I am getting ready to replace the timing belt on my EJ25 DOHC.
One question I have is about the camshaft locking tools that Subaru sells for hundreds of bucks. I can't afford them, but it does sound like the job is easier by locking down the camshafts so that they cannot rotate when removing the timing belt. This will likely be a one-man job, so I want to make it as easy as possible to reinstall a timing belt.
My question is, when I remove the belt, will the camshafts on the driver side cause damage when they are released and spin? Sounds like they are under tension and will spin, but do they need to be locked so as not to cause valve damage?
I am considering trying to rig a camshaft lock using socket wrenches, but am not sure if this is really necessary.
Thanks for any replies!
