I've noticed a considerable amount of water leakage from my exhaust system. If the truck is on an down hill slant or level ground, I'm getting leakage in the pipe at a spot before the muffler. If the truck is on an up hill slant, the water comes at the end of the muffler (bottom section). While I realize that condensation does build up in the engine/exhaust system, I'm used to seeing it come out at the end of the tailpipe. The amount of water varies from a few drops to a small drink glass worth. I'm concerned that if water is escaping from these areas so is exhaust air, which I'd only want coming out the end of the tail pipes. Should I be concerned about this?

 

This is normal and I know the search function in this conference does not work right now but there have been numerous topics on this. I have a 2001 right now and I had a 98 Supercab and both truck did it. I think it is suppose to prolong the life of the system by letting the water out of the little holes. I don't like what it does to my cement driveway. The rust spot in the picture is a combined effort of both the SCrew and the 98 SCab.

 

There's one way to prevent this problem. Just drive 20 miles on the freeway before you go home.

 

You should see the puddles (yes, two of them) under my F350 w/V10 in the mornings. It puts out so much water that it runs down the driveway into the street- about 15 feet.

 

One of the by-products of combustion is H2O...This is how us old timers could tell if the engine was running efficently, look for the water out the tail pipe...

 

Been thinking. If you're getting that much water in the exhaust, then that means it's taking a really long time to heat up the system. Are you guys sitting there in the mornings with the engine idling for a long period of time?

 

Define "long".

Our trucks (wife does the same thing) usually idle for about 5 minutes before we take off. May be slightly longer- but not much. I've noticed that the amount of water depends a lot on the humidity.

 

Just want to add that most of the replies talk about water out of the end of the exhaust when the engine is on. I should have been a little clearer, I was talking about water coming out of the bottom of the muffler and parts of the exhaust pipe system after I've driven the truck.

 

5 minutes is a long time to idle the engine. That's why there's so much water dripping out the muffler in the driveway. These days, all the experts say to put a gentle load on the engine asap, or at least as soon as the engine settles down. In other words, start driving gently asap. The engine will warm up faster and during the winter, it will start warming up the cabin much sooner.

 

Wonder if we can get the experts to come down and drive the truck around in these frigid temps until everything's warmed up.

Seriously, I don't think 5 minutes is going to hurt anything. And it sure beats freezing the ol buns off. Plus, I don't really care if there's water dripping from the exhaust. Just trying to reassure mbrim that it's "normal". However, based on his last post, I don't think we're talking about the same issue. He said:
Of course it depends on how long the truck has been driven, but I don't think that there should be water (a lot anyway) coming out when everything is up to operating temps. Now, if he's talking about after he shuts the truck off, then there will naturally be some condensation as the air in the pipes/muffler/cats cools off. How much will be dependent upon the ambient humidity. Just be sure to check the fluids and make sure there aren't any coolant leaks.

 

Sorry about the weather, but you should be driving this truck 5 seconds after starting it and it does warm up faster with a load on it, better gas mileage as well...

You will get a ton of water in the exhaust this way, and when the condensation collects...you can see the water being spit out of the exhaust while it idles...puddles will collect at a red light..you can take a glass and fill it just from idling...this is all normal..she floods and that is normal!!!

If you have a blown head gasket you would know about it by now...it would have overheated...water lost out exhaust=no water in engine=overheat condition...

Sorry about being to the point...
