Liquid dripping from exhaust

Ive been noticing quite a lot of something dripping from under my car as I pull into my garage and after a little while of my car sitting I checked under the car and there was little puddles under the back of the exhaust, and some on the exhaust it self. I put my finger in it and smelled it, didn't have any smell.Click image for larger version

That's just the new synthetic muffler fluid. The old non synthetic didn't do that.

I thought it was the residue from the rain water collected through the intake that helps cool down the engine. Usually you're supposed to see it come out of the tips, but occasionally it drips from the mufflers if your intake didn't push through enough rain water for a constant flow through. A break in the stream would cause it to get stuck in the mufflers and drip.

Lol. I still have those in my car. I was contemplating getting a pic with them in your exhaust but then thought naaah, he might kill me for touching the exhaust tips.

I never experienced this untilI got my new '14 Mustang, and thought "xx?%%%%!!" My own mechanic told me it is perfectly normal condensation. You'll find that after longer runs it isn't there when you look.

OP, I'm disappointed ya didn't taste it.....

+1 normal it is more common on short trips till it gets hot enough to evaporate from exhaust heat.

If it doesn't stain the driveway, it's just condensation (made worse from the ethanol in our fuel). But if it does stain the driveway, you need to be checking your oil, coolant, etc.

In this pic, my car was burning a qt of oil every 800 miles. Somehow the cats kept up - never smoked that I could see.

Since then Ford stepped up and dropped a new engine in.

Shows you why exhaust systems rust out. I have weep holes drilled in my new Flowmaster mufflers and a hole in each ex. pipe(in the lowest point in the pipe. You'd be amazed how much is in there. The more that comes out the better.

The reason for the puddles is because the car was started and because of the initial heat of the motor and the cold exhaust condensation was made and the car wasn't ran long enough for the exhaust to get hot and burn it all off. They all do it.

looks like you have an exhaust leak at the clamp on your axleback.

It is his exhaust. he meant to say muffler.





and your exaust will collect more water... ehem... synthetic muffler bearing lubricant.... if you do a lot of short distance driving. Generally, you gotta drive longer, let the car get warmed up, and for gods sake, bring those rpms up and have some fun. then it will evaporate and exit the right way, as steam out the tailpipe, instead of collecting in the muffler and draining from there.

Fun Tip: When you see it happen, go rev a few times around 5k or so, then go look at the splash on the ground behind your car.

I don't mean to bring back an older thread but for the past 3 weeks I have had some black oily fluid shoot out of my exhaust on starts. It's is mostly after it sits over night. There are not mufflers on the car anymore, just Magnaflow axle backs (pipe after cats stock H pipe and stock resonators). I added a JLT catch can sometime ago but some oil has still been getting through... So every morning and afternoon this is what ends up on the driveway:

Ideas? I just don't want to go to the dealership and sound like a goof. "Hi my car shoots oily mess out the back"... I feel an odd look coming... I do realize condensation could build up to a point but this has put black spots all over the driveway. About 5 or 6 patches now.

That's what I was thinking but it seems to be a more than I'm used to... Tailpipes are filthy after 200 miles as well. I think I will drill some drain holes in the bottom of the axle backs and see where that gets me.

I'm all stock besides catch can and axlebacks (found some Magnaflows for stupid cheap so I had to get them...)
Might get a tune in the coming months.
Will be checking oil in the morning after I get to work. I checked after I got home today and it seemed to be normal.

Figured out what it was...
Since I back in to the driveway the sprinkler system was spraying (damaged head) and getting into the exhaust. Our sprinkler system has some "organic goop" add in so maybe that is why it was a bit slimy spray. Adjusted the sprinkler timing and all good.

Wipe your finger around the exhaust tip if its oily then you have issues. But, I doubt it. If your finger comes out sooty your burning oil. If it comes out wet and gooey you know what to do.

Liquid dripping from exhaust

Sounds like I'm burning oil at the most though. The pipes get real dirty after a 2 days, end of the week you'd think they are powder coated black.
Thanks on the driveway, next one will be normal concrete. This tile stuff is slick.. Busted my end once so far out of 3 years, leave tire marks once a week.

Liquid

Now that everyone has had their fun.
It's water and water is a byproduct of combustion.
Some days will have more than others.
Also, if you look at your mufflers there will be a little hole on the bottom of them, that's to allow the water to drain.

On my stock mufflers there may be a hole but I don't run stock mufflers.
