do you use your parking brake?

Sometimes when you leave your parking brake on and then start to move, the rear pads stick to the disc and they pop when they let go.

Did you say its coming from the rear?

 

He said he gets it even when it is stationary. My guess: thermal expansion is causing the noise.

 

I was waitnig for someone to gring this up. I have the same sounds too. It is most likely metal expansion. I wouldn't worry about it. Car runs fine. What I do is I use that to gauge when I can start driving. Like my car saying" okay I am ready to go". Since a good number of people have this and not just me, then it should be okay.

 

My car makes the same noise a couple of minutes after it starts. It seems to be louder when it is cold outside...I wouldn't worry about it. You could always mention it to the dealer at your next service.

 

I just asked the tech at my dealership about it, and he said it's the sound of mitsubishi voiding your warranty due to neglect.

 

Wow, I haven't read my owner's manual in a long time, but I believe it's in there or maybe I read it in a car mag. The stock exhaust on the EVO has a flange, that stays partially closed until the exhaust gasees have warmed up enough to heat up the cat so that emissions are controlled faster, the noise you hear is completely normal and happens every day with my car when the correct temperature is reached and the flange opens to normal operating position. The only reason I probably hear it more than others, is I'm always standing outside my car smoking a cigarette while it's warming up. This flange also opens up more at completely wide-open throttle (this I believe I also read in a car mag).

I can't remember where I read it, but knowing how I am, if I thought it was something wrong it would be at the dealer as soon as they opened, so I must of read it somewhere that had some authority on the car.

 

Guys, please don't use 60 weight oil in your engines. You should use the lowest viscosity you can get away with for the weather you are using your car in. Heavy oils are used to mask oil leaks and other problems in very high mileage and worn out engines. From a cold start you need the oil to get where it's going as quickly as possible or you will slowly kill your engine every time you start it cold. 10w-40 is specified in Europe for some reason; here in the US it's 10w-30 unless it's going to be below -10 F more often than not until your next oil change, then use 5w-30. You can get away with using as high as 20w-40 if you won’t be driving in temps below freezing, but please keep in mind, the thicker the oil is, the harder it is to push through the engine. Higher viscosity oils cause a slight loss of power and lower fuel mileage without adding a significant amount of protection to moving parts inside your engine.

 

THANK YOU SATORI! Thank you. finally someone else who understands that thicker is not always better.

The Xw-40 spec in a lot of Euro cars can be attributed to a lot of things. Higher sustained driving speeds is a possibility, but CAFE restrictions here in the States is another. By forcing auto manus to increase fuel efficiency, a byproduct is lower weight oils.

I like to compare the Euro spec to the US spec in choosing the "appropriate" weight. It can tell you how the manufacturer would like the car lubed if not controlled by gov't regulations.

ferb!
