HEY GUYS,
I HAVE A SMALL AMOUNT OF OIL COLLECTING IN THE MANIFOLD WELLS ON THE PASSENGER SIDE RIGHT NEAR THE FRONT TWO INJECTORS, DOES NOT LOOK LIKE ITS COMING FROM THE VALVE COVER, ANY HELP, ALSO IF THE RUNNERS WERE LEAKING WOULD IT CAUSE A ROUGH IDLE, ANY WAY TO TELL.

THANKS
ROBERT HILL

 

The oil is from the crank case vent or the pvc valve it is normal to have a little oil to get into the intake. If your runners are leaking the computer will not regester all the air that is coming into your engine therefore will run differently than if it was regestering all the air that was coming into the intake. It would also cause a vacum leak and cause the engine to run bad.
