cause this type of ticking sound as the engine RPM’s increase. I would suggest having a professional from YourMechanic come to your location to take a look at the vehicle.
