Is it normal, that when i rev the TL that liquid comes out of the back of the exhaust? I recently watched a video of someones else's TL and when they revved their engine liquid came out of the back as well. So is this normal?

 

It's just moisture, all cars do it when you rev an engine when the exhaust is cold.

 

and dont follow his example of revving it when the engine's cold.

 

The car was warm though, with the temperature gauge needle right in the middle.

 

Your TL is a ULEV (ultra low emission vehicle), so its exhaust is putting out (primarily) CO2 and water. Water coming out of the exhaust pipes is normal.

I echo the wise comments above about not revving engines in neutral--I'm amazed every time I see videos of guys doing this to their poor engines. Revving a cold engine is hard on it because startup is the time of greatest engine wear as the oil is not yet to temperature and fully circulated to lubricate most efficiently. Second, revving an engine that is not under load (not driving in gear) is hard on the rod bearings, and piston pins, and even rings and cylinder walls.

 

Thanks! i was a little freaked out at first when i saw the splatter marks. I also didn't know that about revving it while it's in neutral. Thanks for the info!

 

I think you're being overly cautious. Just running an engine is tough on all those parts, too.
