So I finally got my 8 back today after a long time of body work & an engine replacement due to overheating caused by an accident.

The dealer replaced everything and told me that my 8 was ready to go and the only thing I should keep an eye on was that there was a tiny bit of antifreeze residue still left in my exhaust that couldn't be 100% cleaned up by the dealer. The smell is def. antifreeze when the car idles and burns it off.

The dealer told me I would just have to drive it for a little while and let the rest of the antifreeze that was in the exhaust burn out. They told me that they cleaned all that they could, but there was a tiny bit that still needed burnt (leading to the white smoke).

My question... I am going to drive my new engine under break-in for a while, but are there any ways I can successfully burn this residue off otherwise. I was told to just give it time and it will burn off and everything will be set. All this true?

 

I would suspect so. That exhaust is damn hot. I burnt my leg on the tip and it left a permanent scar

 

Itll burn off, enjoy the smell

 

It will need more then a trip to the store and back. IT will need to warm up real good one time.

 

How did antifreeze end up in the exhaust in the first place? Still using the old exhaust that was used with the replaced engine?

 

how did coolant got into your exhaust in the first place ?

I see that you said you had an accident, but I mean how ?

 

That does sound fishy that there is coolant in the exhaust. First of all, how did it get there, secondly, if it was there, why didn't they just dry it out with compressed air, and third

WTF???

 

Sorry for the delay. When I was in the accident, my radiator was punctured cuasing coolant to leak out everywhere. After looking at the engine, Mazda diagnosed that it needed replaced b/c of overheating (side walls and/or seals were absolutely busted). The rep at the Mazda dealer told me that when the auto body shop tried to start the car the last time (when they noticed it didnt work), the compression of turning it over was firing coolant that was in the engine, out through the exhaust. So instead of burned fuel being emissed, they said it was flushing the coolant out b/c it was in the engine. Make sense to anyone?

I'm still going through the break0in which abosolutely SUCKS, but I'm trying to schedule a decently long trip so I can lock up a lot of miles and have the luxury or switching around gears frequently and ranging the engine. Once that long trip happens, I'm sure the intense heat and length will hopefully do the trick.
