I was just wondering if holes in a muffler would affect the power in a 85 300TD wagon.

#1. Recently my car seems to have been less powerful and I found out there is a 3rd hole in the muffler after patching

#2. The loudness of the 3rd hole discovered seems to be coincidentally timed with the power loss.

Could there be any relation?

I didn't think so, but hey, I'm still learning about these machines..

Thanks

All your power could be running out that hole...

Serious?

I found the hole just near the joint to the front of the silencer, on top I believe.

By "power in a ...wagon" do you mean 12V, 120V from an inverter, Solar, wind, persuasion, positive thinking? What kind of power are you toting around in your TD?


So by 'have been' it has power back? Note that these OM617 powered W123s are dogs. So if you ride your bike down hill for a few days, the W123 might seem slow in comparison.

Might I suggest turd polishing? (laugh with me please). Perhaps just cut the muffler out and add a piece of straight pipe. I did this with 2 of my benzos and it worked great. No noticeable increase in noise, as compared to before the leaky exhaust. It was quieter after the repair, so mission accomplished and zero dollars spent using left over piece of straight pipe. Granted not everyone has a Mig Welder or access to one, so this project offers some challenges.



If you read this by itself out of context, this is HILARIOUS !


Read below.



I nearly spit out my coffee !


Interesting digressions in earlier posts.

If I may address the OP directly and start with my disappointment that no one suggested the piece of crap muffler could be dropping parts internally and maybe its restricted inside? I mean the stupid thing is going into failure, why not fail inside?

Cut the muffler out, replace with piece of straight pipe and come back and tell us how much nicer it is to hear the turbo and the nice exhaust note.

As for power loss, when was the last time fuel filters were replaced? Just because it was done 1000 miles ago, doesnt mean there isnt a problem. How good are the fuel hoses? Any leaks? Is the airfilter clean? How about the line from the intake to the alda? Is the banjo clean? Read about OM617 power loss and address those obvious items as well.

Are your brakes dragging? Any tires low on pressure? Did you have the A/C or Defrost on?

Note to all reading this: The Turbo acts as the first muffler. So having a straight tube exhaust is still muffled.

Playing scrabble? There is plenty of power to be had out of a 617.

That would cause the power to back up into the engine making more available to the rear wheels...

LOL,,,,, no,,,,he is kidding...
only in a situation where you had tuned exhausts would a hole mean less power... otherwise it would mean more power due to less restrictions... but increases the chance of CO getting into the car... so they need to be fixed for many reasons..

There is NO CO in diesel car. That is you can never commit suicide with a diesel fuel car due to CO poisoning. LOL

A hole, depending on how big, should have more power as there is less restriction.

http://wiki.answers.com/Q/Can_you_get_carbon_monoxide_poisoning_from_diesel_semi_trucks
""It is completely possible to get carbon monoxide poisoning from a diesel engine in a road tractor. Contributing factors such as weather, temperature, and engine condition can greatly affect the chance of carbon monoxide poisoning. A good example of this is that a driver in a truck with an exhaust problem when it is cold and raining is at greater risk than the same person in the same truck on a sunny day. The reason for this is the barometric pressure holds the carbon monoxide closer to the ground and allows it to enter the truck.""



http://www.hdot.org/en/learning/myth-fact/diesel1
""A properly tuned diesel engine produces exhaust that contains about 1% carbon monoxide because the fuel is burned much more efficiently, especially when the engine is idling. That is why truck drivers can leave their trucks on all night without fear and why diesel-powered vehicles and equipment are favored in mining or underground situations.

Conclusion
Carbon monoxide is deadly in very small concentrations-as little as 4/10 of one percent (0.4%) or 4,000 parts in 1,000,000.
Although diesel engines do produce less carbon monoxide in their exhaust than do gasoline engines, they are equally as deadly as we will see in Part 2 of this series.""

Taking a chance on lives... based on the assumption that an engine is working perfectly ... which was the assumption you proffered... is not being prudent. They make a small amount normally....but can make more with any part of the system worn or out of adjustment...

Leathermang: You omitted the first paragraph in your quote, by design or mistake?

http://wiki.answers.com/Q/Can_you_get_carbon_monoxide_poisoning_from_diesel_semi_trucks

"This is possible, but unlikely. Diesel engines detonate fuel using pressure and temperature, rather than with an artificial spark. This process operates with excessive oxygen, ensuring a much more complete combustion than what is typical in a gasoline engine. Typically, diesel exhaust contains some carbon monoxide, but the amounts are very minimal and not fatal for an otherwise healthy person."

In a nutshell, a hole in the muffler will not kill the OP, definitely not in a moving car.

You said Diesels produce NO CO....That is UNTRUE.
You clearly do not understand the physics of red blood cells and their relative affinity for attaching CO instead of O2 and the consequences.... Long term... hours .... of exposure to even small amounts of CO can produce serious consequences health wise.. and you ignore the " otherwise healthy person" description... there are lots of older, sick, compromised immune system people around....
Did you only read ONE reference and then post ?
You are as off base on this as you are on AC issues.

When I added straight through mufflers on my turbo 5.0 mustang it lost considerable power. Lower back pressure meant lower power. I had to make adjustments to the fuel curve and wastegate to get power back. Ultimately I had more power but it took some serious adjusting so with a turbo I would say it is possible at the very least to lose power from an exhaust leak.
