Ticking Noise Right Hand Valve Cover 560 Sel

[TOPGUN]

I Recently Replaced The Chain, Guides, Tensioner, (mb Tensioner) Cam Oiler Fittings. Cams Line Up At Marks On Cam Towers With Crank At Zero. Had Over 10 Deg Stretch Now Have 1 Deg Or Maybe 2 Deg. Engine Starts,runs And Idles Perfectly. The Problem Is On A Cold Start There Is Noise Or Rattle From Right Valve Train. I Removed Valve Cover Could Not Any Loose Or Damaged Rockers Or Ball Studs. This Noise Only Lasts For About 1 Minute.after A Perceptable Click, Noise Instantly Is Gone. On A Hot Start No Noise Is There. Could It Be A Lifter Drained Down That Would Take A Full Minute To Pump Up? This Noise Was The Reason For The Timing Chain Replacement Work. I Searched The Posts For Ball Stud And Rocker. There Are Many But Nothing Like This. I Hope The Forum Brain Trust Can Help Me. Thanks Topgun
