WTF M8 ... No oil pressure?
God damn .. I fix one problem and then another one happens. This is on my S4 T2 Vert.
Well I was driving 30 miles to go to universal studios today .. then on the way back I noticed 0 pressure on my oil pressure gauge (stock one in cluster). So I put about 60 miles on with possibly no oil pressure.
Now what should I be looking at ? I know there is four possible culprits
1. Oil metering pump
2. Oil sending unit - the person that did my swap put in a high pressure racing beat one, so I don't think this is the problem
3. Oil lines are leaking
4. Gauge/sender is fuxored and just not reading
What should I look at and where should I look at it ?

1 and 3 are not valid causes.
Your sender could be bad. Your gauge could be bad. The wiring in between could be bad, or disconnected at the sender.
The engine would not be running if you had zero oil pressure...you get about 10-20 seconds under that condition before it locks up.
You could be suffering from LOW oil pressure, as in 5-15 at idle...this could be a blown out front cover o-ring.
You NEED a mechanical oil pressure gauge installed at the stock location (not permanently, just for testing) to actually see where you stand. You want to see 25+ at idle and 40+ above about 2500.
