mine is leaking , was going to get the timing cover set ( napa said that one was in it ) but it does not have one in it, thanks

 

It's just a little blue o-ring. Go to any GM parts department and they will have it. It's only a dollar and some change.

 

I think he means the larger seal that seats in the tming cover, not the O-ring seals on the shaft. I got mine out of the felpro timing cover gasket set, about 14 dollars at autozone. I couldnt find one seperately.

Not the o-ring, but the cover seal:

1995-1997 front cover opti seal GM p/n 12552428

 

it's the one that is attached to the timing cover, should I change the one on the shaft also? thanks

 

Looks like he has a 94 so it's:
Timing Cover Opti Seal GM 10128317 [95^ is 12552428]
Opti Drive Shaft Orings 10474278
Yes replace the Orings too they are cheap..

 

Thanks Charlie. Guess I looked at one of the other sigs.
