Re: [Chevelle-list] Ticking from #4 Cylinder :-( (addidional info)

That can be a leak at the header.  With no spark, there is no explosion, and no big puff out the header.  When the noise is happening, put a few foot long piece of heater hose or similar tubing all around the header flange and follow that pipe to the collector.  If there is an exhaust leak, you can find it that way really easily.  I have had them before and thought it was a lifter until I found the header leak.

If i remove the spark plug boot from that cylinder the ticking disappears!   Would you give the same diagnose with the additional info above?   How do I adjust ther rocker arm?   Pelle ----- Original Message ----- From: Dale To: 'The Chevelle Mailing List' Sent: Monday, July 31, 2006 5:53 PM Subject: Re: [Chevelle-list] Ticking from #4 Cylinder :-( If it’s not an exhaust leak and you can’t adjust the noise out of the rocker arm, could be a flat lobe on the camshaft, had it happen to me. Lifter would never adjust and turned out to be a flat lobe.   Dale McIntosh From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Shawn Price Sent: Monday, July 31, 2006 7:19 AM To: The Chevelle Mailing List Subject: Re: [Chevelle-list] Ticking from #4 Cylinder :-(   Usually a sound like that is an exhaust leak from the header, a lifter not pumping up or a rocker arm that needs adjustment.   --   Shawn   On Jul 31, 2006, at 7:58 AM, Pelle Andersson wrote: What is the most likely cause?
