Exhaust spitting water
My Dad took me out in his Nissan Almera (aged but in showroom condition), always serviced, and low miles,
But when dropping us off today, I noticed excessive liquid being expelled from the exhaust.
The liquid didn't smell of petrol/oil/antifreeze...and the car I presume was upto temperature, after a stop/start 5 mile drive vs the amount of fluid ejected?
Temp gauge reads normal, just passed an MOT a couple of months ago, radiator level normal.
So why is it spitting out/leaking this water out the exhaust? A theory of mine is that the backbox is split externally? And retaining moisture, that is then turning into condensation, that is being blown out? But internally the exhaust is good?? Would that make sense?
Other than that, I'd suggest premature HG fail/cracked head, but motor is fine, no excess noise, no loss of power, no loss of liquid in radiator.
Bizarre! I know HG fail to piston, I took the rad cap off my Capri, to get a facefull of (thankfully cold water!); and the engine pumped out water quicker than I could add it!
But this car seems to be losing a lot of water, when it is running in hot weather, for a reasonable time for it to be at operating temperature.?

I think you answered your own question.
It probably needs a good old Italian tune up.......“I may not agree with you, but I will defend to the death your right to make an a** of yourself.”

when you burn a gallon of petrol you get a gallon of water, this starts out as steam when it comes out of the engine but if the exhaust isn't hot then it condenses to liquid in the exhaust and can appear as liquid at the tail pipe.
As long as no water is being lost from the rad then don't worry about it0 -
Oh my god. I can't believe you are so stupid. You're the kind of person who shouldn't be allowed on the road. I can't believe you don't know the answer to this and yet you have a driving licence.
Of course it's a split headgasket. That's the only possible explanation for water coming out of the exhaust. Where else does a car have water in it other than in the cooling system. Your dads car MUST have a leak between the water jacket and the exhaust side of the head. The coolant water is literally running out of the engine and down the exhaust.
Or perhaps, just perhaps, water is the byproduct of clean combustion of hydrocarbons, and you should have paid a smidge more attention in Chemistry lessons.

not everyone is familiar with cars, people come here to post questions and learn. stop being a !!!!! about it.0 -

Erm...not sure this is right! Air has a certain moisture content which is the passed through the engine and expelled through the exhaust. Now if its a short run and the exhaust does heat up, it condenses up again and spits out as dropplets of water.
OP-check to see if this happens after a short journey or also after a long run. If its latter then you have a coolant leak (head gasket).0 -

Don't be so condescending! This is also possibly wrong given that you do not know if its re-condensation after burn or split gasket.
As said in previous post a long journey will determine this. I.e 30 miles, not 5.0 -

No, Vaio is quite correct. It has nothing to do with the moisture content of the air:Erm...not sure this is right! Air has a certain moisture content which is the passed through the engine and expelled through the exhaust. Now if its a short run and the exhaust does heat up, it condenses up again and spits out as dropplets of water.
CxHx+O2 (combustion)=> CO2 (Evil carbon dioxide) + H2O (water) with an exothermic release of energy that is harnessed to drive the car forwards.
The water normally vaporises in the heat of exhaust - the "smoke" you see from car exhausts on cold days is in fact almost all steam, not pollutin smoke. With a cold exhaust, you can re-condense the steam to water, and it drips out of the tail pipe. A car used for short runs may go through this process many times, and the back box can be literally full of water that is then expelled through the force of gas when the engine is running. This can produce quite an alarming amount of water...
But a head gasket failure bad enough to have water running from the exhaust tip? The water from the exhaust wouldn't be your first symptom: the overheating engine and total lack of water in the coolant system would be.
To expand on my first post, I was merely "getting one back" on ratboy who was calling otehr people in need of genuine help stupid for not knowing how their clutch works.0 -
