I have an oil leak above the fuil injection air intake. I can't see under the fuil injection unit to locate it and it is getting worse. It started about one month ago as a very small drip when I first shut the engine off, now it is leaking for several minutes. It doesn,t appear to be leaking when running but who knows.
Don't know where the oil pressure warning switch is on your car, but for a <$10 part that takes 3 minutes to change out, that is always the first thing I suspect on an external oil leak from the head. Next would be the valve cover gasket. Good luck! HTH
