PCV hose looks good, but gasket looks leaking as shown in the attached pic. Got six trouble codes:
: Fuel pressure high or low; MAF sensor dirty/defective; Vacuum leak on engine; Leaking fuel injector or fuel pressure regulator.
: If bank one and two are set together suspect a fuel pressure condition or MAF sensor fault; Failed H02S21(Heated oxygen-Bank 2 Sensor 1); Ignition misfire condition; Fuel injector problem; Engine mechanical condition.
: Misfire on bank 1; Vacuum leak affecting bank 1 only; Fuel injector problem bank 1; Engine mechanical condition.
: If bank one and two codes set together suspect fuel pressure or MAF sensor; Oxygen sensor defective; Ignition misfire-repair; Fuel injector problem.
: Defective, loose or missing fuel cap; EVAP canister broke, hose cracked or not connected; Purge or vent solenoid defective; Vacuum leak at engine.
: Defective or loose fuel cap; EVAP canister broke, hose cracked or not connected; Purge or vent solenoid defective; Vacuum leak at engine.
Could you tell me what should I do? Many thanks.
