    Oil Pressure Gauge Momentarily Drops to Zero???

    First - this forum is great - thanks to all who contribute!

    I've had my 98 catera for almost about 8 months. Since I've owned it, the oil pressure gauge will suddenly drop to zero for a few seconds, then pop right back up to normal. I seem to notice it most while driving at highway speeds; and it does it fairly regularly.

    I'm not too concerned - its done it for 8 months, it runs fine, its been through several oil/filter changes, no warning lights, oil/coolant looks fine - no worries right???

    Anyone experienced this or have any ideas what the cause? (I've seen the posts about low oil pressure at idle - this is different - it reads normal while driving, then drops to zero, then pops back up to normal)

    Thanks!

    it could be the sending unit might be messing up not really to sure but as long as the oil pressure is still there I would not worry to much about it.
