A kid I know toasted his 2000 Protege 1.8l very badly. I got a head from a junk yard and had it surfaced. However, the yard removed the cam sprockets so all I had was the intake and exhaust cams left in the head. No problem I thought. I just popped the sprockets off the old head and placed them aside. I knew which was the intake and exhaust because I had marked them with white paint so I could read them clearly when it came time to realign them. When I went to reinstall them on the replacement head, as i turned them over to find the hole that locates the pin on the cam, I was surprised to find that there is not one hole, but a V groove on each sprocket, which allows in essence two positions on each sprocket. I freaked and went back to my old cam and found what I believed was the correct position on each based on a 'clean spot' on the old cams, but honestly, I'm not sure. The car still won't start. Anyone out there have any advice .. Preferably experience as to which pin hole on each I should be using? Thx!
