I replaced my Valve cover the other day and obviously had the cam cover off to do it and noticed a quarter inch wide groove that looks like was evenly dug into the timing belt on the inside just before the inside edge. It's cut maybe an 1/8" deep into the timing belt. What would cause this and is the timing belt compromised to the point that it will need replacement?? It would really suck if it did because I can't imagine it would be cheap to fix. Here's a pic. Thoughts??

On the oil pan there are 2 bolts that are shorter than the rest. My bet is that they were mixed up and the longer ones used in their place. They would be located near the oil pump gear.

You should not drive the car. Replace the belt now. You should be able to remove the offending bolts easily from the bottom of the pan without pulling the whole thing off, but the damage is done.

A)The belt is toast

B)It is now very prone to failure, no matter how you drive.

Your choice, a $75 belt and an afternoon of work OR up to 16 bent valves, broke pistons, etc etc which will cost you WAY more.

OK OK I get the picture. That's why I was asking you guys. I'll look up an FAQ about how to change the timing belt on this thing, because I've never done one and I don't want to drop 500+ bucks on taking it to a shop to have it done. You guys do make it sound like it's not too big a deal. What timing belt would you guys recommend I buy then?

Stock replacment from the dealer. Yes, the dealer as in a Mitsu belt.


They aren't that hard. Your first time will take a LONG time. Some people make it a point to say they can do a timing belt in 45 seconds. So far I have yet to see any sort of award for getting things done uber fast. Take your time, clean things up, and double check everything. Once you have done a few they will get easier.

Thanks for all the quick replies guys! Now I just need to order one and find an FAQ on what to do.

I'll buy that kit. Looks like a good one for sure. Just ordered the belt from Mitsu. 38 bucks. The tensioner belt is 36 but 4 days minimum out. Not sure if I need to replace the tensioner belt however seeing as the motor "apparently" has less than 1000 on the rebuild.

Well, considering this failure is due to a mechanical issue, the belt is the only thing that really needs to be replaced. Assuming everything else under there was replaced when it should have been.

Sorry if I missed it but do you have any idea when the t-belt was done last? If it were me I would buy a new water pump, all new tensioners and seals. No way I'd go through all that labor and just slap a belt on.

From my understanding this engine is supposed to be a pretty fresh rebuid. This is not an uncommon screw up. So as long as nothing else under the cover is damaged, only the t-belt needs to be replaced.

If you were priced a timing belt for $38, your dealer is either generous, high or selling non-OE parts. They pay more than that for it from Mitsubishi.

The person who also told him it was just done didn't put the right bolts in the right places. Sometimes the 100 mile rebuild isn't as described.

That's what the guy told me, straight from the mitsubishi parts department. I sure hope it's OE Mitsubishi, or I'll buy that Greddy one I found for 52 bucks. I'm seeing the genuine Mitsu belts online going for around 65 bucks, so we'll see. I gotta say, after reading that VFAQ, I'm not really looking forward to this....

Just make sure you set the motor at "top dead center" so all the marks line up BEFORE you lock the tensioner down and remove the old belt. Then just make sure every mark is spot on when you release the tensioner pin after the new belt is on and you will be good.

Thanks for the advice man. Pray to the Gods of every religion that I don't FUBAR this engine....Looks like it'll be down at least a week, maybe more since I need to buy that timing belt kit and wait for it. All I can do is tear it down and get it ready to remove the belt in the meantime.

You have to recheck the tension of the belt. I think it is highly inadvisable to skip that step.

True. Perhaps Galactica should check receipts to see what was purchased new. My buddy had his car completely rebuilt with new parts, and they messed up that one bolt. No sense in tossing all those perfectly good parts because one bolt was placed in the wrong spot.
