" Jerry.... In response to you
" Jerry.... In response to your questions which I have copied here:
Q: Does the warning horn tell me the pump is not getting oil or not outputting oil?
A: The warning horn will sound off every other second if... 1 - The oil side of the VRO malfunctions resulting in a improper oil supply. 2 - A air leak develops anywhere between the oil supply and the VRO pump. 3 - A oil restriction develops anywhere between the oil supply and the VRO pump.
Q: Should I be concerned with VRO failing on a 11 yr old motor?
A: Not necessarily. However, take a good look at the electrical wiring that extends from the back of the VRO. Follow it to the rubber connector plug. If it has only three (3) wires, it is the old type VRO and is not dependable. If four (4) wires, it's the newer type and should be reliable.
Q: If I remove it and mix the oil will the over heat warning still work?
A: The overheating sensor is a completely different part of the wiring system and will not be affected (it will still work).
NOTE... It is not necessary to actually remove the VRO pump to accomplish the above. Simply cut and plug the oil line leading to the VRO (at the engine). This prevents air from being drawn into the oil side of the VRO and in effect converts the VRO to a fuel pump. Also simply disconnect the rubber plug wiring connecter mentioned above as the oil warning would no longer be needed.
Q: Will the motor run as well as it does now?
A: There would be no change in the performance of the engine. It would run as well as ever, just as long as you remember to add a 50/1 oil mixture to your fuel. (Forget one time and goodbye powerhead!)
NOTE... If you have the old type warning horn that doesn't sound off momentary every time you turn the ignition key on, you can test the horn as follows by... turn the ignition key to the on position so that power (12v) is flowing through the system as it should be. Do not start the engine! Find the TAN wire that extends out of the cylinder head (overheat sensor). Ground that wire out. Grounding that wire completes the warning horn electrical circuit and the horn should sound off. If it does not, you have no warning system (Find Out Why).
