1996 Chevrolet Lumina Question: Failed Oil Pump



Visitor, 3.4L V6, Garden Grove, CA, May 23, 2010, 23:09

The car stalled while driving. Repair shop says there's no oil pressure so oil pump must have failed and needs replacing. $750. Q: How common is oil pump failure and can it be clogged oil galleries? The oil is very dirty, I don't know when my son last changed it.

    it is not a common failure but not changing the oil can cause all kinds of failures.
    with dirty oil, any passage could be clogged with sludge

    Could it cause zero oil pressure? And can it be flushed out instead of paying $750 plus? They may find other things wrong after replacing it?
