Checking on my latest flaw / fix

Heavy Smoke coming out of exhaust upon hard acceleration.
http://www.acadiaforum.net/forum/index.php?topic=4793.

I noticed four puddles this morning, 2 under each muffler.
2 small at the tips, and larger under each muffler (talking about half a cup)

Then I remembered over 20 years ago, I worked at my uncles shop.
I remember thinking "why does he always punch a hole in the muffler after every install?"
Isn't it going to rot out? Maybe he'll get repeat biz for a new install?

So one day I asked....
" in short trips & stop/go driving, water accumulates in the system, the hole allows some to escape and it prevents premature rotting from the inside"

Sounded good at the time. Why didn't Walker do this?.... repeat business?

20 years later, I think he was ahead of his time! IMHO :woot:

Leaking muffler?

I haven't taken any pictures of this yet. Let's see if this is normal or not first.

I was hooking up my trailer yesterday and bent down and saw what looked like water dripping out of the mufflers.
There appears to be a dark spot near the center (bottom side) at the lowest point.

Is this a drain hole to let out condensation?
The vehicle was just started and had been running only a few minutes.
I don't remember anything in the owners manual about that. However, they don't say anything about the air conditioner leaking up to a quart or more of condensation either.

Has anyone else noticed this?

Re: Leaking muffler?

yup thats a drain hole to let out moisture from the muffler.
theres also one further up.

On cold days- you see the exhaust as steam- on warmer days-- the moisture condenses inside the cold metal--- so they add a weep hole.
once you drive around- the exhaust is hot enough to keep the moisture as steam and out the tailpipe it goes.

water-- is a natural byproduct of the combustion engine.

Mine "leaks" as well, only on the right side though.

Re: Leaking muffler?

the dual exhaust vehicles- should leak on the rt side only.. as its only 1 pipe coming from the engine-- that then in the rear- splits into 2 exhaust...
not a true dual exhaust....

Re: Leaking muffler?

Thanks for the pictures and info.
I'm going out west to a much dryer climate.
It will be interesting to see if in a dryer climate it (the condensation) might dry up over night and not leak at the first start up.

I'll report if it does dry up and doesn't leak out west.

Re: Leaking muffler?

once you drive the car for a while and the pipes heat up-- no moisture should remain.
dripping will occur on all startups. Im here in Los Angeles and I see dripping.
If you do very short drives.. like 1-2 miles one way then it may not be long enoug to heat up the pipes. and you may see more moisture....

ON a side note-- I think its acuras-- that Ive seen pull away from lights-- and literally see water pour out the exhaust....and im not talking about drips.
ill try to remember tommorrow and see if mine drips in the am

I frequently see Crown Vics do that. Water just pours out the exhaust.

Re: Leaking muffler?

water or exhaust?

id say if a little exhaust gets out the drain holes-- no problem.. it is a drain hole for water-- meaning it has access from the main pipe.

Odd, mine always drips on the left in the mornings, I've never noticed the right at all.

Re: Leaking muffler?

its one pipe from the engine- and splits into 2 right in the rear.
you should check and see if theres 2 mufflers with leaking holes or its just a pipe on the left
