Tapping sound

[bsdlinux]

Is there anyhting in the oil pump that could or would make a knocking or tapping sound when warm.

Oil pressure is great 25@idle and 70-75@cruise.

All those gurus out there, someone is bound to have a reply.

You sure it aint something else like the cam sensor?

scottyb - Yes I have. I did not pull the sensor out but did pull up an it and it did move up a little. I am not sure what clearances are required. I will probably go ahead and check it out. I can feel the tapping on the Cam Sensor cover and the oil pump area but not anywhere in the valvetrain. I have also checked for a flat lobe, everything ok there.

Damn thing is driving me nuts.

My cam sensor has been making noise since I've owned the car, 2 years and 20k miles. My buddy even commented about the "valve noise" when I bought it, but extensive "screwdriver stethoscope" research turned up no significant noise except the deafening sound on the cam sensor cap. I can hear it come and go while driving, like an on-off switch. I finally yanked it last weekend to see what the deal was. It makes noise just by rotating it back and forth by hand! The play in mine was over .03, and I found a thread here where it was suggested that it should be ~ .015 or less. The noise is internal so I'm not going to bother shimming it, I'm just planning to get a new one. I suspect that shimming it MAY help, but only short term.

FWIW.
