Antifreeze in Exhaust???

[chris clark]

A few weeks ago, I jacked up my car to change out rear tires/wheels. When I picked up the car, a couple of ounces of dark liquid came out of cat converter, or at least that's where it seemed to come from. I'm pretty sure it was antifreeze. I've noticed a smell of antifreeze, and the operating temperature is running maybe 8 or 10 degrees hotter than normal. Hard to tell for sure. I'm in Texas and the weather is getting hotter, I've only driven this car a couple of thousand miles and never paid a huge amount of attention to the temp gauge before, so it could be the warmer weather or my imagination. I had the coolant system pressure tested and it tested OK. Car still runs strong and seems to be OK in all other respects. It's a 99 996 with 68k miles and no previous motor work. So, is this my imagination or am I right to be worried???

Hmm, I would be slightly concerned. As you might have guessed, random stuff isn't supposed to ooze out of the exhaust system. The best thing I can recommend to you right now is to check your coolant level and record it. Then keep checking it over a few weeks and see if you're slowly losing coolant. If you are, then that's not good. If you are not losing coolant, then that might be just some type of condensation in the exhaust system and/or engine.

What were the jack points you used? If you jacked it up by the engine, you may have ruptured the motor mounts as they are oil filled and right next to the cats.

Yah the motor mounts are oil filled and I have a feeling you are right on how he jacked up the car. Easy fix though.

Stand back from the car looking at the rear exhaust pipes and see if it looks like the exhaust tips aren't both the same level. If not then good possibility its a motor mount. You'll know if you get a thumping from the engine slamming around getting on it.
