I've got a 99 Civic EX and noticed a pretty bad oil leak in the upper left side of the engine (side that the radiator is on) I've replaced the valve cover gasket and it's still leaking. Even when the car hasn't been run for a few days it still leaks. Any ideas as to what that is?

 

If you mean the distributor side it's most likely the distributor rubber o-ring causing it. Just replace it.

 

 

As shown in the video VTEC solenoid is the other location.
