Saturntech9. The engine started making noise under the valve cover on passenger side of motor when first started cold. REALLY LOUD! Noise goes away after 30-45 seconds. My mechanic pulled vavle cover off and averything looks good. Timing chain is tight and nothing lose. He thinks that a lifter is not pumping up properly. Can these be changed and how hard is it? Does head have to come off? Should I change all of them? Thanks sw1 didnt know how to email you directly.
