Is this oil contamination in coolant?

  1. #1


    GM3800 , the radiator leaked so they used stop-leak. Didn't help and engine has likely been overheated.

    They tell me the stop leak product looked a bit greasy or oily. I dunno it doesn't really stink like oil, the oil dipstick only shows regular black motor oil. The lighter swirls in the diahreah if I pick some up with a finger without mixing it almost looks like diluted copper antisieze.

    Some fairly similar pictures online people say is oil contamination

    Under the thermostat on the engine almost looks like a milky blob

    NVM the fluid isn't illuminated for photo

    3.8s are great engines. Fucker is fine and it probably made it stronger when it overheated

    Rusty gunk is fairly normal in older engines, and so is build up of white goo and a slight smoking when opening the oil area as well. Not something to worry too much about.

    Heater hose connections at the heater core were fairly difficult to remove , tucked in tight under evaporator connections.

    Worst one was reinstalling lower radiator hose to radiator, tucked in tight and couldn't get the hold-open on spring clamp to release in tight quarters. Probably shoulda attached it before getting radiator 100 percent in place

    The clips for transmission lines also were good knuckle scrapers , never done those before.

    Chinese radiator seems like a POS there was aluminum chips under the dust caps and the hose connections had little to no barb on them, and the nut plates stripped out before getting snug used the old ones

    Is this what you have been working on for the last 2 months?

    Anyways, I don't think you have oil and coolant mixing. Usually looks more blobby than that.
    Just fill 'er up with supertech and try again.

    ↑ what someone with weak fingers would say.

    hoses, radiator or otherwise, are meant to be installed with just your THUMB AND INDEX FINGER.

    keep training until you acquire sufficient finger strength.
