bought this motor second hand, and is the oil pump gear thing supposed to touch the crank sprocket? there is a line on the crank where the gear was a little bit under 1/8" away from the sprocket.
The engine I just disassembled, [2005 L33], appears to be an original GM build piece.
The crank sprocket, and the gear are a 1 pc part.
The aftermkt timing set I am using, uses an oil pump gear like yours, and it slides back to the dbl row gear.
do i try to tap it on? nothing appears off with the pump gear, maybe ill try to mess with the keys.....question, what id its that way to allow space for a double roller for some reason? my timing set is a cloyes hex adjust

Yes, try lightly tapping it back. It should mate against the timing sprocket. If it won’t move, as suggested above, maybe the key is burred, or not set in its register properly.
Ok some tapping got it seated so we are good. So I have an uneasy feeling about this cloyes adjustable set, only because I can't figure out how it holds the timing after you adjust it. It also seems odd how the bolt holes are egg shaped, I mean I know it has to be that way, but what prevents the Allen screw from moving thousands of miles down the road. Wish I could use a standard set, but don't think I could get 4 degrees advanced with the stock set up can i?
If your ordering something else, consider a billet set like a Rollmaster. WS6Store has them for best price I could find. Comes with a nice Iwis chain. That will give the +4 advanced your looking for, and a lot of other degreed key way settings that won’t move. Perhaps your camshaft already has been ground with some advance built in?
No I went back and the card says it has the 4 degrees advanced ground in so I should be good. I'm goona go ahead and order a new gm cam sprocket. I shouldn't need this adjustable and I already have a new ls2 chain. But I should probably replace this. Somehow didn't see it until after I put it pn, but that means pulling off the crank pulley
