For a 98 ls1. Specifically items 273 and 274 pictured here. Plugs into the top (rear) of the driver side valve cover. No longer stocked by GM

274 is just a generic grommet, then you could fab something yourself to make the other piece hook to your stock lines.

Or you could find a newer style setup like this and retrofit it to your lines if thats easier.

As the OP has a 1998 engine, those center bolt valve covers won't work.

Andy, unless you're restoring a vehicle back to dead stock for show use, I HIGHLY recommend you consider going to the LS6 PCV setup. Waayy better.
