Newbie questions: RPM revving and mysterious fluid leak
Hello, I'm a new WRX owner. I wanted to say hello to the other forum members and ask a couple of quick questions.
I bought an 02 5 speed wagon that is in pretty good shape given it has 180,000+ miles on it. It uses some oil (still figuring out how much), but otherwise runs and drives fine. This is a project car for my boys and I to work on and have some fun with. The first question I have is about the engine revving between gears. No matter how I drive it seems to "hang" onto the rpms when I shift between gears. This is my first manual car with a turbo. I've heard of some of this, I'm just not sure what is considered normal. My last manual car was a 84 Camaro with a 350 swap. Second question: I have a mysterious fluid leak upon startup. The fluid is clear and seems to come from somewhere right above the turbo. It drips for just a couple of seconds and stops. The liquid evaporates pretty quickly. It seems like its water, maybe some sort of condensation. It does not smell like antifreeze, it smells a bit like oil (but its clear). I thought it might be the fuel line issue, but the last owner replaced those and it seems to come from a spot were there are no fuel lines. Plus, it doesn't smell like gas at all. Any thoughts on what it could be? Note: my car does not have the engine shield underneath, if that makes any difference.

One more note: As far as I can tell, my car is bone stock with no tune whatsoever.

There's no way his 02 has an electronic rev hang programmed in.
You are letting off the gas a second too late, it will go away once you time your foot action better. |

Perhaps the throttle cable is a tad tight. You say this leak drips...from where?

Leak is condensation from AC
(Designed like that) Drain hose is on R side of engine compartment |

Thanks for the replies. I'll continue to try get timing down and see how it goes.
The a/c condensation makes a lot of since, however it is weird to me that it is only when the car starts. I also haven't run the a/c a whole lot as it is cold right now. I did test it a couple times. The exact location is between the turbo inlet and the engine. I've traced it about halfway up the block. It's been a minute since I checked or I could give more. |

The revs hanging for a moment may actually be normal. My 03 kind of felt like that after driving a civic for ages. As for the fluid isn't there a power steering line that runs back there somewhere? I've heard stories of engine bay fires from power steering leaking on the exhaust.

I can assure you a 2002 has no emission related "rev hang".
As mentioned first thing to check is your throttle cable for kinks, twists, binds or tightness. If the cable itself is OK check that there is slack in the cable (and cruise cable) when the throttle is closed - the cable should not be tight. As far as your fluid that would be something you need to try and pinpoint a source. If it is just water and not coolant or oil it most likely would be condensate leaking from the exhaust side of the turbo. For it to be exhaust condensate you would have to have an exhaust leak. It is possible you have a cold leak and as soon as the exhaust starts warming up the leak closes. BTW: It takes a while for the A/C system to build enough condensate to start dripping - that would not happen on a cold start. |

for the liquid could be condensation from the exhaust where a small leak is, particularly when cold
