I have a 2000 Cadillac catera car starts and run fine but oil pressure went to zero and red light came on and car shut down. Got it towed home started it back up and it has oil pressure. Is pump bad
Is pump bad or need to run thicker oil.
If needs thicker oil what would u
recommend. Thanks For ur help
That or the oil pump pickup screen is getting plugged up with sludge, but if the engine has been serviced properly sludge should not even be a problem. I had a Bronco once that would run down the road about 30 minutes then loose all oil pressure, shut it off for 10 minutes it would run another 30 then do the same thing, replaced the oil pump and screen , no more trouble.
