the boat is a 88 Pontoon with an 3.7L (2 bbl mercarb) I noticed the other day that there was a slight bit of water in the oil. After running the boat in water and under load for the first time since i have had it, it lost between about 1/4" to 1/2" inch worth of water in the reservoir tank and the oil became milkier. So i obviously have a leak some where, or residual water in the oil from when i bought it.
I have taken it down and have the head off of it. It is currently getting machined and all the valves reseated. I have new gaskets for the head, intake, both exhaust gaskets, and the lifter cover and rocker cover. I talked to a very knowledgeable mechanic and he seamed to think that the leak wasn't coming from the head because if so i would have lost more water (this was pretaking the head off). He thought that i may have lost the water through the heat exchanger and the water in the oil was there before i bought the boat.
Its a long story but the people must have flooded the engine before i bought it. The water was high enough to fill the starter (i had no idea until 500 miles and a month later). So that may be it but i would rather go through this than keep changing the oil 10 times and then realize that it is the head.
Once i took the head off the #1 especially and #2 pistons were both "clean" and the 3 and 4 where coked up. With the sight of the i believe that it is the head gasket because if it were the intake or exhaust i would think that it would be in all of the cylinder instead of just two. Can anyone help me out? I am mechanically inclined but this engine has been a fight from day one. Any help will be greatly appreciated. THANKS
