    I need a 4 door DC 4x4
    I have a 1996 2WD ext cab 5 speed 2RZ,


    Just rolled 233k on my way back from Florida last night, went to change my oil and noticed after i backed it off the ramp a fan type black mark right where my exhaust would be pointed. so i had my wife come start the truck and right at startup it covers my hand in black liquid like powder stuff. doesnt really smell like oil, doesnt smell like fuel.

    It never did this prior to my trip, i would have known since my tip is about 4" from the wall in my garage when i park.

    The oil was still amber when drained to a certain extent, no chunks, no shavings, no grit. Solid mpg (avg 26 at 75-80mph) When i had my wife rev it a little, maybe to 3k it covered my hand more so than on start up.

    The only thing that really come to mind are seals leaking oil into the combustion chamber (which seems odd if i had full oil) and on top of that it doesnt smoke at all, ever. Any help is greatly appreciated.

    im totally inexperienced with this but maybe ur catalytic converter is bad? as far as i know it's supposed to gather "pollutants" and it seems that in ur case it's not doing so... just a guess though.

    Sounds like carbon build up coming loose. It could be running a little rich or it might be from the long drive. How long has it been since you last changed your spark plugs?

    I'd give it a few days of "normal" driving and check again.

    I appreciate the quick replies,


    I will be doing some routine driving the next couple days to see if it goes away. Also i don't even have a cat. converter but i also have never had any of this before, so perhaps the drive did loosen up some nastiness

    the plugs were changed a few thousand miles ago

    Seeing as how it doesn't smell like anything at all really, im confident it will go away shortly, if not i know the muffler could also use a replacement, maybe its all nasty in there considering its the original

    Twenty Min of around town driving and no more nasty soot like exhaust stuff. Guess it was the no cat and 13 hour drive
