Is it making a squealing noise. The pulley looks backwards. I had the same problem with mine where the belt started wearing and it was going towards the engine and squealing and the problem was I put the pulley on backwards. You will probably have to buy a new one if this is the problem because the pulley is hitting the block and now damaged. I switched mine with my old one and fixed the problem once it was put on right.

i don't think that idler pulley is backwards, its just not sitting right or something, or the belt is too narrow as its not an oem mitsu belt.

That's bizarre. That idler pulley does look like it's on backward, but I didn't think that was even possible without it being obvious.

EDIT:

Now that I look at it closer, it almost doesn't even look like the correct idler pulley; the lip looks wrong (besides being on the wrong side).

Look at it again. The lip of the idler pulley should be towards the rear and it isn't. Trust me I put mine on wrong and it looked just like this and it caused the same problem. The person that did a timing belt change before me did the same thing so I just put it on the way they did and then I looked at my old motor that had it right and noticed that it was wrong. That is where I would start.

You are correct I'm sorry I meant to say the tensioner pulley the one that is on the left side with the tensioner looks backwards. That is the one that I had backwards on my car also. Sorry I wasn't thinking straight on which pulley. The tensioner pulley looks backwards.

Well once again I am just giving you ideas of what might be wrong. I'm not there and I didn't do the work on it so it might be correct but I'm just giving you what happened to me and giving you a place to start. When the timing belt and everything were changed did you change all the pulleys also because maybe on isn't straight anymore or got tweaked a little. Once again just giving ideas out there to check.

ok update...so we did the timing again...and still it chews on the engine side of the belt...idk what to check...the new oem belt still sits abit weird on the idler pulley and it rubs of the metal behind what the idler pulley sits on..either that or the crankshaft plate..but if i had that on backwards..my car wouldn't run right..so idk what to do :/

I don't see how the timing belt could be what's hitting the dampner, I'd guess that wear is from the timing cover, specially since it looks like the belt is walking into the block not away from it..

I can't see the tensioner pulley well enough to tell what's going on there but this is symptomatic of the tensioner arm pivot being worn and not holding the pulley square with the belt which causes it to track one way or the other.

steve yeah the dampner rubbed against the timing cover, my only concern it the way the belt sits on the idler pulley and walking towards the block....but i have a new tensioner arm from extreme psi on the way. great people

Did you check the current one and the engine mount for wear?
The post for the pivot is part of the front mount and if ones bad the other is likely too. Don't forget to grease the two, it's not marked in the book but based on what I've seen it should be.

Did you eliminate the balance shafts and forget to put the sprocket back on the crank as a spacer? Really cant determine much from the pics.

And someone correct me if im wrong but isnt there a washer that goes between the idle pulley " arm" and the block? Maybe you forgot it and it is making the pulley offset toward the block. Hmmmm, maybe the washer is on the outside?

no i didn't I'm just guessing its messed up based on your posts and also the first time someone did the timing, they messed it up and the belt came off the cam gear ..luckily it didn't bend any valve...the tensioner pulley wasn't rotating n hitting the tensioner arm. so I'm guessing thats where it might have messed up. also could you tell me more about the front mount bracket that the idler pulley sits on? thats where the belt is rubbing IMO.thanks

i don't think this is anything relevant to balance shafts.i still have them in there and I'm guessing the crank trigger plate is on the right way as i heard if its on the wrong way the marks won't line up and the car won't run, my car runs good honestly i was at 20psi on my evo 16g before i decided to fix this timing issue n be safe.

Do you have the balancer shaft pulley and tin piece on there?

yes sir.

heres another shot of the tensioner pulley

i know this is a few years old, but i was refrencing it cause my fluidamper rubs the timing cover and i have to cut down the ring or else my fluidamper will look like the OP. which it never seemed like he found his issue.


just for shits. im gonna say theres a long bolt in the oil pan in the wrong spot chewing up his timing belt.
