Problem with Timing belt
Well im having the useual timing belt issue about it being loose, but this one is WAY to loose
This is what i have done before checking the belt.
Replaced tensioner pulley
Replaced tensioner
Replaced timing belt
So im thinking that the tensioner pulley has an offset hole and it could not be where it is suppose to be? i can litterally put the timing belt on by hand without using the tensioner and everything is decently tight. but when i try to turn the car over by hand after a few rotations if i stop the exhaust cam gear keeps jumping teeth.

Yup, you got it right, there is an offset hole in the tensioner pulley.
To set you need the special tool MD998767 and a ¼ inch torque wrench. Pull the tensoner and pin it. Then reinstall. Loosen the tensoner center pulley bolt and using the special tool turn the center of the tensoner pulley counter-clock-wise until a tension of 36 ft pounds. Hold in place and tighten the center bolt. Now, pull the pin out of the tensioner, crank it over about 2 times by hand and let it set for about 15 minutes.
Either check that the tensioner plunger protrusion is exactly between 0.15 and 0.17 inches or that the pin can be slid back into its hole easily. If so you are good to go. Otherwise, go back to the top and start over. It usually takes me a few tries to get this right.

I tried looking for part number MD998767 but got no results in www.mitsubishiparts.net
Well, I made the mistake of looking it up in the Mitsu Service Manual.
I think if you search for timing belt tools you will come up with it. There is a long threaded piece and the little piece you need with the two prongs. I've had mine since my DSM days.
