Any Mitsubishi experts in house?
Hey All,
I have a 1991 Mitsu Galant 2.0 liter SOHC and it looks like the timing belt is probably broken. The car just quit on the wife about a mile from the house and I could tell a difference in cranking speed when I tried to restart it. I see no rotation when top belt cover is removed so seems to be my problem. I've done some internet searching and don't like what I'm hearing. Does anybody know if this...or most of this type engine is an interference type? It seems like my next move would be to pull the head and check for sure, but thought I would ask for any input here before I got out the "Metric Stuff"
It's says alot when a man has to turn to an antique tractor message board to look for these answers because he doesn't seem to "Rouse" any interest on a large Mitsu board he found. This board never seems to amaze me with the broad range of knowledge available from the members.
Thanks in advance!

Chris - I can't answer your question but if I was going to bet, I'd bet that it is an interference engine. Breaking a timing belt is never good news. Good luck!

If you can't fix it with a hammer, you've got an electrical problem.

Not familar with the Galant engine, but i do know that in 1991 many 4 cylinder engines were in the process of being redsigned to cure the problems of the pistons striking a valve left open. Ford reccomended changing the timing belt evey 30 ot 50k as a safety precaution against that.. A compression test once the belt is installed, but unless you can find someone with better knowledge I would suggest pulling the head for inspection. Most of the manufacturesr have instructions statign new head bolts should be used when a gasket is replaced. At the very least og to your local autozone, Oreilly's, etc and spend $20 for a service manual if you don't already have one.
If you are not part of the solution,
you are part of the problem!!!
you are part of the problem!!!

Hi Chris,
Did you hear any knocking when you rolled the engine over? If not, you might be OK. But...
Before installing a new timing belt, I'd pull the valve cover. Most engines have a bolt holding the pully on the camshaft. I would roll the cam over with a ratchet and watch the valve action making sure that all the valves move up and down freely. If they do, then I'd go for the new timing belt.
Good Luck,
Brian

Most interference engines lock up when the timing belt breaks. Camshaft stops but crank keeps turning, so valves are stuck open or closed while the pistons continue to go up and down. If a piston and valve "interfere", you can't rotate the engine. The exception is when things break bad enough to remove the interference, it's unlikely your wife was driving in a manner to allow that to occur.
Since the engine still cranks, you probably don't have major damage associated with the "interference" style engines. The funny cranking speed is likely due to some valves being open all the time in several cylinders while the valves never open in the other cylinders. The result is basically no net compression throughout the normal engine cranking cycle.
I'm thinking Mitsubishi isn't radically different from Ford, GM, Toyota or Suzuki that I've replaced in the past. The biggest challenge is getting all the stuff off and out of the way so your can snake the new belt on and get it installed properly. You might have to replace a worn idler or tension adjuster along with the belt.
Oh yeah, draw a picture of how all the belts snake around the various accessories BEFORE you start removing them. Sometimes the diagram on the engine belt sticker (if it's still there) isn't correct.

According to Gates, it is not an interference engine. Look here:

I work with an Ex-Mitsubishi technician and he said the 2.0 liter SOHC and DOHC are both interference engines. He also said he has done a lot of broken timing belts on both engines and about 90% didn’t have a piston /valve interference when the belt jumps or breaks. Hopefully you’re one of the lucky ones.
I personally know if it was a G.M. car you would be definitely removing the head along with replacing the timing belt.
G.M. is still building “interference†engines, but they are with chain drives instead of belt drives.
He also gave me a web site that may interest some of you.

First off...Thanks for all the replys. It would have taken my post a year to get the same amount on the lame Mitsu boards I have found. I pulled the head last night and think I am in the clear. I didn't see any visible damage and no carbon was disturbed on either the pistons or the valves. Timing belt failed at 140,000 miles. They say change at 60.000 so guess I got my moneys worth. I ordered a new head set and belts, picked up a manual, and will install tomorrow.
Thanks once again!
Chris Todd
