quote Originally posted by phonedawgz: idk why the Service Manual says to do it with cam on the base of the lobe. Perhaps they feel the extra pressure will affect the torque settings. idk. I hear ya when your talking about tightening down to a collared stud. I'd prob do it the manual way just to make sure I wasn't screwing up something however. When giving advice I tend to caution even more and go with the manual.

I here you, better safe then sorry.

As for the manuals, they tell you to pull the motor to pull the camshaft to replace the cam gear, but if there is a threaded hole in the end of the cam, it can be done another way.
Now I never did this on a Fiero yet, but I had an 86 Grand am with the 2.5 and the gears were noisy as he!!. Remove stuff in the way on front of motor, remove balancer, remove timing cover, pry on gear to break the fiber part off, cut groove in metal center of cam gear that is left on the cam with a dremel near the keyway, smack with chisle to split, slide off, align new gear, 3/8 16 bolt and washers with a nut to press back on, reassemble. Four hours or less, done.

Yea...we had the helicopter on stand-by, along with a fire extinguisher!!

I'm also going to pull the timing cover...just to double check cam/crank star allignment...will post later!!

I assume you set the timing the way I detailed. I didn't hear if that made any difference or if it was dead on already or what.

Let us know what you find on the cam timing.
