Water in my omc chevy 350 engine?

Question

I have water in my omc 350 engine. what could be the cause of that? The engine is in an 89 bayliner.

Answer 1

Very common causes are:

1.  Bad head gasket.

2.  Bad intake gasket.

3.  Cracked block (intake valley is common after a freeze)

Pull the intake first, look for signs of tracking on the gasket.  It's a fast and cheap fix.  Replace it and run a while, then check oil.  While it's apart, look for cracks in the intake valley.  You'll notice them, but they make be faint lines.

Good luck.  I have experienced both the cracked block scenario and the bad intake gasket scenario.  Pray for the intake gasket problem.

Answer 3

head gasket or worse stillblown head but that's unlikely

Answer 4

Why?? Bad gaskets or blown seals--the fact is--YOU NEED A GOOD MECHANIC--if a seal or gasket is gone--chances are you need to do a lot of other relavent work to avoid other troubles that will happen soon. It never is just one thing wrong.

Answer 5

Driving on the water would do that. It sorta gets pumped through there to cool the engine.

Answer 6

Could be a blown head gasket  or a cracked block
