    Default Water in Oil Pan

    Hi,

    Obviously I have a major problem. A little back ground. Back in 2006, my tranny cooler somehow developed a leak inside the radiator. Ruined my transmission. At the time I just used an external cooler and had my tranny rebuilt.

    Back at the end of 2008 I replaced the radiator and hooked up the lines for the oil and transmission. We put in a heavy duty radiator, a bit thicker than what was in it. From then to now I maybe put 2K miles on it.

    Now, the Suburban has about 130K. I have oil in my radiator, and water in my oil pan. I never noted a loss of power or any problems except overheating, loss of coolant to the oil pan. We never noticed anything unusual about the performance or exhaust.

    Today, I did a compression test, and the average was 160.

    I am hoping that the oil cooler in the radiator developed a leak as the tranny did before. I rented a kit from autozone to test the radiator. We disconnected the oil lines and filled the radiator. Hooked it up and did a pressure test. It appeared there was a very slow but steady drip. At the same time I noticed that the water pump appeared to have a slight leak, but it had not had one before.

    What would this be symptomatic of? Any help or suggestions would be appreciated.

    Also I might mention, when I took the plugs out, they had carbon on them. They were not really clean, they just looked used. They were not wet, but I did not run it before I took them out.
    The engine is a 5.7 Vortec.
    Oh, also, the dip stick is showing the pan way overfull.

    Again. I have not run the engine in a month, but the oil is thick and chocolately looking.

    to me it sounds like a blown head gasket, there are oil and coolant passages going to the cylinder head and it sounds like they are mixing some how

    When I asked this, I was asking if there were any year/model specific problems. Turns out there are. Like the intake gaskets are crap. But as a consolation, they make an upgraded gasket that I can pay who knows how much more than the normal ones. Not to mention the time I have to invest on it.

    Also the oil cooling side of the radiator was bad and transfering fluid as well. Pretty sweet for a radiator with only 2000ish miles on it. But atleast the shop I bought it from is replacing it with a new one.

    Then the water pump also was leaking. LOL... I guess the saying is right, bad things happen in threes.

    Now a question, do I need to remove the distributor to remove the intake? I have everything removed to take if off except for it. Its where I left off for the night.

    Also what do you recommend to flush the engine? I have so much sludge in it, it is ridiculous.

    Thanks.

    I need some help. Does anyone have a picture of a complete engine? I need to see how the ignition control module mounts to the upper intake?

    Thanks
