Hi, my engine blew out milkshake all over the top of the intake and lots in the bilge. I am trying to diagnose where it likley came from before oepning it up,
So, now what?
Does this sound like an intake manifold leak? Is there more I can check before I take off the intakes? I can pull the risers, they probably need attention as one was always getting a little warmer than the other over the years. The risers are what I would call an older version from 1997.
Any thoughts suggestions or guidance is very much appreciated.

- Engine has never had more than oil and plugs changed over the years.
- Fresh water only boat.
- Probably only 120 hrs on it, oil changed each season.
- I was able to drain out the sump best I could, change filter, add oil and a product to help break down the oil-water, engine runs like a top, powerful and steady, (OUT IOF THE WATER, for like 5 minutes).
- Ive plugged the two lines to the manifolds (nio sign of oil there)
- Ive disconnected the line to the water supply and added air to the line.
- I get air from both valve covers. Perhaps some from the oil check tube and perhaps some from the carb but not really sure at all.
- I do know no oil went into the water or is in the exhaust manifolds.
So, now what?
