Be forewarned, though, that the oil pump drive can be a bit of a ba$tard to remove... and there's a trick to installing it.
The o-ring can hang up- I've removed them by clamping vice-grips on them and prying up. Also have driven a screwdriver under and pried- it'll make a burr that you have to file off.
When you go to reinstall it, put a little grease on the o-ring and in the hole. The hexagonal oil pump drive shaft may or may not realign properly when you reinstall the drive- if not, you have two options.
If you're feeling brave, unplug the wires to the coil packs, have a buddy bump the starter a few times while you gently push down on the drive. It'll drop into place when things line up.
If you're feeling patient, then you can keep re-trying to install the drive in different positions (one gear-tooth at a time) until the hexagonal shaft lines up. Usually takes a few attempts.
Either way- that hex shaft might come out with the drive, or it might stay with the pump... I've had them do both. If it stays with the pump... then no worries. If it comes out with the drive, then make sure it's firmly inserted (squish it in there with some grease if neccesary) so that it doesn't fall out as you install the drive.
