oil pressure is fine, the tapping noise is comming from what seems to be driver side maybe #7. I'm going to drop the oil and look for particles. thanks, Jimmy C. ----- Original Message ----- From: [EMAIL PROTECTED] To: [email protected] Sent: Tuesday, August 14, 2007 3:18 PM Subject: Re: [Chevelle-list] Vacum
How is your oil pressure? I had a knock in my 454...Oil pressure was fine, so I knew it wasnt a rod knock. LONG story short, it flattened out the cam...which is notorious in BBC's from what I hear. I would check your valve lash...if one is really lose, there's your problem. It would most likely be the number 7 or 8 cylinder. -----Original Message----- From: Jim & Chris <[EMAIL PROTECTED]> To: The Chevelle Mailing List <[email protected]> Sent: Tue, 14 Aug 2007 11:59 am Subject: [Chevelle-list] Vacum I am finally getting back to my Chevelle , rookie question but here goes. which is the best port to measure the vacuum and what should the vacuum be ?
