37 Packard 120 valve noise

Posted by SCPACKARD On 2016/2/28 13:29:35

have awakened a 1937 Packard 120 after 20 years of storage,experancing excessive valve chatter. does that mean mechanical lifters need adjusting? are lifters worn? does that sound like a valve job is needed. Have used Marvel Mystery oil car runs but doesn't sound like a Packard.
Any suggestions appreciated Byronnsc@aol.com
