1. Is anyone aware of a way to verify adequate oil pressure on a 2016 - 2020 Polaris 110cc efi engine? 

2. If there a way to verify oil is reaching the valve assembly? 

3. Where are the oil passages located in the top end? 

4. Is it possible to remove the valve cover to inspect, without effecting the head gasket? 

Reason for the questions is due to excessive sludge in the engine, and need to verify oil is traveling throughout the engine. 

I purchased a 2020 Polaris Outlaw 110cc as a project. Can't wait to share my experience and have a resource for alternative ideas.
