about 3 degrees C today / 40 F

Test drove a 2.8 quattrofor about 20minutes. Temperatureat about halfway mark.All guages normal.

So it was thoroughly warmed up, parked it for about 15-20min while looking at car, then restarted, and a bit of greyish smoke from tailpipe.

Now this set off alarm bells - "why is there moisture in exhaust if car was thoroughly warmed up??" so I checked oil level, oil cap, Coolant level condition - all Normal. No milky oil, no sludgy coolant.

So am i just being paranoid? Is this normal post-romp condensation?or... Could it be a sign of headgasket trouble?

danke jungen!

 

If the oil wasn't milky and if the coolant looked normal I wouldn't be too worried. A really good way to check is have a compression test done on the car. That will tell you if the HG is messed up. If the car idled nice and the engine was strong I wouldn't worry too much.

 

At that temp most likely normal condensation. I've seen that even in the summer. To confirm if its the head gasket try listening for sputtering and subtle RPM jumps at idle or at open throttle. Check if the smoke is excessive and becomes more greyish white. Or simply smell it, burnt coolant has an unmistakable odor. You can also try compression testing.

Hmm...kinda reminds me of when we deliberately blew a head gasket on a HV, so much freakin smoke came outa that thing, it could've been used as a tactical smoke screen lol

 

good advice! The idle was absolutely fine, and engine was smooth and powerful.

**** i shoulda bought it yesterday than *droools*

 

not a problem the oil cap can have a gray milky substance and that's down to water or condensation in the engine and that burns off on a good run but nothing to worry about it quite normal, now the yellow mayonnaise stuff is different that meanshead gasket but I think we know the difference by now

 

Some parts stores sell a test kit. It contains test strips that can detect exhaust gasses in the coolant. Its a quick way to check. Head gaskets arent very common on audis thou.

 

Yeah I think you are good and just worried. The head gaskets don't really go unless the car has been killed

 

Put a glass jar in the freezer and then put it over the exhaust pipe. when you have some condensation, put the jar back in the freezer. If the liquid freezes it is water. If it doesn't freeze, it has antifreeze in it.

 

I too have noticed exhaust when I normally wouldn't expect to see any, but everything looks normal still - coolant, oil, and great compression.. I've blown HG's in the past and as Trey said, the volume is tremendous.... nothing like what I'm seeing on my 2.8

Methyl-Hydrate in the tank can usually get rid of excess moisture in your gas, which is typically the No.1 culprit of steamy exh.
