Hearing a noise at idle...
The same thing happens to my car, it seems to be a IX timing belt problem. Here is the link to a few people with the same problem: https://www.evolutionm.net/forums/sh...ght=belt+noise
I still have my noise but I will try some of the ideas to see if it works. I have already replaced my belts and pulleys and the noise came back after 300 miles.

It is an idler pulley, mine makes that noise and a friends evo makes the same exact noise too. He took it to the dealership to get it replaced but they didnt have the part. Mine has done it since day 1 about a year ago...no probs yet..

Sounds good. I'll see if i can set up an appointment this week to see if they can replace it. From the sound of your response, it doesn't sound like something I should worry about too much. Thanks everyone for your help.
Im still standing by my word. I had a simular sound but when we pulled my head off it was a lifter in my case but. But i dont dout all the other opinons either. Plus shipping from germany will be expensive HAHAHAHA!
What this sounds like is a roller or ball bearing with one bad roller. When the bad roller or ball has pressure on it, it makes noise. Then the bad roller has to work its way around until it is in the spotlight again. Hence the chug chug.
If you carefully check around the accessory belt with an engine stethoscope I suspect you will quickly find the source. I say carefully because if you are not careful the belt will ****** the probe and your hand with it. Doing this is dangerous.
Another way of checking is to just pull the accessory belt and spin each accessory and the idler by hand.
If that all checks out then I'd suggest the problem lies under the timing cover. This doesn't sound like a valve problem to me.
