Volvo U.P. 170 HP I/O 226 Cubic Inch Engine - MARINE - WATER IN OIL?

Question

A friend has a boat with two Volvo engines for his I/O drives. One engine has water in the oil and he has not been able to trace the cause.

Can you provide any solutions? He is quite able to do a lot of the work himself.

He is also interested to know if there might be any identical engines for sale that he could use to replace this one.

Thanks.

Answer 1

head gasket or some other gasket that is blown or unseated.... why does he think there is water in the oil?? smoke???  that would indicate that there is oil in the fuel...

Answer 2

I had a similar setup and it turned out to be a Buick 6 Cylinder...water inthe oil can be caused by several things, blown head gasket, cracked or corroded exhaust manifold... Is this a closed fresh water cooling system, or a raw water cooled engine?....

Answer 3

Sounds like a bad head gasket.

Keep your fingers crossed that it is not a cracked block.

Answer 4

All marine engines have external oil coolers, if water is left in the cooler during the winter they will freeze and burst internally which will let water in the oil lines.

Answer 5

I would suspect a blown Head Gasket or possibly a cracked head, as for a replacement engine I would try Jasper Engine,s to see if they could help.

Answer 6

You won't be able to find this leak, its inside the engine.  The water jackets wear down in time from corrosion, and water is now leaking past the jackets and into the crankcase.  If the engine runds fine otherwise, I would ignore it for now and do regular oil changes throughout the season.  There really is no repair, just a new engine.  But it may run fine for many more years.
