Hello,
Maybe someone can help... I have a 94 Pontiac Bonneville (3.8 liter V-6). Oil pressure is down to almost zero with the "check" gauges alarm sounding off. I had a mechanic look at it and did his diagnostics. After an oil change and measuring with a manual gauge there is hardly no pressure. I know there are many causes, but can someone please enlighten me on the most common ones??
Thank you,
Boss
