GOT EVERYTHING RUNNING FINE PUT NEW OIL PUMP & OIL PRESSURE SWITCH TUNE-UP PUT IN SEA -FOAM AND THEE DAM THING STARTED LOSING OIL PRESSURE HELP

Upper case is considered shouting in a forum :blink: . Sea Foam cleans out a lot of stuff, it may only be coincidence. I'd start with a new oil sending unit. A lot of us have low oil pressure readings and have been running that way for years. If it is not making noise you are holding enough pressure to satisfy the needs of the engine. I have a wet gauge and at idle it shows between 5 and 10 pounds at idle and then indicates approximately 10 pounds per 1000 RPM which is just fine. Also, in a high mileage engine it may help to go up in oil viscosity rating, I use 20w50.

Good luck,
