    Angry Metallic Oil

    Allright, so just as the title says, took a look at the oil in my car, and saw little flakes of metal in it. Im going to talk to my mechanic today, and see what he says. Could mean a few things. One, forged bottom end, serious pistons (build for a 150 shot) and heads rebuilt with a cam. Or two, crate engine ls2. I'll know more after noon today.

    I'd build it for more than a 150 shot. Thats nothing. A stock motor should hold that no problem. I'd go with a stroker if you end up doing a forged bottom. Shouldn't cost much more, if any. And for the cost of a crate LS2, a 408 might be a better option.

    go with the 408, do it right the first time.

    and you can put 400 shot if you want

    could have something to do with that spun sparring issue you had.

    If you want to know for sure, change the oil ASAP, and get a UOA. Cheaper than a motor.

    I had a similar problem on an LSX engine but mine always had piston slap,turns out the metal in the oil was coming from the piston rings and cylinder walls, eventually it had so much blow by it smoked all the time, but he oil pressure was always good.

    UOA's are the only way to actually get an accurate answer. Hopefully your mechanic knows that.

    Do not buy a crate LS2. Waste of money, more engine can be had for same amount of money.

    Please go more in depth....
    How can any metal on the plug be something not to worry about?

    Don't know about you, but on every car I've changed the oil on, there was always a little, but if the oil is full of it and metallic, then thats a bad sign.

    To a point.

    A little fine dust is one thing, flakes are another.

    Well lets talk oil
    Firstly...it is a serious FUBAR to analyze oil with eyesight/color/smell. Get a UOA done and lets see what we have going on. http://www.blackstone-labs.com/gas_engines.html

    Secondly most wear metals are non ferrous. Simply put....they wont be attracted to a magnet. Pistons are aluminum etc.

    Thirdly there are lots of "shiny" components to a used oil soup that have nothing to do with engine parts wearing.

    So lets get a simple and cheap UOA and see what is happening so we can adjust.

    Nope, definitely millimeter size flakes on the dipstick, swimming in the oil.

    Ok, so I should have said Im starting with a 150 shot to familiarize myself with how the bottle changes driving characteristics. The build will depend on the damage, but forged is where I told my mechanic I wanted to go.

    I think thats more then likely the case. Before i broke it there was no metal in my oil. Now there is.

    for example a new engine or a rebuild... you're gong to have it no matter what... and you're still going to have this happen through out the life of your engine...

    First post i know. But I just bought a 99 z28 and me and my friend changed the oil and he said that there was some metal on the drain plug and got all serious about how i need an engine rebuild and i have a spun bearing!?

    I saw it and it really wasn't anything that would have set off my alarm but i guess he knows more about it than i do. Also he is a big 4 cylinder turbo fan so maybe he was just making me feel bad for getting an 8?

    all in all should i be considering a test as posted above to see if i have a spun bearing?

    Your friend is more than likely a tool.
    If you spun a bearing you would know it. If the engine runs fine/strong.... why the hell would you re-build it? Get a UOA on your next oil change maybe.
