I never had my oil pressure guage working. I was wiring it up I have the backlight working and all the wires ran an hooked up. When I turn the ignition on the gauge sets to 0 and when the motor is running the needle jacks up all the way on the gauge. My idiot light is working. Its a VDO gauge with VDO sending unit with a ground and a signal post. Any Ideas? Surely I don't have 80+ psi

Check pressure with a mechanical gauge to see actual pressure. You probably have a bad sender. |

or a bad ground. bad ground equals pegged guage |

is this the new motor? My buggy starts and idles with 85-90 psi till it warms up. When its cold it sits at 100 psi till it warms up witch takes a while at idle. |

I had a similar problem with summit gauges. They said to try n get your ground as close to the sending unit as possible. worked for me. |

Yes, I never had the gauge hooked up on my old motor to know the difference. Maybe I need to get it out of the garage and let it warm up! I can't let it run to long in the garage, the exhaust is to die for

If you dont check your oil pressure with a mechanical gauge at the port to know what you actual pres is your still just guessing. you dont know if there is a problem yet. |

Hyde's motors are good for oil pressure! On ef 'em blew my oil cooler apart and broke my autometer mechanical guage in the first 30 seconds of idling  I had to take a shim out of the relief after that. I'd rather have too much oil pressure than too little! He builds one hell of a motor

Yeah the gauge reads about 65-70. I'm going to get a mechanical gauge to double check. It will have to wait, I pick up some new rockers and need to make new pushrods. 1 step forward 2 steps back. |
