We purchased our car second hand in August of this year and it came with 33 near perfect photos but looks can be deceiving. It looked good but no one had done the maintence.
We were experiencing low
oil pressure and jumped to concluision about the pump being bad. The forums confirmed our fears and we were ready to pull the engine but a closer inspection showed the pan bolts were loose. Problem solved "Have
oil you will have pressure."
Track the problem, test and eliminate each component.
I am beginng to sound like Mr. Fixit
