Mine won't hold air either now but if I put a pellet (5mm) in it the leaking stops.
There is a "Youtube" video that shows how to replace the valve.
My Dad bought mine (now Daughter's) for me when I was ten. $19.95.
Sheridan "Blue streak." Many a rabbit...grackles...rattlesnakes and a host of other fauna fell to that rifle in the hands of a third grade kid back in the mid-60's.

"is there a way to oil some life back into the seals?"
Nope. Been there, tried that. My 60's blue streak started to leak a little so I tried oiling but used the wrong type which just made it leak faster. An easy to install seal kit made it good as new. If you go that route be sure to only use the correct type of oil to prolong seal life.

Yep it needs a seal set .I got my mine done 25 years ago by calling them and sending it back.

Just be sure that valve will fit your gun. I gather that there are a couple of different types.
I bought a kit and got my Silver Streak up and running again after it started leaking air some years ago.
It's not really a difficult repair, just be very careful not to strip the threads when installing the new valve. It threads into brass and you'll be fighting a spring while you're trying to get it started screwing in.

I've been able to bring many multi pump AGs back to life trying to work a little Crosman PelOil into the them. That oil actually can restore seals and O-rings back to life.
