So once my engine is warmed up, my oil pressure always dropped to zero. We assumed that it was the sender that was deffective so I replaced the sender yesterday but still got the same reading. I checked my pressure with a mechanic guage today and I still have oil pressure. So if its not my sender being faulty, why am I getting incorrect readings?

 

gauge could be out of wack...

As long as you maintain a minimum 10psi at idle and another 10psi per 1000RPM your fine.

 

Well i've got the digital dash so i dont really have a dash guage to be outta whack, but I guess since it is digital, that prolly increases the possibilities of whats screwing up.
