Some time ago, my oil pressure would intermittently drop to zero and then come back. Decided to change out the sender with one I bought at a local auto supply place. Could not get my wrenches to work in the tight area at the back of the engine and with little personal time (at that time) I decided to take it to the shop. After the shop replaced it, they told me the old was leaking bad, the travel on my dash gage was significantly limited for some reason and the motor had good oil...
