I made the assumption that the spool valve gasket was the only source of the leak. I ended up replacing the vtec valve assy., after I replaced just the gasket. (The oil pressure switch was also leaking.)
I am now trying to track down a slow oil leak from the upper timing chain cover. I cleaned the engine and drove the car 20 miles and found no leak. 3 days later the area is oily. The valve cover gasket is ok. The power steering pump is ok. It could be leaking from the small 2 bolt cover near the p/steering pump. The bottom edge of this cover is oily. Has anyone else had this same problem?
