    Default Ahhhh water in my motor

    Ok so i was out saturday running me 1981 miller with a 512 ford, i made a couple passes and came back in i went back out ran one time and heard a ticking noise, so i shut it off and towed it back, got home pulled the valve covers off and yes they where all out of adjustment, but here come the bigger problem, there is also water in the oil, im stuck and dont know where to start.

    ok first the smartarse answer -oh never mind that one ...now couple things...drain the oil ,valves are next. see if you have an exhaust open too long or an intake that doesnt open at all, you might have a hydraulic lockup about to happen get the valves right first -hope its not worse you didnt give a whole lot of info ,this is a start and the rest goes to peeps better than me.dont forget to put oil in when you restart the thing.and please adjust the valves with the intake open adjust the exhaust and exhaust open adjust the intake.does it have a little water or gallons-if its a bunch you have a problem

    Start with pulling the manifold and heads. Then check the piston to deck height and reading the gaskets as you tear down. from the sounds of it you may have lost the intake gasket and wet down a cylinder. the ticking could be a cam going south or lifting the head a pinch. Is the oil out of the crankcase a milk shake? Or are you just seeing it in the valve covers? M

    its not alot of water the oil just has a slight milky look to it, basically i was running about 6500rpm the boat got a little hot just under 200, and stating making a ticking noise so i shut it down and towed it back.

    Any sign of water in the oil needs a check. FWIW just under 200 is where I prefer to run. I don't think that was the problem but more what gasket let loose to allow it wind out in the pan. For a qwik check and before a tear down, fire it on the trailer and see if the ticking went away. But the water in the oil is still an issue. So I would just tear down "SLOWLY" and check the gaskets. Start with the intake and if by luck you fine it replace and try again, before the water test run a compression check. M

    This is a little confusing even for me Ol Guy. Start with pulling the manifold and heads. Then we will look at the oil in the pan?

    Are you suggesting he tear down the engine for something that could very well be nothing more than condensation in the rocker area.
    Any idea the number of people that panic when they see that?
    jmracing, first things first. find out if there is water in the pan. If not, you just need to get you oil temp up. Also, what are you running for valve cover breathers?

    first, check the oil in the pan, or remove the oil filter and a look the the oil there. does it look like oil, or creamed coffee.

    Read before you bash! He already stated the oil in the pan shows water! M

    Start with the exhaust, do you run water to the headers and have a long duration cam? Very common for water to be sucked back into the heads at low rpm and will color the oil. Try running the boat with dry exhaust. [Also if a camlobe goes flat it too will cause water to be sucked into the engine.] If that doesn't cure it check the front cover, [assuming it's a jetboat] most jetboats use the stock Ford aluminum timing cover with a waterpump blockoff plate. It is common for the cover to leak due to age, corrosion, too much pressure from the jet pump or a combination of the above. If you find no leakage in the cover then look to the intake manifold for leakage, again too much pump pressure will squeeze water past the gaskets as a jetpump produces alot more pressure than the engine was designed to handle. If no evidence of leakage is found there then its time to drop the pan and pressurize the cooling system and look for the raindrops. To add: even if it is a V-drive you still can have too much cooling system pressure at speed from the thru hull/plate water pick ups.

    Really. Where is that exactly ol guy. I see in the first post he talks about removing the valve covers. In the 3rd, you have him removing the heads. In the opening sentence.

    No he didn't. Read before you answer.

    I'm not suggesting you do anything to make you uncomfortable - but before you go taking that engine apart, are you sure the water in the oil isn't just condensation? If not, I'd take a look at the intake gaskets before I went to jerking heads...

    Is this the boats first time out for the season?

    Were the valves out of adjustment to start with?
    If not, somethings going away for sure?
    Roller or flat tappet?

    It does sound like possible intake gasket with the water deal, just from your info, but valves out of adjustment could mean more damage from the water?

    It's a lot easier to diagnose when I see water in my deal. Generally I'm missing half a cylinder and the boat is sinking, with water pouring out of the giant hole in the pan...

    The key word here is valveS, as in plural valves, or all the valves... If all, or most are in fact loose, and not just deflated hyd lifters, I fear the watered down oil MAY have wiped out the cam..... Without more engine info it's really hard to make these wild guesses, but you know the guys in the dyno section, myself included, love to make wild speculative guesses.... As mentioned, do some more detailed investigation before you go tearing things apart. The first place to look is inside the oil filter. Cut it open and look for crap between the folds of the filter media... If it has little sparkly things in it, you have found a good reason to start careful "forensic type" dis assembly...

    That's what it sounds like.
