1998 4.3 , raw water cooling , no oil cooler
-milky tannish white thin oil from the pan
-thicker looking in valve cover area
-oil up a 1/2 quart
only 3 small droplets from spark plug in cylinder 2. plugs normal looking- not white.
-new head gaskets, riser and exhaust gaskets, intake manifold gasket.
-manifold and risers passed the acetone test( i know not 100% dependable at all) will prob end up doing a pressure test. off the boat
-So i have done the water jacket coolant pressure test (with the pressure dropping very slow, cant see needle move but it does from 10 to 5 over a half hour, )
-no sound from valve covers or carb, or dipstick.
-Is the thermostat supposed to be removed for this test?
-AND with loosing pressure at this slow rate an no air from carb or dipstick or valve covers, should i move on or is there a small leak, crack ( that prob is larger at operating temp)?
