I winterized the boat early last fall, removed both screws that goes
behind the manifold, the two screws on each side on the block and the
inlet and outlet hoses(learned that with a marine mechanic). Have been
doing this for the last 4 years, no problem and this last winter was
mild down here in OK. Yesterday, first time I take the boat to the
lake and after a few hours in the lake, getting ready to load the boat
back home I noticed the engine beeping and almost cutting off on
idle. Opened the engine compartment and noticed oil and water mixed
(milky combination) flowing out of the top of the carburator area.
Talking about a shocking experience here!!! Pulled the dipstick and
the mix of oil and water is all the way to the top. I am praying for a
blown gasket, but all the posts I ready point to a crack on the
engine. Also I had to get something on the engine area a few minutes
before riding back to the dock and did not see any problems or oi
+water overflowing. So it seems like it happened on the way back to
the dock. But it could be running like that since we got to the lake.
I am not a mechanic, but I would think if I got the water out of the
block, manifolds and pump hoses, at least if it is a cracked engine,
it should not be in the block. What do you think. I saw a lot of water
come out of that engine. Where else would water be hidding enough to
crack the engine ? Or could it be something else ? I would appreciate
if you can share your thoughts. Thanks in advance.

3.0's are easy to winterize, there's not much to it. But still. I'm
wondeing in the engine has an internal crack in a cylinder wall.
You're is probably a raw water cooling system so no exhaust gas to
build in the heat exchange, so I'm thinking that some where there is
either a crak in the block or the head. I believe I'd take the head to
a quality machine shop and have it magnifluxed to see if there is any
internal damage, and if so, see if it can be re welded. Also you
should be able to tell in the gasket gave out as well.

while you have the head off, you'll be able to tell if there has been
water damage to a cylinder. But it sounds to me that you've got
something really major going down on you.

Can you think of the engine over heating at one point? And if it has.
it's possible that the main water pump is defective thus over heating
the engine regardless if the lower end impeller is working or not.

also, I've seen people run the alternator belt too loose causeing the
water punp to slip and not provide sufficient cooling. alot of
problems to look for.


good luck.

That sucks!!! But I did remove all the darn plugs and water pump
hoses, including the two ones in the block, saw the water run out on
both sides. Anyway, instead of speculating, I will ask what would be
the next steps to find out where the problem might be. Remove the
manifolds first to check them out ? Could the problem be there ? Any
idea of the cost of rebuilding this engine in a marine shop? I could
probably try to do it myself, but don't have the time.

Here is what I found out today. I noticed the alternator belt is so
loose that I can turn the alternator with my fingers. I overlooked
when starting it in the lake. Would this make more sense to cause the
engine to overheat since it appears that the water pump would not pump
any water into the engine ? I wonder if it cooked the head or if a
blown gasket would cause the mix. The boat was kept in an insulated
barn, all winter with cover on top and closed engine compartment.
Water was drained out of the block, manifolds and pump just by pulling
the plugs.

I'd say your winterization was done right and I would say that is the
main culprit. over heated engine due to a non functioning water pump.
I would say that the block is fine, but there are blown head gaskets
and possibly a cracked head. I dont' know what the marinas charge to
work on this stuff, but it is basically an automotive engine. So you
might talk to a local mechanic or garage that you would trust and see
if they could make the repairs. cost varies from shop to shop.

concerning water in the oil. Yes, and bad head gasket and/or cracked
head can do that. because the coolant channels in the head are
compromised where they now leak water into the oil chambers.

But I'd say that the heads need to go to a machine shop for
resurfacing and inspection.

But with what you've said, I'm ruling out a damaged block .

Thanks,

Yep, I just drained the oil+water mix, added new oil to avoid rust.
Tried to start the darn engine for a few seconds to remix with new oil
before redraining. Now I hear something new when starting the
ignition, a loud grinding noise on the back on the engine. I can't get
it to start. Decided not to force it. It rained here last night and
the water rose to the level of the starter since the oil mix clogged
up the drain plug, wonder if this is a new problem or if related to
the same issue. I will take it to a mechanic frind of mine and see if
he can pull the head out...

up the drain plug, wonder if this is a new problem or if related to
the same issue. I will take it to a mechanic *frind of mine and see if
he can pull the head out...- Hide quoted text -

Oh my goodness. The EXACT thing happened to my 4.3L 1997 (in a Regal
2100LSR) when I checked it out on the lake on July 2 (after having
just pulled it out of storage). Since the winterizing was done by the
guy who stored the boat, he is "checking the problem." I am wondering
if he actually got all of the water out in the winterizing (we live in
Montana).

PLEASE, when you identify the problem, please report back, or send me
an email at . Thanks.

I winterized the boat early last fall, removed both screws that goes
behind the manifold, the two screws on each side on the block and the
inlet and outlet hoses(learned that with a marine mechanic). Have been
doing this for the last 4 years, no problem and this last winter was
mild down here in OK. Yesterday, first time I take the boat to the
lake and after a few hours in the lake, getting ready to load the boat
back home I noticed the engine beeping and almost cutting off on
idle. *Opened the engine compartment and noticed oil and water mixed
(milky combination) flowing out of the top of the carburator area.
Talking about a shocking experience here!!! Pulled the dipstick and
the mix of oil and water is all the way to the top. I am praying for a
blown gasket, but all the posts I ready point to a crack on the
engine. Also I had to get something on the engine area a few minutes
before riding back to the dock and did not see any problems or oi
+water overflowing. So it seems like it happened on the way back to
the dock. But it could be running like that since we got to the lake.
I am not a mechanic, but I would think if I got the water out of the
block, manifolds and pump hoses, at least if it is a cracked engine,
it should not be in the block. What do you think. I saw a lot of water
come out of that engine. Where else would water be hidding enough to
crack the engine ? Or could it be something else ? *I would appreciate
if you can share your thoughts. Thanks in advance.

3.0's are easy to winterize, there's not much to it. But still. I'm
wondeing in the engine has an internal crack in a cylinder wall.
You're is probably a raw water cooling system so no exhaust gas to
build in the heat exchange, so I'm thinking that some where there is
either a crak in the block or the head. I believe I'd take the head to
a quality machine shop and have it magnifluxed to see if there is any
internal damage, and if so, see if it can be re welded. Also you
should be able to tell in the gasket gave out as well.

*while you have the head off, you'll be able to tell if there has been
water damage to a cylinder. But it sounds to me that you've got
something really major going down on you.

Can you think of the engine over heating at one point? And if it has.
it's possible that the main water pump is defective thus over heating
the engine regardless if the lower end impeller is working or not.

also, I've seen people run the alternator belt too loose causeing the
water punp to slip and not provide sufficient cooling. *alot of
problems to look for.

good luck.

OOPS! I'm sorry, but you mentioned 4.3 instead of 3.0.

Now I am thinking that you may have an internal crack in the block.- Hide quoted text -

Here is what I found out today. I noticed the alternator belt is so
loose that I can turn the alternator with my fingers. I overlooked
when starting it in the lake. Would this make more sense to cause the
engine to overheat since it appears that the water pump would not pump
any water into the engine ? I wonder if it cooked the head or *if a
blown gasket would cause the mix. The boat was kept in an insulated
barn, all winter with cover on top and closed engine compartment.
Water was drained out of the block, manifolds and pump just by pulling
the plugs.

BTW,I'd say that marine shops (over automotive) are probably used to
this because it's actually not uncommon. and then when thinking about
it, dealing with the manifolds etc. a marine shop would probably know
where to go with it, what to do to it and how to do it, due to
experience.


Good job, Tim.
