What are the consequenses if you rotate the crank and cams after removing there timing belt? I must be the only one who has had trouble after a belt change (actually did it to replace crank and cam seals). The belt is aligned properly- I've reset it at least six times. I did move one camshaft when it was disassembled- later I read not to do this- could cause hla bleed down. Would this cause any issues that would make the car not start? Turns over but wont start.

Hi there,

Do you know the engine code? That would be a help. If all the timing marks are correct, I would first do a comp check to prove compressions. Then check for spark, Injection pulse and fuel pressure. You may off dislodged a sensor wire, crank angle, cam angle and ecu has not got input signal. A ecu code read will help as well.

Subarus are interference motors, if you turn a cam far enough without the belt on you will bend valves and lose compression. If you tuned the crankshaft with the belt off you could have bent quite a few valves. If you have a dual overhead cam motor you need the special tool to index the cams after removing the pulleys. If you didnt have the special tool I assure you the pulley is on wrong and your out of time regardless of what the marks say.
