Oil and Coolant Leak Issue After Head Gasket Replacement

[SubieDoobyDoo]

4-5 months ago I replaced my head gaskets on a 2012 Impreza. Immediately since the head gasket job I've had an oil and coolant leak. I was told that I need to drive my car. Now I'm being told that I have a 1.) PCV Valve leak and it's not holding pressure 2.)Engine block oil separator is leaking oil and coolant (they want to replace the oil breather and coolant assembly) 3.) Something with a leak near the water pump by the cylinder head gasket/sealant/upper oil pan sealant.

Is any of this related to a head gasket issue? Am I getting taken advantage of? I was told my oil and coolant issue was a head gasket problem and now I have all these problems after spending 5k.

After the inspection I'm being told I need to replace the PCV valve, coolant bypass assembly, clean throttle body and engine front cover gasket. Does any of this related to the head gasket?
