Milkshake In My 5.0 And I Got It Out ***Update***

[Alpheus]

I just bought a 91 Baylner Capri 2050 with Mercruiser 5.0 I/O Alpha 1 gen II outdrive. I got the boat real cheap because the previous owner sais that it has a blown head gasket. I checked the dipstick and sure enough there is a milkshake in the oil pan. I know that this does not automatically indicate a blown head gasket it could be something else that failed and let the water in the crankcase. The owner said he just put it in the water and drove in a no wake zone for about 15 minutes and once he opened it up to WOT he said the engine immediately lost power and shut off. I got the boat home yesterday and went to suck out the old oil and I got about 2 cups of water and white sludge but that's it. The milkshake is to thick for my pump to suck out. Anyone know of any solutions to diluting this stuff to get it out? I was thinking kerosene would maybe thin this stuff out enough to get it out, but I don't know. This boat is in real good condition having a new deck,carpet and upholstery redone,so I want to get her running. Any input would be greatly appreciated...

I doubt you have a bad head gasket, that's what everybody hopes, but I have NEVER seen it cause the problem you have.
I would bet money you have a cracked block from freezing and not being winterized. All to common of a problem.
Before you spend much time trying to get the oil out. I would be pressure checking the block and probably pulling the intake and looking for cracks around the lifters.

Re: Milkshake In My 5.0 And Cant Get It Out.

On my past 2 boats with merc v8's I put a fram sure drain in. You drain the oil from the pan (first time is a pain), but then you put in a quick connect in place of the stock drain plug. I then would hook up the fram quick connect that I had adapted to some tubing. I could pump out of the bottom. Oil changes were fast and I was pretty confident I got it all, never was sure when I sucked it thru the dipstick tube. So you can probably get to the drain plug, it might be a bear.
Thanks, Dave

Ayuh,... A Putty Knife works pretty good,... After you get the motor on a Stand....
I'd just toss it in the Scrap pile....
Like Don said,... It's a Frost Busted block,... You need a New motor...

Re: Milkshake In My 5.0 And Cant Get It Out.

I agree with the cracked block theory. It takes longer then 15 minutes of idle to turn oil into milkshake with a "blown head gasket." It would have to be one hell of a gasket failure.

Re: Milkshake In My 5.0 And Cant Get It Out.

I would agree with a cracked block if I lived a little more north than where I live and the boat came from Texas last year. It was not winterized because it was used year round. Ya it gets cold here but rarely freezes. Also right after the engine quit the air cleaner was removed and it had shot milkshake out of the carb. This tells me that water and oil got into the combustion chamber or in the intake manifold. I'm not ruling out cracked block, but don't jump to conclusions. This is not my first boat. I'm just asking if this has happened before and if there are any tricks to getting out the milkshake. I have no problems removing the engine or replacing it if need be. I work on airplanes for a living and I find working on boats is a bit easier IMO...

Yes, it's happened before. Due to cracked blocks.
You can change head gaskets all you want, but you still have a cracked block. I used to work on airplanes too, they don't have raw water cooling systems either.

Re: Milkshake In My 5.0 And Cant Get It Out.

You can tinker with it, but I think your plan B should be that you will need a new motor. Good time to upgrade to a 350. Since you got the boat cheap, putting in a motor should still have you in pretty good shape.

I think everybody who has a milkshake hopes for a head gasket, including me. I had the experience in a car. I changed head gaskets and still had the shake, and this was in SE Tenn, N Ga, where it doesn't freeze much either.

On another note, if the motor "shut off" you've probably got other major problems, even if it was a head gasket.

Good luck

P.S. Drain the oil through the pan like a man

Re: Milkshake In My 5.0 And Cant Get It Out.

Not sure about Mercruiser, but in my previous Volvo I had lost an o-ring at the oil cooler. It created the same results but was a whole lot cheaper and easier to fix than a new engine. Hopefully it could be something like this to give you a bit of optimism...

Thats fine but don't jump to conclusions that just because things freeze in your neck of the woods doesn't mean it happens every where. I just don't work on airplanes I design the avionics systems for them. I'm not going to anchor my engine without a proper tear down and diagnosis of the problem. I have seen cracked intake manifold load the oil pan with water too...

Re: Milkshake In My 5.0 And Cant Get It Out.

First of all, there is no mention as to were you are located. So if it would freeze or not, who knows.
If you know what to look for, then look. Why expect people that have no clue where you are or where the boat has been for the last few years, or what the weather has been over that time to answer why you have that much water in your oil. I'm the only one here that had a crystal ball, and the danged thing is broken.

Re: Milkshake In My 5.0 And Cant Get It Out.

I think what Alpheus want is some OPTIONS as to what can cause this so he can check on each methodically, correct me if I am wrong
Firstly ignore the naysayers and MrBlackwells.....one liners dont help..they sound negative...people need choices and positives...there's already enough negative in the world....I am not discounting others Experience or knowledge...sometimes though...its the way things are written...that can be read as BAD or NEGATIVE or FINAL WORD etc.....

here in Vegas we don't normally have freezing either...so with that said.....the boat may have come from out of state...you never know...northern region...

you very well could have a hole in the block / headgasket / intake leak / oring leak as Volvo stated or whatever......you already know this........

AND you want to drain the nasty stuff...easily... Might as well remove what you can AROUND the engine compartment so you can access the drain plug on the bottom...either way you need room to fix things and it will likely have to come out sooner or later so remove that stuff..eng box and the like

the engine sounds like it may have either hydro locked or overheated and siezed a piston ring to the cylinder wall......that is a couple reasons as to why it may have stopped running as the PO has stated.....or he's lying as to what really happened...either way ya gotta figure out what the deal is.....

this is what I would do

Pull each spark plug, one at a time, note how each plug looks.....carbon....light carbon....absolutely clean! BINGO!!! water getting in here and blasting the spark plug clean.........
or wet with an oil milkshake...either way thats is a bad cylinder....or has water instrusion

.....that would quickly give you an idea as to WHICH cylinder/s are having issues....

this would not necessarily constitute a Junk Block as some have said.......
they either havelots of money ...to burn on a 1000 dollar short block......or are not scientifically minded and care little for cause.....or have little patience or little wanting...to understand WHY the motor has died....as a new block could get jacked up in 2 minutes without proper identification of the CULPRIT....

I have personally seen... a NEW MOTOR lock up and ruin the crankshaft 3 minutes after someone DIDN"T figure out the problem was the original oil pump was TOAST.....
====================================
if there is no issues with the plugs....
----if engine can crank over (remove the coil wire)
do a compression check on the bad cylinder and another cylinder to compare to
(or all cylinders if you see no problem with the plugs)
if by some miracle the compression is fairly even all the way around

... something has to come apart....and get fixed....

pull the valve covers...you may see a crack in there or milky stuff originating from some particular area on the head...if so clean that area and look for a crack

next.....
yank the intake manifold....check gasket for a masive blow out area...signs of leak
remove heads....and look for cracks or have that part magnafluxed....
valve seats crack / in valve cover area on top of head can crack.....between cyliners on overheated engine can crack.....on flat part of head

you will be able to see a massive hole if there are any on the cylinder walls
or somewhere in the intake valley............

CHEERS and please let us know what you find!

Re: Milkshake In My 5.0 And Cant Get It Out.

Why does nobody suspect a bad exhaust manifold ? I had this happen to me, and got water in the crankcase (about 2 quarts). I drained it quickly, fogged the cylinders, replaced the manifolds, then went through 2-3 changes of cheap 5w-30 oil at idle to get the rest of the water out. That was 3 years and 150 hours ago- boat runs like a champ.

Once you elimininate the other obvious sources, then I agree that you should do at least a top-end tear down.

Re: Milkshake In My 5.0 And Cant Get It Out.

John has a point......

Maybye it is a simple fix such as the exhaust manifold...and parts can be had at Iboats.........

Re: Milkshake In My 5.0 And Cant Get It Out.

That is what I am looking for. I don't want to c hange the engine and have the same thing happen to the new one. I have started removing the engine tonight. Should have it on the stand tomorrow. The engine is not seized up so should be an easy tear down. I have access to everything I need to look for cracks in the heads and block at work. I found a reman 5.7 locally for 1100 so if it comes to replacing the engine, I'm all set...

Re: Milkshake In My 5.0 And Cant Get It Out.

Before you tear it down or do anything, pressure test the cooling system and do a cylinder leak down test

Just make sure that $1100 reman is a marine engine not automotive! 'nutcase

Ya Im good with that. There are allot of idiots on Craigslist who try and scam people into putting automotive engines and parts in their boats...

Re: Milkshake In My 5.0 And Cant Get It Out.

Is there a DIY post that explains how to pressurize the cooling system? I have tried searching with no results. I understand how one would go about it in a car but that's a closed system. What do you need to block off in order to pressurize the system???

Re: Milkshake In My 5.0 And Cant Get It Out.

Re: Milkshake In My 5.0 And Cant Get It Out.

the hoses that go to the manifolds from the thermostat housing need to be blocked off and thehose going back from the thermostat housing to the PS cooler and drive need to be blocked off. You can connect the two going to the manifolds together with pipe.

You can buy something like this from the hardware store and connect it to some pipe and connect it to one of the hoses.

You can also buy hose pinch off pliers but going to cost you if you don't already have them.
