Camshaft seal question

Finishing up cylinder head rebuild after burnt valve. Car is 1999 V70XC, 2.4 turbo. When I pulled off upper valve cover, there was not a seal on the intake cam free end (behind plastic plug, drivers side) and the cylinder head gasket kit from FCP does not have a seal for this end. Am I missing anything? Is there no seal on this camshaft at free end?

I've never worked on one of a 99 engine with VVT but the Volvo parts diagrams say the same thing - no rear cam seal.

Just curious: does the exhaust cam even stick out back there, or is it inside the cam cover?

It's in the cover with the cam sensor pickup rotor sticking out into camshaft position sensor. Essentially same length as intake cam, arranged with slots for locking tool (after sensorrotor is removed). Had no oil leakage, but there is machined area for a seal, wondered why one was not in place.

Thanks for the details. Yeah, I wonder too.

Somebody who's worked on that engine will chime in, but seems like there isn't a seal.
