What you see here is the result of an XFi camshaft-ectomy, freshly performed on the Firefly (and also its stock, garden variety camshaft).
It's not too big a job to pull a cam out of these motors, so I'm swapping it over to the Metro.
I'm doing it the "easy" way, having cut the tops of the timing belt covers of both cars with a dremel to expose just the cam gear. Otherwise, to get the belt cover off, you have to remove the crankshaft AND waterpump pulleys.
The "easy" way leaves the timing belt in place, while you delicately slip the belt off the cam gear once the cam is loose.
The risk of doing it this way is: what happens if the timing belt slips/jumps on the crank gear while the cam is out of the engine or while you're messing around trying to get the belt on/off? It turns into a bigger job, that's what happens.
