Need some help please, Noticed antifreeze in bilge,
reilled antifreeze and noticed small amount of oil film
floating in bottle. ( cant see leak any where ) Took it
to a shop for repair , they said the pump was leaking.
They changed the pump , (why the oil in bottle ) took
the boat out ran it at 4000 rpm for a few min. and
checked it , the antifreeze is back in the bilge again
and the oil film is floating in bottle when i refilled it.
Will be back at shop monday. Any ideas ?
Rick

Check all hoses and connections, or head gasket is blown. check the thermostat as well.

Id say the second of the three, Thanks .

That would explain the oil film in the tank ( head gasket )
what would make it leak and where? maybe soft plug ?
I cant see where its comming from.
It seems to be in the area between the bottle and
the pump.

Had a leak on my 496 for a full season,finaly the hose to the water pump blew up antifreez everywhere,,replaced$1.25 clamp.

Got the boat fixed it was a rubber seal on a
heat exchanger hose.
I just want to say thanks to simmons marine /
simmons racing in franklin ohio /akron, for the
excellant job on the repairs.
Thanks again Jim for the great job.

Rick that still does not explain the oil in the bottle.

I had it check out and it wasnt oil , it was
something from the heat exchanger. my
mistake, am I glad !

The shop that did the work raced at st clair
( simmons racing ) did you see them ? I
thought you were there.
