For a while now I have been starting my Mattituck and waiting for 6 or 7 seconds to see ANY oil pressure.
Made me very nervous.
After some testing it turns out that the oil line contains air not oil and this acts like a big spring and on start up the oil has to flow that little tiny hole and compress the air before it shows pressure.
Over night of course the air gradually forces what little oil there is in the line back through the restrictor.
I took my restrictor out and bingo...Instant pressure on cranking.
Now one could argue that removing the restrictor is a bad idea in case the oil line failed but if your worried about that then you would never install the oil cooler.
The Dynon has plenty of signal dampening by itself apparently. The other option is to make sure the line is full of oil.
One sqwark down a couple more to go.
