View Full Version : There is water coming out of my car exhaust - is this a problem?

If I hold my hand over the end of the exhaust pipe I get a coating of water vapour on the palm of my hand.

I'm wondering if this is a sign of the head gasket wearing out, although I have seen plenty of cars with water dripping from the exhausts while sat in traffic before now.

What do you reckon? Worrying about nothing here?

hot exhaust hits cool air outside, water condenses out of exhaust...

Thats your car spitting at you. It wants to fight.

Teach it a lesson by pissing in the gas tank.

Absolutely nothing - the combustion of hydrocarbon fuels in oxygen produces water vapour :p

Yeah - thought so, but got a bit panicky.

Water vapour is fine. It's black smoke when starting from cold that's a problem.

If you're worried about the head gasket, go out in the morning before you start the car up and whip off the oil cap. Take a look at what's clinging to the inside of the cap- if it's just black and oily, you're fine.

If it's got creamy gunk, you've got problems.

Car exhaust isn't a euphemism, is it?

That's right, and if creamy gunk is coming out, it's a sign of past misuse.

Yes, if only because I know I'm automatically out of my depth with cars and leave it to the experts. Anything more complex than changing an alternator belt is a no-no.
