I have had the valve cover gaskets replaced at least 4 times. Both sides. Yet, still leaking. I think it is an engine pressure issue but my mechanic does not thinks so. I am not getting any errors, just smells like old chevy. Also, found oil past air mass sensor that appeared to be coming from heater hose.
have the same problem?
