Okay, I'm still not convinced I should risk a good running engine by doing the timing belt myself.
This engine has 4 valves per cylinder, and they're driven by 4 camshafts, two camshafts on each side. The valves, which are small and delicate, can hit each other, not just the pistons. The valve spring pressure can turn the camshafts when the timing belt is removed, if a camshaft tool isn't used. And I'm not adjusting the valves at this time, probably.
So, "Other" Skip and whoever is kind enough to read and respond to this, does this sound like the kind of job you'd risk? Is this multi-valve engine identical to yours?
