Oil pumps are a very low-failure item, so unless someone has already diagnosed this as needing to be replaced, it would make more sense to start with the symptoms you're trying to solve.

The reason you can't find a video is this is definitely not a do-it-yourselfer job. You need to remove the front engine cover, which in itself is a pretty involved job, then the pump is built into that. You don't get a new oil pump for this engine. You measure the clearances between the gears and housing, then replace the parts that are worn excessively.

Rather than trying to find a video, you need to get a copy of the manufacturer's service manual, then read through the pages of instructions and line drawings to see if you still want to tackle this. Don't waste your money on Chiltons or Haynes manuals for this type of job. Those only cover things do-it-yourselfers can handle. You can also go to the top of this page, point to "Repair and Service", then click on "Manuals" to go to a site where you can buy a subscription for your car. That will cover the same things that are found in the manufacturer's service manual.
