Replaced the head and timing belt and water pump. Now I have an oil leak on the passenger side rear of the motor. Already checked the oil pressure switch and vtec solenoid. I’m at a loss I have cleaned it and ran it at idle. It starts leaking when you drive it a lot. Any suggestions?

 

Valve cover and head gasket are what I would look at first. It my may be from the cylinder head replacement but you never know until you look at it.
