DF140 Water in Oil

[WEDOCQ]

Boat60,
That was some good investigative work! Now you have me nervous. I bought a new engine holder, and gasket. Any chance you can post a pic to show exactly what you are talking about as far as being slightly different? Mine is a 2004, and I bought the Engine Holder and gasket set from this site.
Thanks a Million!
Shawn

Its a bit hard to show in a photo especially now I have it back together but if you know the part number that you ordered I may be able to help.
If you ordered the engine holder with either part number 51110-90840 or 51110-90841 then you need a gasket with no. 51211-90J21.
If you ordered the engine holder part no. 51110-90822 then you need the gasket 51211-90J10.
Its a bit hard to see in the parts diagram on this site, but if you look at where the water jacket runs around the exhaust port look closely at where the round circle end of that water jacket is.On the gasket 51211-90J21 the outside edge has an extended hump that covers the hole that allowed the water to bleed across to the sump.
Hope this all makes sense.
Good luck!!!!!

Anodes

Check your internal engine anodes

check oil cooler

Looks like this site is back up again. Engorena, you need to check your oil cooler. Suzuki has indicated o rings can leak and cause oil/water contamination.

That was one of the first things that I did. Put new orings and even pressure tested it. My latest findings was extremely high water pressue. I too blieve that regardless of the pressure, water should not seep into the oil pan. However, when I removed the powerhead and holder, there was severe gouging of the surface around the exhaust port collector area. According to the machine shop spe******t, this was done by water hitting the very hot aluminum. I have never been able to get data on water pressure for this engine, but it was running about 25 psi at 4800 rpm. I removed the water pressure relief valve which was dirty. Cleaned it and made sure it work. Now I have not been able to put the boat in the water, but I have a water tank I run it in there without the prop. I ran it for 45 minutes, never got hot, but I did notice two things. At 4000 rpm, the water pressue was 12 psi and the other thing was that plenty of water was coming out of the exhaust port next to the pee jet. This has never happened before. In the past, it was almost dry exhaust coming out. I suspect that the damage done to the holder, which I was repaired at the machine shop, was due to the high water pressure. I think! Well, I shut it down and let it cool off, checked the oil and it did not have water. I know it wasn't under load, but it was the best I could do for now. I did speak with supposedly the premier Suzuki mechanic in south Texas. He said that I must put sealant on the threads of all bolts that hold the holder down and the power head down to the holder. I put sealer on all of them except for the long thinner bolt that holds the holder down on the oil pan before you put the power head on the holder. So, if I have to pull the engine off again, I will remove the head, have it checked for cracks which I have never done because it has never run hot and I will put sealer on all bolts and that little one I missed. We'll see!

next to pee jet?

I believe that is supposed to be plugged. We are talking about the port side spot (?) next to pee hole, should have rubber plug.

Also, I think the little psv (relief valve) is set for 13#.

need to plug next to pee hole

Engorena, look at the pioc of the oil pan (on this parts site) it has a plug, part #4. it should not be open.

Good morning! I checked the part number on item #4 in the oil pan IPB. It is called an "Exhaust Pipe" I have seen other 140's and it is open. I feel very optimistic, but we have had a lot of high winds down here and I just haven't been able to run it for an hour under load. Also, thank you for the pressure relief info. It was totally cruddy and had not been removed in years. If I have to tear this thing down again, I will replace this valve. If I get a break in the wind this Sunday, I might just take it to the ship channel to get a final verdict. Thank you for everything and I will keep you posted.

[briscoe]

Ship channel?

You fish the Galveston Bay complex? I found out my boat had small leak on the head gasket, under warranty..... Sweet.

Well guys! I'm back. Got busy and just got a chance to go fishing. Ran 4500 for 15 minutes to my first fishing hole. Checked oil, no water. Ran another 15 minutes, not water. Ran back to dock at 5,000 rpm for 15 minutes, little water in oil. I guess I will be tearing it down again. Water pressure never went over 15 psi. Never got hot, never smoked, never missed. I changed o-rings in oil cooler earlier and out of desperation, I am thinking of ordering a new cooler. I just can't see how 15 psi water pressure would overwhelm 70 psi oil pressure? I could see losing oil threw the cooling system. Any new developments out there on this nagging problem? I have been a mechanic most of my life and know all the sympthoms of a cracked head or blown head gasket. In an open cooling system like this, water would not leak down into a cylinder, thru the rings, and into the oil pan. Looking for advice!

[briscoe]

feel your pain

I understand your frustration. I would not mess with the cooler. It has to be a head gasket. I had some of your issues. Having an extended warranty, I took it to the dealer and they pulled it apart and found a head gasket leak on the top cylinder. Running it hard made mine heat up and leak water in oil. Staying around 4500 rpms, mine was ok but still put a little water in the oil. WOT was really asking for it, when I gave up and took it in. Sorry bro, where do you live? Sounds like our weather here fishing Galveston Bay.

Thank you for responding. I have the same feeling, I will pull it apart next week and have the head checked for a crack also. I missed alot of fishing down here in the Laguna Madre (South Texas) because of this problem. I will get back to you when I am done! Have a Happy New Year!

Okay, got some interesting developments. I pulled the powerhead off and put it on the table. Looked inside intake ports and there is rust everywhere! All four intake ports around the intake valves and stems. The intake valves have light rust on the combustion chamber side. The cylinder walls are beginning to get light rust! Can water be leaking into the fuel system from the fuel cooling manifold that feeds the injector manifold? There is no breaches in the head gasket and there is no sign of moisture in the exhaust side. When water is seeping into the exhaust ports, it will basically clean the port and these ports are black. The piston crowns are super clean and have this reddish tinge to them. I'm taking the head in tomorrow to have it redone. Before they do that, it needs to be checked for cracks and then a new valve job. My compression was at 180 hot, so I will have to think about rings, real hard. I don't think they have 25 hours! Wish me luck!

Just got a call from the machine shop, no cracks, head is perfectly flat. The only thing that was very clear, was that the water jackets had quite a bit of trash. The underside of the lower cylinder water jacket was completely plugged up with shale looking stuff. I am contemplating breaking down the block and I may as well. If I haven't found anything and put it back together, it's not going to get fixed.

[briscoe]

Not good. Dealer that pulled my power head and broke apart the head said I had a gasket leak on the top piston. Nothing real bad. The extended warranty people wanted the power head shipped to Florida. After a month they told me my head did have a crack and they were replacing with new one and then rebuild.
The scale on the water jacket is crazy, you had aluminum anodes? I did get to see my engine holder and it was clean. The head was already packed and I didn't see it though they said it was all clean. Sorry to hear about your not finding head issue. You pulled the power head and looked at the oil sump and peered under to the inside of the engine holder, right? That is the only other place I know you could get milky oil, through corrosion.
