Hey, Well I have a little problem or question I guess.
I just replaced my timing belt and, I'm thinking i might have used the wrong algnment marks.
I used the little notch on both the cam gears and put them facing one another toward one another. The crank gear i put on the V and the gear had a little triangle to aline that to.

So I this the right way of putting things a TDC or not? Because now that I look at my cam gears the notchs are not aligned anymore and the engine seems to not read even rpm's when I hit 5000 and just jumps to 5500 or 6000.

Can you let me know whats up or if im burning valves here.....WTF

Those little notches should be 180* from eachother. IIRC, The exhaust cam gear should point up while the intake gear should point down.
 
If the car is driveable than you don't have a bent valve, but I would seriously suggest re-timing the car. You might be very lucky to have the timing off perfectly (a mess up that didn't cost you a valve-train).

My advise on where to put the timing marks could be wrong, but I will check the haynes manual tomorrow night (I left it in the rain) and see what that says to have the marks at.
 
If you are talking about the notches in the cam gears. The timing marks they should face each other.
 
So in short if i placed them toward one another like so ~ >< ~ then i have either bent a valve or the intake/exhuast is staying open longer then it is supposed to, and they arent alined like that since i have driven the car. So is it possible for them to aline correctly by them selves. Because the car is drivable, but it is just losing power due to this or is it throwing flames into one of the manifolds:confused:....
 
Sounds to me like one of the cams moved when you set the tension on the timing belt. Rotate the crank till the timing mark for the crank lines up and see how far the timing marks for the cams are off
 
well when i set the tension on the belt i made shure they alined by setting them a tooth off so they would aline. But they were alined when i turn the motor around twice. But now they arent, and the hesitation in 5000 rpm's makes me wonder what happened.
 
Re align and make sure the tension is set properly. and yes the marks should face each other but only if the dowels are straight up on the cams. Mitsubishi put two marks on the cam sprockets so they can be used on either cam. so make sure the dowels are pointing up.
 
There seems to be some confusion as to what marks you used to set your timing so how about you show us on a picture

edit: picture coming up in a couple

Did you do it like this

My guess is if you set the timing right, you didn't get the tension right

ok so I did they alignment correctly. I made sure that I set the timming on marks when i set the tension with the hydrolic, which isn't leaking. There are red dotes i saw on the gears so maybe those are the marks i need to use.
Is there a way to take off the valve cover and tell which cam is open and at tdc??
 
Did, you install the cam gear with the correct side facing out? One side will say 2.4L and the side you want to use will say 2.0L. Have the side that says 2.0L facing away from the engine.


There is not really a way to tell if you are TDC by looking at it in the car.
 
this is on a car without performance cam gears. it's a 2.0 420A. It has the normal notchs and someone added red dottes to them.

so is there anyway to tell if the cams are at there correct alignment by not looking at the cam gears, or anyway anyone can give me anyother way to tell.

With the bolts that hold the gears on the cams out, you make sure they are how everyone said. One dowel up, one dowel down (I forget if it's intake up/exhaust down or vice versa) Your marks if you're using the correct marks, should be lined up when you set the cams this way. Then tie the cam gears together and reinstall the bolts (torque properly) Recheck your marks, install belt, 2 rotations check your marks. If it's still good, go around a few more times to make sure everything stays lined up. If so you're good to go.
