I have oil and water temperature sharing the same gauge just flick a switch to determine which you want a reading of. Lately my oil temperature has been running very high 100 to a 110 on normal road driving after about 20 miles ,my water temperature stays normal. I have replaced the sender which is fitted to the appolo tank over the weekend but just the same tonight. My engine is a k series vvc. The Cuborough sprint is coming up this weekend and I am bit worried. Does anybody have any suggestions what might have caused this to come on all of a sudden. Many thanks Aled
