I've got oil leaks from the valve cover seal washers (the rubber bits under the valve cover nuts).

I've got an inspection II imminent so I'll get the valve cover seal washers replaced by my indy during the inspection II.

I'm wondering if people think it would also be worth getting the valve cover gaskets replaced at the same time? Given the age/mileage of my car, and the fact that access will be relatively easy duting the insprection II, would it be foolish not to replace the valve cover gaskets? Or should I tell my indy to only replace the valve cover gaskets if oil has seeped into the spark plug cavities?

Thanks.
