Water in my Engine!

For what little i know, sounds like cracked head or head gasket.

I painted the manifolds this summer with new gaskets. I torqued them down to spec. I don't think that would be the case.

Pull your spark plugs and see if you have any water in any of the cylinders. If not, it's not the exhaust manifolds. It could be an intake manifold though. Is yours aluminum? They corrode easier.

If there was rust there and you did not make absolutly positive they were square and flat,you are the culprit.Sometimes you can see the rust lines, mostly not.
A motor of this age will have an uneven srface and be almost impossible to seal, a remove and replace is in order. A good machine shop will surface the riser and the mating surface to like new for a few bucks.
Malibu dont think its the intake, read the above post as to the "I removed the manifolds to paint them" as a prelude to the water/oil issue.............

Chris, WHAT IS YOUR PROBLEM? Can't you deliver a post without cutting someone down or name calling? I'm going to explain how an intake can cause this problem. Pay attention and read very carefully. You might just learn something! There is a water passage that connects the two heads together that goes through the front of the intake. I have seen these corrode through near the flange that bolts to the head. This can happen on the underside of the manifold as well. Now, what is below the intake. That would be the valley of the block where there are drain holes for oil to get back to the pan. Now, I wasn't trying to tell this guy that the intake was his problem. I just mentioned it as a possibility. That's it!

If you had something to suggest that could be this man's problem, why didn't you offer it here? Oh, let me guess, you couldn't spell it. Too many of your posts read just like this one. You hammer people for their comments but you have little to offer in return that someone can actually use. 4023 posts of you calling members names and belittling them and using vulgar language has landed you the "Grand Poopah" status. You must be proud.

   I've got water in the oil AGAIN myself.
R&Red the busted exhaust manifolds @ 239 hrs, ran on a fake-a-lake for a hour-clean, ran 5hrs.retorqued the exh.manifolds, changed oil-clean. Changed it @ 250-clean , changed it @ 275 perfect. At 279 I put a timing light on it, heard a knock pulled the dip stick the oil pan was FULL of an oil/water emulsion. So-WTF.The last time I ran the boat the water was glass 25-40 mph for an hour or more and it ran very,very well. Drained it,pulled the plugs put in 4qts.of dextron III & did a compression test-all 8 145-150 psi.I pulled the intake and found the oil emulsion under the intake at the water crossover at the front and back of the block.I inspected the intake gaskets but they were damaged removing the intake.I changed the intake gaskets, 5 qts 40 wt rotella and filter. CRAP !!!

Ive seen the intake manifold crack right under the thermostat housing and will indeed fill the block

Thats about right but I might change the order of the list depending on the recent history of the engine/ storage/overheats/etc

Funny thing about pulling the intake the 2
"pockets" in the head between the intake runners where oil collects (351w) ( an oz or 2 ) that oil looked fresh from the can ?
Are you still looking for a ski pylon ?

Reidp was in my drive way when I installed the new exhaust manifolds & risers. I did the compression test as I flushed the engine. The engine Knocked very little at idle , moved the throttle up to 1500 or so (at the dock) the knock went away , back down to idle it came back & I shut it off .- Found the oil pan full of water. Still need to restart it.
I think "the list of possibilities " would be good in the frequetly asked questions.

Should I consider doing a complete rebuild? There are 1500 hours on the engine, and it seems like it is time. I dont want to spend more money searching for the problem.

I only hammer jack ass' like you, Start a Malibu site and offer your worthless banter there.

Yes Aluminum corrodes it also will oxidize instanly too, but you have to have special equipement to detect that too. Now that your scratching your head, what is rust? oxidized iron maybe? what's the time frame for that to start.

You offer nothing of value but tail chasing circles and wild goose escapaids and where do those go no where. Now if that aluminum intake as been on the boat for thirty years then it might corrode through but I really doubt it's been on the boat that long and pigs have a better chance of flying than your theroy's or help.

How do I test them? Unfortunately I dont have access to many tools because I am at college. My friend has a lot of tools about an hour away, I guess that is my best solution. Do I need an air compressor?


Also, why would it be the block? The boat is stored down south and garaged.

How far down south? My first boat came from below atl and had the exact crack that Eric mentioned above(thermo housing). It had a telltale oil leak at the front of the intake.

The exhaust manifolds seem fairly new (0896 are the digits on them).

The boat has been in South Texas or South Louisiana for the past year and a half.
