I changed my timing cover and now I have no oil pressure whatsoever. When I changed my timing cover I also changed the oil gears and made sure I lubed them up good with Vaseline. I also changed the oil and oil filter and now that i did these steps and also made sure everything was clean before I put it all back together and now that it is all put together in one piece I now have no oil pressure and I have no clue on what to do now if someone has had this same problem as me please guide me in the right direction on what to do next because I am losing my mind on this.

Have you confirmed this with a mechanical gauge? Does the engine start and run? When doing the cover, you have to disconnect the oil pressure sensor. We need to make sure that is reconnected. If it is, we need to hook up a mechanical gauge and check to make sure the vehicle gauge is correct.

If it is then I can only assume the gears are the issue unless you have a massive oil leak.

I attached the process on the gears just to see if you missed something in what you did when you replaced them.

Here is a guide on low oil pressure but again, we need to confirm this with a gauge. I also attached the process on how to perform this test. Let me know what you find. Thanks
