Water in my Oil Update

[98outback]

Well after doing testing adn narrowing it down they came to the conclusion that the head gasket needed to be replaced. While doing this they visually inspected the head on the starboard side of the engine. Well after it was all put back together and ran on the hose it is still getting water in the oil once the boat has warmed up. They now believe the head has a crack in it that was not visible so they are sending it to get magna fluxed. SO i guess even here in florida I am going to have to start using anitfreeze when I winterize. Who would have thought. They are atleast saying it would be considered freeze damage if the head or block has a crack in it so my insurance will take care of it.

Real sorry to hear it, 98. So you did winterize it and u still got freeze damage??

[kaneboats]

Sorry to hear it too. So glad you have the freeze coverage.

I did winterize it except for running anti freeze in it. I always did my outback teh same way and never had any problems. I think it is because here in jax we had 10 - 11 days straight that it never got above freezing which is odd for florida.

You don't need antifreeze but you need to ensure all of the water is out prior to the cold weather. Engine draining is the easiest and should never be a problem. Get rid of any petcocks as they trap debris and sand. My concern with winterization is around the engine water pump and I will put some antifreeze in the pump area.

he is right if it was drained before the cold weather you don't need antifreeze. so why do you think the head cracked? That would be the last to crack if it was drained incompletely ii would think! and double the petcock thing and always poke a wire in the drain as they get blocked with rust. now i'm curious . oh and do you have a diff boat now or still the outback?

[98outback]

I dont know to much about engines as far as what goes first. It is at the dealer right now. I have a supra ssv with the 5.7tbi now. I actually removed the petcocks and put soild plugs so I the hole is completely open when I removed them.

[98outback]

The dealer called me today and said that my heads are good according to the machine shop after they were magna fluxed. So now they need to look more into the engine. They original said one cylinder on the starboard side had low compression so that meant it was the head gasket. They have now replaced the riser gaskets, manifold gaskets, head gaskets and now had the heads inspected. I dont know much about engines but what else could it be now other than the block itself? Is there a way to test the block with out removing it from the boat or test each cylinder for cracks? This is becoming a long process. I hoped to have the boat back by memorial day weekend at the latest but that isnt going to happen now.

[mmandley]

Only other way i can really think water can get in the oil is if the cylinder head its self cracked. When you drain the block that's what you are looking at in that little hole, the cylinder walls.

It should go without saying, but the heads or the block could be warped. Most of the time, that happens when the engine overheats, but freezing water is extremely powerful. A precise straightedge can be used to check it, but that isn't the best way. Pulling the engine and breaking it down to have the block magna-fluxed is labor intensive.

Maybe it is time to check with your insurance company. It may be cheaper to replace the engine with a new one.
