Ticking sound
I owe a 2001 Pontiac Bonneville with just over
164,000 miles. In the last couple of weeks I have
noticed a ticking sound coming from the engine. It
almost sounds like a rock in a tire or an alarm
clock. It increases with speed and slows when I let
off the gas. I've had several repairs in the last
couple of years but most recently would have been
the upper and lower intake, which was repaired
sometime in March I believe. Someone please help
cuz my dad and I can't seem to figure it out. He
thinks it might be something with the tappets and
maybe putting an additive in it would help the
situation but I just don't know.
