    Default Water in the Oil!

    Aside from a head gasket, block/head damage or sinking the thing, how else would you get water in the oil?

    I have heard of mad wives/girlfriends using a garden hose!

    Seriously, does the engine have an oil cooler, that's another way, how about an intercooler if it's blown or turbo?

    How did the intake manifold gasket look when you pulled it?

    Thats a thought..... it does have an oil cooler?????? it does have an intercooler also, but no oil through it. I am not fond of the mercruiser oil cooler anyway, I will have to check that out.

    While I have you obnoxious... I am putting together a 454 mag efi and using the procharger m1sc. I have a new crate 454 mag (marine) engine. (spankin new on the crate) would you reccomend changing the head gaskets before running it with the Procharger (5 p.s.i)???

    If an intercooler has a leak, the water will drip into the cylinders (when it's shutoff), and get past the rings- much like an exhaust manifold leak. Both will get water in the oil.

    If there are no leaks, then it could be just condensation. The oil needs to get above 250 degrees to evaporate it- the Merc cooler usually will not let that happen.

    Yes I would put a set of Cometics on it now, sure a hell of alot easier as it sets then to blow one and have to do it later.

    It is a procharger, so the intercooler is remote mounted unlike those big babys in your avatar. Funny though... the procharger setup has you remove the t-stat and I know my oil temp has not been getting that high. I have over 100 hours on with the procharger and the oil was always clean until last trip out.

    Not for a long time....it runs a sea pump and usually that keeps the exhaust from backing up. Used to have a flattie with bassets, so I know what youre sayin

    maybe to much water pressure??? I had a flattie and put a new magnflo water pump on it and it had way to much pressure until I got it regulated it was blowing water right past the gaskets. Just a thouhgt good luck

    Default ***Warning****

    If there is that much water in the oil you need to pull it down and at least look at the bearings, AND if you run a wet sump oil pump you NEED to thourghly clean the oil pump, AND be sure to disassemble the relief valve area and clean it well. Any water that accumulates in the pump goes right to the bottom, exactly where the relief piston lives. These pistons WILL rust in place and give you lots of grief later. Like blowing oil filter o rings as soon as it starts again....Ask me how I know this..........MP

    Is there anything you could run through a motor if you did get water inside, I was told ATF would be good is that b.s.? Obviously you need to figure out how it got there first.

    I have been told that the exhaust manifolds can also cause this. Let us know what you find. My engine looks just like your pictures as of last Monday.
