This morning I tightened up my header bolts and went over the whole engine. A clamp on my orp was loose, so I tightened it. Then I started up the engine for the first time today. I looked underneath to see if I had any exhaust leaks. Where the Y clamps to the headers (both sides), there was water dripping/spraying out. Not alot, but enough to form tiny puddles. It had no coolant smell, and was clear. After a few minutes it stopped. My radiator is full. I let it cool off for a few hours, started it back up, and no water. What could it be, condensation in the block or something?

 

That is usually normal and one of the signs of a good running engine

 

This isn't anything to be alarmed about. It's not uncommon, particularly when it's cold out. My car sat for a while over the holidays and did the same thing when I fired it up on Saturday. It's just some condensation.

Thanks, that's kinda what I thought since I didn't smell coolant.

 

I've been told by people much smarter than myself that an internal combustion engine that burns fossil fuel produces approximately one gallon of water out the tail pipe for every gallon of fuel consumed. this is probably more noticable in colder climates where condensation of water vapors in the exhaust systems occur more frequently. I always make sure that there is a tiny hole on my mufflers at the rear and bottom backside, about 1/8" dia, to keep water from collecting and rotting them out. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
on the other hand if you are seeing water dripping from joints in your exhaust system, this means you have a leak and probably need to seal it if there is a posslbilty it will affect your O2 sensors.

This is why when you store the car you should do more than just start it up and run for little bit.You should drive it to make sure all the moisture is out of the system.

you only realy need to worry about leaks affecting the o2 if it is right by it the factory put holes in the exhaust to drain the water
