If pan does not leak, it may after you remove it. Test pressure with a completely different unit First. That's what I would do. You can install a mechanical gauge in the engine compartment, no need for much plumbing for test. Mechanical gauge can go right into block, no sender. Electrical gauge needs sender. Mech gauge is $20 + brass fitting. Take out electric sender, take it and new gauge to hardware store, get adapter to fit both (engine hole and gauge). You can borrow a gauge from a motorcycle you have or ?. Make sure you know what pressure range is good for 235. Mount it so you can see it, start engine , read gauge. Then you will know what's up. Change oil after every 200 miles? Goodness gracious! WITH a filter? What a waste of natural resources! But you probably take it in to a recycler.
