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..
