Oil Sending Unit or Worse??

[twosocks]

Coming home, this evening, running approx. 65 mph, I noticed that my oil pressure was reading all the way to the left. Who knows how long it had been reading that but I didn't hear any valve noise and the temperature was correct.

When I came to my exit and stopped the needle rose to the first "low" mark and then increased more as I pulled away from the light but when approaching 45 to 50 mph, the needle dropped again.

If this is pump or engine related, shouldn't I be hearing some valve noise when the pressure reads to the left?

What is she idleing at? Could be your timing chain, if it's wore down a bit, broken pieces of the plastic chain guides, can be cloggin your oil pick up.

I only say that because i'm about to get my timing done, and sudden low pressure was a symptom. puttin a new oil/water pump in as well...

the 3.0 has a timing belt, not a chain.
is there anyway to check the pressure with some sort of external gauge to pinpoint the problem?
