heat and oil preasure gauges work for about 15 minutes then heat goes all way to hot, oil goes to no preassure then both start working againg for short time, any suggestions what would be the problem,?thanks
I would highly suggest, as did robert beck, that you remove and clean all your ground connections.
Simply checking for tightness, or lack of, will not suffice.
Bad grounds are like searching for a ghost.
At the very least you should go and re-torque all your grounds.
