MG TD TF 1500 - Condensation from tail pipe

It gets pretty humid here in the north central Piedmont of NC. Yet, when I crank my TD up in the mornings there's a considerable amount of condensation that gets blown out of the tail pipe. It doesn't equal anywhere near a tea spoon but it's still enough sooty moisture that has collected in the tail pipe and muffler to make notice.

Anyone else experience this with their TD?

I'm checking the radiator to see if the level stays the same to make sure I don't have a crack in the block. I haven't seen any water leaking anywhere else under the engine nor steam emanating from the tail pipe after driving several miles and getting the engine warmed up.

RC,
This is common in all vehicles,,,, It's only the "white smoke" that you have to be concerned with !

I'm used to my truck and motorcycle blowing moisture out through the tail pipes, and the TD as well, but of late it seemed to be more than normal. I just checked the radiator and the level is where it is supposed to be.

I've never heard of a creak in a block going into the exhaust. If you had a creak in the block wouldn't the water end up in the oil? And the oil would show cottage cheese looking chunks in it.

I've always been under the impression that the water in your exhaust is condensation; the exhaust system is hot when you turn off the car, as the air in the muffler cools the moisture collects and when you start the car the water gets blown out the tail pipe.

Once the cars exhaust get warm the moisture in the air gets vaporized only to show up when it has cooled down.
The only concern I can think of is the water causing internal rust in the muffler.

Gasoline + O2 + heat = H2O + CO2/CO. The primary function of an internal combustion is to make water - the secondary function is to make your car go. :-)

I had the top of a piston come off and the head was cracked and a lot of steam went through the exhaust. No water and mixed. I kept adding water and drove the vehicle to a repair shop.

I checked my oil in the TD yesterday and it was pristine. It was good when I changed it last month as well. No milk.

I think I'm going to install the stainless steel muffler and tail pipe.

I dont know what the thoughts here are concerning stainless steel exhaust components are however I am aware that on some vehicles they can have a very negative effect on a vehicles performance.

Stainless steel does not dissipate heat and hot spots can develop in the muffler and tail pipe which create turbulent gas flow. A mate had a stainless system fitted to his Fiat in the 70s and until he removed it the car would not run smoothly once it reached operating temperature, Dyno tuning tests were used to diagnose the problem.

G,
I can't be sure what an exhaust system on a Fiat is like, but a stainless system on a TD is basically straight through, , not much in there to cause turbulence,, IMHO, I think there might be more to the story about the Fiat not running smoothly when it reached operating temp,,,
All new vehicles are stainless exhausts,,,
with the way most T Types are driven now, I would highly recommend a stainless exhaust,, a common steel exhaust would rust out in just a few years,,,

Aircraft have been running stainless for 70 years...some pretty exotic systems operating at very extreme temperatures in really harsh environments...sometimes very LONG runs..NO issues with temperature dissipation...and this is with long runs in close proximity to aluminum and magnesium components. I think the MG's are fine running the hot gasses from our little XPAG/XPEG''s out the back. Regards, tom

I put a new Falcon stainless system on my TF. The fit was perfect with the exception, I had to re-arch the pipe slightly in a more upward angle where it goes under the axle tube to make it level under the bumper. PJ

I was under the impression that for every gallon of fuel a car burns it produces a gallon of water out the exhaust.

R. C. Flowers, how much alcohol does North Carolina put in the gas you use?. I recently spent a weekend in Iowa where the premium gas does not have alcohol in it. I filled up in Iowa with the premium gas and returned to Minnesota where 10% alcohol is added to our gas. For the last week no water on the garage floor until I filled up with Minnesota gas. I suspect you may have corn blowing out your tail pipe. Just a point of interest, during the cold season here in Minnesota we have what is called black ice on the roads. Didn't have black ice before the corn was added to our gas.

Steve Wincze, I must be the exception as I'm running a standard exhaust supplied by Moss in 1977 and 37 years later it's as good as new.
John Quilter (TD8986)

John,
I guess you are the exception!! I find it hard to believe that a non stainless system would last that long!! Just a curiosity question,,, how many miles on the system????

Steve Wincze, The mileage since 1977 is 22,000 approximately.
John Quilter (TD8986)

That explains it !!!!!!!!!!!!!!
