    2001 grand Cherokee Laredo 4.0
    So I have a 01 GC Laredo 4.0 and recently just replaced the CCV valve elbows(pcv) due to oil leak around both elbows and loud whining/ whistling sound when letting off throttle. No more leakage but still whines just not as long. Could it be the hoses or something else to do with vacuum? Please help
