Underdrive Pulley Question
If you check out my oil leak post you will see the pictures below. Looks like I need a new pulley. What should I do?
OEM? ATI?
My crank is pinned for an OEM pulley, so would an ATI setup even work? If i need to stick to the OEM style, is the LS2/LS3 pulley the same? Is it better? I know the new LS3 seal is better.
Basically I don't want this to happen again. I also don't want to spend the money on an 8 rib setup right now. Maybe that will come when/if I build the motor down the road.
Part numbers (if you have them) would be awesome

I decided to go with PB but with stock size. I didn't trust the OEM as it developed the wobble, even with low millage. I changed the front seal and oil pump, timing chain while I was in there.
