I bought a motor from another party and put it in. When I started it, i noticed on the drivers side exhaust, what I think is water dripping. I have started this motor and let it run for 15 minutes 3 different times and the last two times I added bars leak to see if it will stop. No luck....Each time I start it, it drips for a couple minutes then it will stop until I let it sit and start it back up again. I took a valve cover off and there was quite a bit of moisture in there. Another thing that puzzles me is that I have a little bit of antifreeze in the system and when it drips out the exhaust, it doesn't show any signs of antifreeze in it. What do you all think is the problem???????

It's right there but I can't get it off my tounge dangit..

Pull the oil and see if it is colored white or dis colored in any way first... If not then It may be fuel coming out the exhaust. We have that happen quite a bit on fresh motors, but not for long, maybe 5 seconds...

Yes the oil is milky looking, in the valve cover anyway.

i had that happen when running alcohol for the first time, the engine heats and because the alky is so cool of a charge we ended up with condensation when we first started the motor every time but only until the engine got warm.
we never had anything in the oil and it was fine.

Hopefully there is nothing wrong. I had a person tell me that if you took one of the radiator hoses off and held it up and either turned the motor over or started it, he couldn't remember which one it was, and the water bubbled, the there was a problem. His only problem was that he was told this by somebody else and he couldn't remember what I really had to do. Has anybody ever heard of this, to tell if there is a problem with a cracked block or some other problem?

What is the outside air temp? I think it is condensation. Look at some street cars they drip out the pipes all the time. It could be collecting in the pipes then when you start it it pushes it out. Are you losing water out of the rad?

DONT TAKE THE HOSES OFF AND START THE MOTOR...you have to take the cap off. with the motor runing, if the water is bubbling you have a cracked head or cracked block.

Even on methanol, water or condensation will not drip out of the headers. The water is coming from a crack somewhere, nore than likely. You will always have water in the oil with meth but that is normal and evaps out once the motor is up to temp. Just the nature of it. Dripping water is a problem though and it sounds like it's leaking when the motor is cold and stops when heat makes everything expand sealing up the crack.

every alky motor i've had will drip out the exhaust right when you start it. i've got a 2 into 1 pipe and i'll get about a teaspoon or less on the floor every time if it's cold. the inside of the valve covers dripping with water is normal. let the engine run a couple of minutes and shut it off without reving it and pull the carb, i'll bet you have water setting in the intake. you said you have a little anti freeze in the coolant so, i know this sounds crude but, stick your finger in the stuff on the floor and taste it. if its antifreeze it'll taste sweet. if it's alky condensation it'll have little or no taste, a little bitter maybe.

Best way to check for a blown head gasket or other combustion area leak. Cold motor, take the water pump belt off. Take the thermostat housing off and refill the cavity with water shake the car just to make sure all the air is out of the heads. Start the motor. Which ever side is blown will blow bubbles out of it. Must take the fan belt off to do this as it will cause a false indication.
