Did you get a new o ring? the new one is blue and the stock one is black. I had tapping after my cam swap and did a bunch of searching and got a new o ring, lined it up perfect and the tick was gone. the new o ring is also thicker than the stock one, GM changed to the newer one I think they may have realized it needed to be a bit thicker.
Did you figure out the problem? You are kidding about using a hammer to install the pulley........right?

Yeah, I got the new o ring. The guy at the dealership just gave me one because he was busy! Guess he didnt have the time to ring it up! Got everything taken apart, and I'll get it back together tomorrow and see what happens!!

I did use a hammer. But just tapped a little bit and then tightened the bolt. It worked great....just took a little time!

My oil pressure is at 40lbs idle. Is there anything I can do to make it stop before I pull the head?
Did you replace your valve springs? Thats a pretty hefty cam to be using w/ stock springs. If you did replace the valve springs, are they set at the correct pressure? If not, that could cause "clearance" in your valve train and therefore, tapping.

I really don't think the tick is due to low oil pressure. When you install a larger cam than stock, it is not uncommon for the oil pressure to drop like that at idle. I'm not sure why, I just know it does.
BUT.......did you do anything different with the valve springs??
That cam is definitely pushing the limits on stock valve springs. I would start there....
I fixed it. I replaced the old o ring with a new one. The old ring was not pinched at all, but it was smaller than the new one. Oil pressure at idle is 40lbs and goes up to 60lbs when I get on it. Thanks for everyone's help. B.J.
