Hello, the vehicle engine do produce noise for some seconds when started in the morning or whenever the vehicle is cooled. I knew that the problem is that the oil pump is not pumping as early as possible cause friction to occur in the moving parts. I have changed the engine oil and filter the problem still persist. How can it be fixed?

Good morning,

Can you upload a video of the noise so I can hear if it is lifters on the top end or bearings on the lower end of the car.

Good chance it is the pump as the internal check valve may be bleeding off and draining the oil passage of all oil.

Worse case scenario is that the main and rod bearings may have too much play causing the noise.
