Bad Engine Noise

[moosey]

I have a 03' Turbo with tip and it has under 40k miles. While I was driving i got a strange metal can ratting noise comingfrom the engine. I do not no where it was coming from. This noise happens randomly at idle and almost everytime when accelerating up to 3000rpm. The next day I noticed a ddecent size leak of fluid that kinda had a smell like coolant, but looked more watered down yellowish brown. Checked all fluids and everything was fine. I was thinking maybe it could be a catalytic converter or something to do with one of the pulleys or even a water pump. Any help would be great.

at that low RPM, the noise could come from a loose weld in the exhaust or tip or even like you said the cat. got a picture of the fluid? check around your tranny to see if anything is leaking.

water pump?

I do hope your engine isn't suffering the same thing mine had last year: http://www.renntech.org/forums/index.php?showtopic=22070

Might be worth a careful check before it's too late.
