On a '94 GT Legacy Subaru i went to do the crank seal and loosened up the belt. The cam on the drivers side spun i went and re-aligned it to spring tension and it was about 10cm off the mark at sp

You have not set it to the factory spec, and its probably 180 degrees off. Rotate the crank to top dead center (the mark on the crank toothed pulley, align the cam timing marks, refit the belt THEN release the tensioner. Rotate the engine manually to verify that all the timing marks realign themselves.

was the timing belt broken?

Are you sure the cams are aligned correctly?

If the belt was broken It may be wise to do a compression test. This should tell you if a valve has bent.

I assume that you mean the cambelt idler bearing.Ok if you are sure that the timing is correct for all cams(DOHC)?.Then the problem may be bent valves caused by the bearing collapse allowing the cams to go out of timing and cause valve strike.
I would recheck the timing,ensuring all marks line up precisely,the only one that should look 1/2 a tooth out is the crank.Genuine belts are always preferred for these as they have all the markings on the belt to align all the cams and crank,some other suppliers do not have this
I hope that this helps you,or get back to me with your findings.

did you know how to replace timing belt it has to be installed in a specified way or it wont start
if it broke and you replaced it then the story is different as if it breaks while running usually it also bends your valves you should see a technician for this

Replacing the cam seal is really more time consuming than difficult. The EJ-25 motor requires the removal of front covers, timing belt, and the timing gear for the cam that needs replaced. The seal can be replaced without removing the valve cover or cam. The installation is very important on setting the cam timing. Good luck and have a great day.

This requires cam belt(s) removal in order to access the seal behind the crank pulley/balancer. The front of engine comes apart including all belts, covers,pulleys and gears.Do fully understand there is special cam timing marks when setting back up ....look for three small dashes 30 degrees or so from tdc (zero) timing marks on the back flywheel

If your going to do or get this done you need to replace the camshaft seals crankshaft seal and water pump plus the idlers and tensioner.
If its a quad cam you might just want to leave it to the pro's........

all marks need to be aligned to 12 o'clock driver cam should align with notch in cover,crank sprocket also at 12 o'clock there is a straight line on reluctor of crank gear ,this line matches a notch on the oil pump where the crank sensor fits,right cam at 12 line should match camcase where it meets cylinder head

your timeing marks are on the block rite abouve the cams on either side and on the block in the middle but line the center mark on the teeth there is a mark not the arrow the arrow is where tdc is the mark is on teeth good luck.
