Your gauge or sender unit is likely to be faulty ;)

If it has no oil really, its to late :D

oil was only trickling out of the sender we thnk it was the reason the cam shaft broke ,at idle the guage did not read 10 psi , to scared to rev it would rather pull it apart again :? :? :?

Yep GU is a light only, no gauge, maybe Nissan gave up as they couldn't build a decent gauge. Camshaft breakage is a sign of no oil or a seriously warped head, I've got my old 2.8 on ebay siezed and all, it's up to $405 :P
