I had a pinhole in my pressure line and it drove me crazy for a long time. I finally cleaned the whole engine compartment and then let it dry. I started the car and kept looking and still didn't see it until I had someone turn the steering wheel while I looked under the hood. I found where the oil was and then wiped it dry. Then kept looking until I found it. It was not an easy thing to find. It sure is nice to get that suff fixed. Good luck with it.
