1988 Crusader 454 model 350 is reading 35 psi on port and 40 psi on starboard when running at 2500 rpm. Is this normal oil pressure when warmed up. What weight oil should I be using? Thank you again guys! |

Ayuh,.....
A Chevy motor will run Just Fine if it's carrying a minimum of 10psi per 1000rpms..... |

Thanx Bondo,
We purchased the boat a year ago. It was hit in the port stern on June 1, 2007. We just got it back on Monday. It has been a long year. Now I just want to do proper maintainence so I don't miss another boating season. |

Sounds in the right range. Think mine run 30-40 at 3000 rpm and drop lower at idle maybe to 20?
Use straight 30 weight. I use the Penzoil Marine grade 30W. |

Can the oil pressure be too high? Mine runs about 45psi at 3200rpms.(Twin 454s (1997)). |

That pressure is not too high. On startup, mine usually peak about 50-55 and once warmed up, a steady 45 |

Yea, my engines are like Als. 50's at start up, then 45-50 depending on the engine RPM. Good to know that they can go lower, and it doesn't mean something serious is up! I have learned so much about my engines through this forum. |
