    alright, so i might have committed a sin with regards to my truck... when driving back from London, Ohio, i ran through a few large puddles, and i figured no biggie, ive driven in the rain.... although not a large problem at the time..... one of the puddles was hiding a large pothole.... so i hit the pothole, and the truck started knocking and wouldnt start for a while, so i let it cool and dry off, as tons of water was thrown about....
    after drying and cooling i start it up... about 3 miles later i notice that it is overheating... so i pull over and the radiator starts spewing coolant all over.... crap i think... once it is empty and dry, i fill it with another load of coolant and let it cool, throw two quarts of oil... it was low...and start it up again... with trouble it starts, then starts overheating again... I determined that no coolant was being pushed into the engine. I work for the red cross and had about 15,000 worth of equipment in my truck and had to get back, so i let it completely cool and zero out, load it up with coolant and oil, and drive slowly back home... a loud knocking sound as if the camshaft was busted was made the entire trip along route three home.... luckily i make it home, but not after spewing oil smoke out and being roastingly hot, the temp gague was twitching from zero to overheat, along with the noise...
    here is my question, is the truck busted? did i break a piston? I have heard a clang clang, and am probably a moron for driving it home, but I had no other way to get home and i was stuck in bumfuck ohio.....Would buying another engine work? or should i just scrap the truck and buy a suburban? i was thinking mid 90s.... any thoughts?

    It sounds like you injested some water when you were driving over the large puddles. You could have internal engine damage, pull the pan and inspecting it would be your best bet.

    Are you actually losing oil and coolant? Does your oil look like a chocolate milk? If it does, do an oil change on it, only if you are not losing oil. You might have to does this a couple of times to get all the water out of the oil, if this is your problem... Good luck! /forums/images/graemlins/thumb.gif

    Sounds like you hydo-locked it and broke something. Pulling the pan should give you a better idea...but from your description I think the motor is done. A new motor would certainly be cheaper than a new truck...

    I wouldn't be surprised to find you had a cracked cylinder allowing exhaust gases and stuff into the coolant and overpressurizing the rad.

    Agreed. Sounds like you got some water in there. A new motor is cheap when compared to buying a new truck.

    Didnt know it was that easy to injest water. /forums/images/graemlins/dunno.gif

    Wonder if he had an open element or something. Takes a lot of water to kill a SBC.

    100 cc's at just the right moment would be all it would take. A lot of vehicles have a cold air intake behind the grill...

    Or a loose air cleaner box /forums/images/graemlins/whistling.gif
    I was lucky as soon as I hit the water it died so I took all the spark plugs out and cranked until all the water and it wasn't 100CC got out. Cleaned the spark plugs put them back and fired it up and drove out.
