    ok, can someone point out where the main areas for a water leakage, without any visible signs? I filled up my radiator last week and it was about 10 inches low yesterday. I just had the water pump replace several months ago and can't see anywhere that it is dripping. suggestions and what signs to look for?

    Check the oil for water/antifreeze
    Any white smoke in the exhaust?

    radiator, hoses, frost plug, head gasket cracked head, cracked block.
    look for white smoke in the exhaust, this means your burning coolant, ie: blown head gasket, cracked head or block /forums/images/graemlins/crazy.gif

    getting some smoke on the first crank, seems to be a little blueish/white. I know some might be the valve seals. I'll double check it tomorrow.

    If your shure you aren't losing any water through a leak then like stated above I would be watching for white smoke. Another thing is are you adding antifreeze when you refill the rad? Antifreeze has a wonderfull habit of wiping the bearings clean of oil if you indeed have coolant in the oil. I would get strait water in there ASAP if you see milky looking oil on the dipstick.

    /forums/images/graemlins/thinking.gif, checked the oil and hadn't noticed it being milky so I'm assuming it's not going there. thanks for all the suggestions, I'll see what's going on hopefully after I get the grass cut tomorrow.
