ordering an opti tmw, and what all else do i need...does it require changing any gaskets to install?

Also, I have a front oil leak somewhere, and i was wondering whats the best brand/location to get a front timing cover gasket and front main, also what about the waterpump? are there any seals for dist. & water pump drive? can i get all these at autozone or local store or do any of them have to be GM?

another thing im not real sure off, can the timing cover be taken off with the oil pan on, without sacraficing the "integrity" off the oil pan seal.....is there a trick to this? if i have to take off the pan to do it right, is there a rubber pan gasket for the lt1s, i remember i had used corks on all my truck motors(like 3 or 4 swaps) and on the last one i used a one peice rubber one, it was awsome, didnt leak a drop, all one peace, no need for silicone or anytyhing.....

thanks in advance guys

 

I know you need 2 waterpump gaskets

can anyone help me on the gaskets? f/those pics it looks like the opti has a gasket too.....does that waterpump driveshaft have a gasket as well? I need to know b/c i've got a leak somewhere, and i just wanna do all the front gaskets while i have the opti and w/p off....
thanks....

 

the only gaskets you need are 2 waterpump gaskets.
the opti does not have one.
Just go to an autoparts store and ask for 2 waterpump gaskets for your car...if its a leak, then its the gaskets or the pump is bad

 

its a oil leak somewhere on the front of the motor that im trying to fix while im swapping the opti and installing a elec. water pump.

your telling me the opti does not have a gasket, how does it keep from leaking oil out of the timing cover? what about the w/p driveshaft?
