what's up everyone! Wanted to see if anyone knows what's going on with my car. I have a 98 avant 2.8, whenever i start the car the engine makes a loud turbine like noise coming from the passenger side. It only happens when the engine is cold and last for abouta minute or so, kinda sounds like a grinder. Anyone know what's going on? please help me out, thanks!

 

sounds to me like the secondary air pump which pretty much would sound like a tubrine

 

I was reading up on it, yeah man I think you are right. thanks!
