I have a 2008 impreza, 2.5i, SOHC. I just replaced the blown motor with a used motor with 60,000 miles on it. Replaced all the timing components except for the cam gears. When I tried to start the car, the motor wouldn't turn on it's own. From what I've been told, the camshaft position sensor communicates with the raised bars on the back of the left side cam gear which come in 2 bar, and 7 bar varieties. My question is, how do you tell what kind of cam gear you need for the car to start? I don't have the original motor anymore as it was turned in for a core refund after we transferred over all of the accessories. Any other applicable advice is welcome and I can provide more info about the car as needed. 

 

Thanks in advance!

your car and the donor - AT or MT?
I think the trigger marks different between AT and MT's?

 

those are the trigger marks - the drivers side cam (for the cam sensor) and the crank sprocket both have them.

 

check part numbers/cross reference online.

call subaru and get your part number fo rthe drivers side cam sprocket using the VIN, or stop in and look at one if they have them in stock?

might be able to look up part pictures online once you get a part number.

Mine is a MT. I'm pretty sure the new motor was MT as well. But thank you for that. I hadn't thought of that.
