First off, I'm an idiot for being lazy. (That out of the way)

I was aligning the crank and cam sprockets. I had already taken the crank pulley off and didn't put the bolt back in the crank to turn it.

So I needed to move the crank a little more to align the cam sprocket, so I figured if I just did it slow on the upper right cam sprocket bolt I could move it into position. (It slipped on the belt? ) now I can't align anything as I believe i feel a valve hit the piston as I slowly turn the crank.

Is there any way to get me out of this? (pull the heads???)

Sorry, 1999 Outback legacy wagon limited.

Forgot to put vehicle info

Turn the cam back to where it's supposed to be. It didn't go far, maybe 1/4 turn at most, so it shouldn't be hard to turn it back to the proper position and then put the belt back on so you can turn everything at the same time.

 

Valve damage is a possibility, but you won't know until you get it put back together and start it, or do a leak down test.

Don't panic.

 

If you were turning by hand and stopped as soon as there was resistance, there is most likely no damage. Turning it by hand i doubt created it by force to damage anything.

 

Do like was mentioned above.

You can slip the belt up to three teeth without doing any damage. If you went further than that, you must be very careful. First, put the crank bolt in and see if you can get the crank to the timiing mark. Once you have it ther just take off the belt and unspring the cams and you will be safe. If you feel any resistance wait a moment to see if it is just compression in the cylinder. If I were you I would procede very carefully.

 

you could also carefully take off the belt and then turn the cam in the opposite direction that you were going before until it is in the unsprung position. now the bvalves are closed and in no danger. Once you have all of the cams unsprung you can turn the motor and get the marks lined up.

 

Good Luck

if the crank sprocket was in the correct timing position, or close, you are probably ok. when it is in that position all of the pistons are at the mid point and the valves should clear. but if the crank sprocket was not in or near the correct position you will have to wait and see.

 

however, since it is a double OHC, it is isn't it, the valves on one cam could be bumping the valves on the other cam.

Although you haven't removed the heads, the part entitled "Assembling 1997 And Newer Engines" in the following article might be helpful in getting things properly aligned without damage (which hopefully hasn't happened already).
