190e 1.8 tapping???
As I drove off this morning from a cold startup, I noticed a faint tapping sound (sewing-machine like) with the accelerator pushed.
It gets fainter and disappears when I release the accelerator (with car moving).
While stationary, with the accelerator pushed, it's not there. When I drive off, it's there again on acceleration.
After about 5-10mins of driving, it's gone.
Today, however, the tapping wasn't apparent in the morning. In the afternoon, after 45 minutes of driving, I heard it on the highway for about 3 mins before it disappeared.
Doesn't seem like the timing chain to me coz it's not apparent at all times. Besides, there are double row timing chains on my 1.8 so I guess I need'nt worry about them, right?
Lifters?The tapping is driving me crazy...
