I have gotten some suggestions on how to take care of my car problem and I would like to get some input on these suggestions and decide which way I shall go.
One suggestion is to remove the oil pan and check if there is any blockage on the oil pump screen that could cause low oil pressure, and also check the oil pump and the bearing?s condition.
However, I was told it is probably a waste of time and money (a couple hundred dollars) for the above action. So here is another one which suggested an engine flush with Amsoil or Seafoam to remove any deposits if any, and then replace it with synthetic oil after the engine was cleaned. My concern is that since the car has a leak somewhere, would the engine flush cause more serious leaking problems?
In regard to the oil leak, I know people have been using a stop leak product for worn out seal problem. Just wondering if that will work for my case.
One approach is based on if the low oil pressure is basically a worn bearing problem (since the mechanic put a gauge in to directly measure the low oil pressure it is less likely to be a oil pump or blockage related issue), I could just try to change the oil with thicker oil to see if the oil pressure increases and then forego the oil pan and/or engine flush approaches.
I hope to get some input on these and I really appreciate your time and advice.
