re: How do you do a manual oil pressure check?
Remove oil PSI switch, screw in hose on pressure gauge. Will need an adapter to match threads, may have to buy one in the brake parts blister pack aisle. Expect 10+ at idle, 50 at revved up. In a D1, 40 when revved up. My 187K D1 makes 44 PSI hot and I'm happy with it.
