Every morning, I let my 4runner warm up at least a few minutes, when I give it gas, water comes out of the exhaust, not drips, but a gush of water...what causes this? This only happens every morning, even in the summer here.....

 

like how much water is a gush?

 

It like having a mouth full of water and spitting it out, then its fine....

 

any coolant loss? mine drips in the morning but not a "gush"

 

I was losing coolant, had a leak in a hose, but I will monitor the coolant the next few days to see if I am losing coolant...if I am losing coolant, what could be the cause?

 

^head gasket

 

If it were a head gasket, wouldnt it heat up while driving? Could there be another possible factor? After the engine cools over night, would that allow water to seep through the headgasket?

 

my old truck used to do that too, its normal for certain exhaust systems, IIRC

 

Water is normal. Coolant is not. Find out if its indeed water or coolant.

Water comming out of a cold exhaust pipe is perfectly normal, its a sign that the catalytic converter is doing its job. I wouldnt worry about it

 

Its water, I put a cloth down where it comes out, also, there some black junk that comes out with it......like wet carbon

 

yea over time carbon can build up in a tailpipe, the water is just mixing with it I reckon.

 

It's mostly from condensation created when the extreme heat of the exhaust mixes with the cooler morning air.

 

Thanks for the replies, I wasnt looking forward to changing the HG at this time...
