Oil Leak under Pressure
 

I have a 2000 accord ex 190K and i have replaced the egr valve, valve cover gasket, thermostat and changed the oil. I noticed the other day that I have an oil leak only when the engine is on. No other time oil is leaking.

From what I can tell it looks as if it is leaking from the center of the car. No oil leak dye has been added.

What do you suggest?

is it leaking from above the oil filter?

There is the oil pressure sensor there.

Suggest elevating car on ramps and getting under w/ engine idling to ID leak location. Oil pressure switch is a good possibility, but oil pan, or valve cover could also be the culprit.

good luck
