We have a slow leak where the connection from the 'out' side of the oil filter meets the oil cooler. She's holding oil pressure and doesn't seem to be losing an excessive amount of oil (ran for 2 hrs today and noticed just a small drop on the stick when we got back to the dock). I tried to tighten the nut where the leak is originating, but it's tight enough not to budge. Any ideas??
Got to use a tubing wrench on those fittings so it can be cranked down without rounding flats.
If it is real tight, it might be a line fracture.
Take off the line and inspect.
Remember, once the flats are rounded, out come the vice grips.
Also put an open end on the flats of the fitting soldered to the heat exchanger. I sold more than one expensive heat exchanger after that fittings joint was fractured from twisting.
