It was only after looking at my new parts that i had a closer look at the aluminium part of the sump.
Those plugs had to be there for a reason . One could of been for internal machining but not the other one, no reason. Well both port directly in the flow line after the pump.
i have been told with very good authority they are commonly used.
Once the car is running we will be monitoring it to see how reactive and accurate they are
