| Post subject: | Oil pump price |
Anyone tried to buy an oil pump lately? I am seeing prices from $55 to $75 USD. The last time I got one it was about $30. That's 100-150% more!!! Got a better source? |

And the bad part is they aren't any better...I already lost my last engine to a new melling standard pump... -D.Idiot |

Never use the drive gear that comes on today's new aftermarket oil pumps... it's just not worth the risk. Swap a good wear pattern gear off a used factory oil pump or get a case hardened gear. Loosing an engine to a low quality oil pump drive gear is never any fun. DD |

Does anyone still sell the oil pump rebuild kits here? As long as you have to pull the gear off a person might as well rebuild it. I see that Pentastar does but 135.00 AUD plus the ride is pricey. It would be 144.50 US plus freight due to the dollar being so low. |

The bad part is the gear was fine...the pump was packed with vaseline and upon removal/autopsy it was full of oil and the passages were clear...the rotor and ring just failed to make any oil pressure...hard to check clearances now since it injested some nice chunks and pitted the living crap out of the guts...Swap a good wear pattern gear off a used factory oil pump or get a case hardened gear. Loosing an engine to a low quality oil pump drive gear is never any fun. Have a pile of stocker pumps i'll be looking pretty hard at next. -D.Idiot |

Could that pump gear drive or the shaft pressed into rotor not tight enough and slip at higher PSI especially when pump and oil is heated up enough? Cheers, Wizard |

I have seen a number of oil pumps where the gear or impeller spins on the shaft... then the pump makes little to no pressure. This is hard to diagnose when the impeller 'head' start slipping, when the drive gear end spins, the gear is usually pulled right off the shaft. This tends to happen when metal pieces get past the pick-up screen and into the pump, jamming the impeller. When I see this happen, I am often looking thru the engine for where the metal pieces came from and how they got past the screen. DD |

I have seen where the pickup is full of dried-out carbon deposits. They form right in the screen, so you can't see any place where they "got in". |
