Hello guys,

I am very new to this board. I have a '97 C36.

Recently I notice that when in idle, I open the door and listen under the car, there is ticking/clicking noise. The noise is not very loud. Seems louder in the passanger side. If I rev the engine slowly, the noise slowly fades away, but come back again when idle. I am suspicious with the exhaust manifold or exhaust gasket.

I did some searching in this board regarding C36 noises, but seems like none fit my description very well.

I just get my serpentine belt changed and oil sensor. I believe I had this noise before the new belt.

Any info and help will be appreciated.

Thank you,
