Noise from Pulley Area

[ccognetta]

Ok, just getting the car back up and running. I am noticing a slight noise (light when you put a card in the spoke of a bike wheel) when the car is
running. Here's what I tried so far to eliminate to detect the noise..

1) Removed accessory belt, still have noise.
2) Disconnected the intercooler (thought the intercoolr
fan was hitting it or the bracket, move the bracket over.)
3) It appears the timing indicator is very close the crankshaft
wheel, don't know if that could make that type of noise.

Any other ideas? I hoping its not that metal cover the goes on the inside
of the timing cover and the end of the crank. I didn't think that could slide down enough to hit the timing chain??

Check inside the cam sensor cap. If all is well there, remove the fuel pump blockoff plate on the left side of the timing cover and use an inspection mirror to see if there's any nylon missing from the timing gear.

ok

What am I checking for inside the cap? Great Idea with the fuel pump block off plate!

When the cam sensor is about to fail, the metal piece inside starts hitting the sensor in the cap. It usually makes a tapping sound as the metal hits the plastic while the engine is running.

It was the fact that the crank sensor bracket was hitting ever so slightly, now its fixed
