If you replace the crank gear the engine will need to be lifted, you will need a gear puller . The radiator, crankshaft pulley and oil pan all must be removed. Replacing only the cam gear will be easier . Being as it is such a pain in the butt job , would you ever want to have to go through it again ??? I've never had a problem with timing gear noise, no matter which gear that I used. If there was any noise, it would probably be very faint. Either way the stripped teeth will be a thing to consider . It may only be a few teeth. You may want to remove the oil pan again if its a bunch of teeth. the oil pomp has a pretty good screen but you will need to decide if there are enough stripped off teeth in the oil pan to actually block the screen .

The oil pan gasket under the timing cover torn off when removing the cover so I will have to replace the gasket?
