Customer Question
Started yesterday morning and...

Started yesterday morning and horrible noise .... like lifter sticking. Same thing this morning .... warning light says need to check oil pressure.

Mechanic's Assistant: Have you checked the oil? How old is your oil pump?

Oil changed and clean ... oil pump is as old as the vehicle.

Mechanic's Assistant: What is the model/year of your Chevy?

2001 Chevy Silverado ... 6 cylinder with nearly 250,000 miles. Working fine up until yesterday. Yesterday after warming up for nearly 10 minutes the noise went away.

Mechanic's Assistant: Are you fixing your Silverado yourself? What have you tried so far?

Nothing .... usually do most of the work myself but ... not sure about this one. Oil pump difficult to fix ?

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Don't think so ....
