Default cams gears moved

I did some searching and found nothing. I was replacing my timing belt tensioner on my wrx and forgot about the drivers side gears wanting to move when they are not under tension. I took the tensioner off and they moved. How do I get them back in time? Is it as simple as lining the marks back up on the gears? Which way do I need to turn them etc?

So you went to do this without having a factory service manual on hand? Not a good idea. Go to the Subaru tech site and download it now, the procedure for setting cam timing is in there.

Does the belt still have the marks on it? Line the marks on the belt up with the correct marks on the sprockets. And of course make sure the marks on the crank sprocket and passenger sprockets are correct as well.

just rotate them back in the opposite way the spun, what ever you do dont rotate them in the same direction as they spun, ie 360.

Do you know how the marks line up, i can explain it...but im not gonna go throught it if you know how they line up because it takes to long to type it.

If you do a search in this forum, for my username and cam timing and DOHC, ive explained the DOHC procedure many times, its the same for N/A or turbo, only thing in the WRX is you have to remove the timing belt metal belt guards in the lower corners to make it easier to line the belt up.

If the belt doesnt have the marks on it anymore, your gonna need to go get a new belt.

if you went through all the trouble of changing the tensioner why didnt you do the belt as well?

Disclaimer, im a professional, use any procdure i have posted online to line up the belt at your own risk, i have alot of experience doing these and dont recomend doing them without proper supervision. Timing the motor wrong can result in bent valves and motor failure. This I will not be held liable for

McDade: you need to make the text smaller if you want it considered as "fine print". Otherwise, we will begin to think you just like typing.

The marks are all still there. The car only has 22,000 miles. The tensioner is clearly bad. The belt looks brand new. Should I spin the intake back first or the exhaust or does it matter? I can't remember which one moved first. The reason I ask is because is it possible for the valves to overlap each other and by just turning one sprocket I might bend the other valves. Basically I just need to line all of the marks on the belt and sprockets up right?

I have a Subaru WRX manual on a cd. It doesn't tell you what to do if you screw up.
