PVC Check Valve Hose

Question for those in the know. I have upgraded all my vacum hoses with silicone and recently replaced the PVC check valve. Have noticed something peculiar with the hose associated with the check valve from the intake manifold to the valve cover. It seems to "sweat" what I think is oil. Noticed on my buddys aero this hose is covered in a foam insulator. On mine I have none. the hose sweats on both sides of the pvc valve and I have no leaks of oil in the engine compartment. After a wipe down all is well but a few days later it seems to condense again. Not really worried but just wondering why. Any ideas? TIA
