Noise
Hello-

I've had this horrid noise since 83kish and I'm at 114k now a few garages have no idea. The noise seems slightly different now and lasting longer than what it sounded like for a while. It's lasting longer like 5-8 min till the car is really warmed up. I have a 2005 mitsubishi eclipse GTS

It sounds different now I don't know if it's due to the work that was done to it and it caused the problem to get worse not sure. It used to last seconds to maybe 2 min. I just had the tensioner and belt replaced, water pump, pulleys, AC belt, Idle pulley main serpentine belt, plugs, wires, distributor cap and rotor. Plus they changed my oil which I usually due myself. I usually use castrol synthetic with a K&N filter so I'm guessing the garage used some cheap stuff because I forgot to tell them what I used. Although what I used didn't really mater the noise was still there but it didn't sound as bad and last as long. I'm going to upload a video the video sucks but you can hear

If you want to hear the noise just go to youtube and type in 2005 mitsubishi eclipse GTS noise. I just posted it today.

If it does it without the belt on hen it's internal noise. When was the timing belt replaced last? 60 k is recommended miles.

Ya but the noise started 20k ago so it can be internal. Take the belt off and see if it persists if it does then it's internal like a cam, followers, etc. And the timing belt is different from the fan belt.

I had the timing belt replaced it was part of all the repairs. One garage took the main external belt off and it didn't make noise, the following day once the car was cooled down they put the belt back on and it made noise. The only thing is, is that it doesn't make the noise every day, and I told them this. I just wish they would have tested it longer. Some say lifters, some say tensioner although my tensioner was replaced, and some say my starter is going. Some say the top end isn't getting oil fast enough and to change my oil to try something thicker. Ive asked if that's the case should I replace my oil pump and they've said no for some reason. No garage has tested the car by having the timing belt off. It to me sounds like upper passenger side near timing belt area is the loudest. Garage said bottom end sounds mint.

If it doesn't make the noise with the external belt off then the problem is in the accessorie drive like the alternator/ac pump or pulleys/belt tensioner. I say this because you stated that when it was put back on it made the noise again. Call a garage and have them check the belt tension with a belt gauge it should be 110-154 ft. Lbs at the point in pic. That I am sending. This cold be a minor problem with the a/c compressor clutch as well. But not having it to see I cannot give anyother suggestions.

Oh really for some reason the garage told me if the belt is off and it doesnt make noise than nothing is wrong with the external parts, if the belts on and does make noise, than its internal. The garage was a little iffy anyways, so I took it to a new garage which is the garage that ended up doing my work. Are you suggesting it could be something to do with my timing belt area with this diagram?

No that is the external belt not timing belt and if they don't have enough tension thenit can cause some noise but I think it will come in correctly if check with a belt gauge. First garage had everything backwards. If the belt is off and not making noise then it's the stuff like alternator/and what isaid previously.
