Driving along tonight i had the oil warning light come on, i slowed down and managed to leave the road after about 1500 yards.

engine sounded fine and i suspected a faulty sender. I first checked the oil level which was ok and then noticed the rubber seal in the oil cap was gone.

gone where? Into the oil tank and over the feed hole to the engine causing a total loss of oil pressure.

i removed the tank and oil and fished out the offending split rubber seal. Refitted tank and refilled oil and started engine to my relief oil light went out instantly and engine sounds, runs and performs perfectly. Hope no lasting damage was sustained.

My point is please check the condition of the rubber seal in your oil tank cap. If its in any way split or swollen get it sorted before any damage can occur.
