hi lawson,
If your getting water into a cylinder then you could have a blown head
gasket. Blown head gaskets are common if you overheated your engine. Sign of
a blown head gasket with water getting into a cylinder is fog like white
smoke coming from exhaust. Sometimes a blown head gasket could only leak
water into the oil. Then when you check the oil you will see a mixture of
water and oil looks like a light brown or white-ish. I am speaking about
cars now... cause marine applications are similar I believe it is basically
the same. Water in oil can also be caused by condensation. I had
condensation on my truck engine. There was indication of water in the oil
but not enough to be a blown head gasket. What turned out to be the problem
was that the vacuum tube on the carburetor was plugged with carbon. The
crank case on an engine must breath, otherwise - condensation. I took a
drill and by hand used it to ream out the vacuum tube and problem was
solved. Also later I removed the carburetor and the bottom of it was covered
with carbon. PCV valve - PCV means positive crankcase ventilation. This
valve uses vacuum from the intake manifold to draw the fumes from the
crankcase. Symptoms of a faulty PCV valve are poor idle and excessive
pressure in the crankcase.
And also in my case - condensation.
Now if there is an indication of oil in your water
1.Crack in the head allowing pressurized oil to leak into the water jacket
2.Crack in the block...
3.Bad headgasket - the pressurized oil passages to the camshafts cross from
the block to the heads at the front (pulley side of the engine). The oil
pressure typically will be higher than the coolant pressure. A blown head
gasket (or pulled head bolt threads) could allow the oil to cross over.
I got the 3 answers off the internet for oil in coolant.
my suggestion... you know that you overheated your engine... try a
compression check first. Buy a compression tester - the screw in type - not
the one with the rubber end. I got mine at kragen for 29 dollars. Then mark
all the spark plug wires with a piece of tape and number them and then
remove all the plugs. Attach the compression tester and turn the engine 4
revolutions. Write down your results and which cylinder it corresponds to.

Subject: Sal****er Trouble


It appears sal****er has somehow got into my motor. The boat is a28'
twin.Last summer it over heated, we waited till it cooled off,added water
and then went back to the finger and tied up.It was used sparingly but
without incident,then came Juan.I was changing thermostats this spring
when
it became evident there was a problem.The anti freeze had turned to
toothpaste coloured crysallized substance.We used a product called Salt X
which has certainly helped.The motor has a closed fresh water system so
after doing a visual check,I took the expansion chamber off and had it
tested.It was ok, but now I'm lost.The motor when last used worked fine.No
miss or skips and no increased motor noise from the wet exhaust system.I
would be most gratefull for your opinions and directions..........Thanks

hi lawson,
also if your going to turn your engine - if you have a fresh water impeller
on your engine you have to hook up a water supply to your engine your crank
it in the water.
