Default 2.5 SOHC Timing w/o belt marks

Just finished reassembling my ej25. I marked the direction of the belt, but unfortunately my dumb ass forgot to put paint marks on the timing belt to match up w/ the marks on the pulleys before it was disassembled, figuring that there would be some clear marks on the block to align the pulleys before putting the belt back on.

Theres a mark on the block for the crank pulley, and seems to be a slot on the timing belt cover on the right side for the cam pulley. However, the only markings on the other side seem to be a small casting mark facing straight up. I just assumed all the marks would be straight up and threw the belt on..

Can anyone confirm this? Does anyone have the tooth count off hand for the marks between the crank timing mark and the cam pulley timing marks..? That way i can be productive rather than throw tools around the shop when it doesnt start..

2004 manual shows 46.8 tooth length between passenger side camshaft alignment mark and crank sprocker alingment mark. Then 43.7 tooth length from the crank sprocket to the drivers side cam mark.

Since when did they start measuring in 0.8 tooth lenght!?

2000 impreza and 2002 Impreza manual shows 44 teeth and 40.5 teeth.

Default Dont try to start

I do know this do not try to start if you are un sure of the corect timing. Take the spark plugs out and do it by hand. If you feel the piston hitting on a valve you will not bust it. Sorry I dont have any thing other than that, good luck.

hahah funnies!

take your timing belt to a auto parts store, have a marker/pen/PAINT PEN with you can ask them you want to look and compare the NEW one to your old one and put markings on yours. Then you just put markings on yours when placed side by side via tooth. I've gone to NAPA for this a couple of times with my paintpen.

Thanks for the info..! Turned it over by hand a few times before hooking everything else up.. Car starts and runs, which is more than i expected given the number of beers consumed in the shop tonight..

Isn't this a non-interference motor..? From what i've read the only problems were on the DOHC motors with valves hitting each other w/ misaligned cams..

And .8..? Man the "that looks about right" method just doesn't cut it anymore...
