Northbound, 20 minutes after departure from san jose reid hillview , engine oil pressure began to drop slowly into the yellow caution mark. I requested vectors to the closest airport for immediately landing from ATC. I was given vectors to livermore airport which was 8-10 miles south of our position. An emergency was not declared. Engine oil pressure continued to drop as I began my approach to land, but pressure never entered the red warning mark. The engine was never shut down. As I touched down, the plane began to skid to the left. Though the plane's nose was parallel with the runway centerline, it still skidded to the left. Correction was given and the plane skidded to the right. As the plane's speed decreased, the plane became more ctlable and I safely taxied off the runway. Post flight inspection revealed a broken propeller governor oil line which spewed oil out of the cowling across the plane belly. Also noticeable was oil on the two main and front landing gear. It appears the oil on the tires caused the plane to skid on landing. After the plane slowed I was able to control the skid.

Title: EMERGENCY LNDG, SKID ON CONTACT.
Narrative: NBOUND, 20 MINUTES AFTER DEP FROM SAN JOSE REID HILLVIEW , ENGINE OIL PRESSURE BEGAN TO DROP SLOWLY INTO THE YELLOW CAUTION MARK. I REQUESTED VECTORS TO THE CLOSEST AIRPORT FOR IMMEDIATELY LANDING FROM ATC. I WAS GIVEN VECTORS TO LIVERMORE ARPT WHICH WAS 8-10 MILES SOUTH OF OUR POSITION. AN EMER WAS NOT DECLARED. ENGINE OIL PRESSURE CONTINUED TO DROP AS I BEGAN MY APPROACH TO LAND, BUT PRESSURE NEVER ENTERED THE RED WARNING MARK. THE ENGINE WAS NEVER SHUT DOWN. AS I TOUCHED DOWN, THE PLANE BEGAN TO SKID TO THE LEFT. THOUGH THE PLANE'S NOSE WAS PARALLEL WITH THE RWY CENTERLINE, IT STILL SKIDDED TO THE LEFT. CORRECTION WAS GIVEN AND THE PLANE SKIDDED TO THE RIGHT. AS THE PLANE'S SPEED DECREASED, THE PLANE BECAME MORE CTLABLE AND I SAFELY TAXIED OFF THE RWY. POST FLT INSPECTION REVEALED A BROKEN PROP GOVERNOR OIL LINE WHICH SPEWED OIL OUT OF THE COWLING ACROSS THE PLANE BELLY. ALSO NOTICEABLE WAS OIL ON THE TWO MAIN AND FRONT LNDG GEAR. IT APPEARS THE OIL ON THE TIRES CAUSED THE PLANE TO SKID ON LNDG. AFTER THE PLANE SLOWED I WAS ABLE TO CONTROL THE SKID.
