I noticed it while i was checking for oil leaks after changing my oil is it something i need to get fixed? Water was coming from where these pipes are jointed.

 

it is absolutely normal. when you first start a gas engine the primary emission is water! and with a big v-8 there is a ton of water! that is why most of todays exhaust systems are made of stainless steel because the were always rusting from the inside out.

now you know why short trips are so bad! because you don't give the engine enough time to burn off the water from the oil, exhaust system, etc.

so the moral of the story is never drive your truck less than 30min. and idling doesn't count!

 

Water is a byproduct of the cumbustion process for gasoline. No worries.

 

For the price it would cost me to run my truck 30 mins or more every time i drive, id rather pay for new pipes every 6 or 7 or more years. I just replaced my 4 year old full boar muffler with a Y pipe and it was only slightly rusted inside. The insides of my pipes looked fine too-- a few flakes of rust, and 90% of my driving is 5 miles or less in town.

 

well green you have been lucky that you drive a truck that has a well made exhaust system! it is all stainless steel. if you were driving a honda for instance you would be on your 2nd or 3rd exhaust!!

the other problem is that some of the water gets into your oil so you really need to heat it up at least once a week and make sure the pcv valve and system stay functioning properly because it is the pcv system that removes the water vapor from the oil.

 

a leak wont change the back pressure or anything to make my truck run wierd will it?

 

a small leak no a big leak slightly yes. your cats provide the majority of the back pressure. it will all depend on where the leak is.

 

All fuels have a certain amount of water in them. All fuel pumps have water seperator filters, as do all diesel vehicles. A good way to check the quality of your gasoline, is how much water/moisture is coming from your exhaust. Run a higher quality gas, and you will get better mileage and less water/moisture from your exhaust sytem.

I prefer to spend 5-7 cents more for a gallon of gas, to get a better quality product. Plus, I get better mileage that way.

Just my input...

good input ranchero. however this thread is about water being the byproduct of the gasoline combustion process and the amout of water produced has nothing to do with water "in" the gas.

in addtion most "water" in your fuel system is due to condensation and is caused by consistantly running around with less than a 1/4 tank.

 

I thought that water was the byproduct of the gases flowing through the catalyst in the catalytic converter?

 

nope it is a byproduct of gasoline combustion in a primarily cold engine.

thats why if you walk arond and look at a few mufflers you will see a tiny hole at the lowest point which is for water drainage.
