Oil pressure question
But I think that anywhere on the lower oil passage could be used to get a reading of oil pressure. I think you are on to something.. I have never thought of using those plugs. There is also another one near the rear of the block if you can not access the front one do to the accessories (alternator or Power Steering Pump).
I think the only problem is that the plug use a hex key to drive them in.. you would have to screw in the adapters afterwards. I someone could design a new plug with a threaded port on it.
