I think this sentence doesn't make sense, unless you mean "switchin back to pennzo oil syn".
If you're suddenly getting valve noise you've probably mixed in the wrong type/weight of oil and need to drain it all out and start over again incl. a new filter.
Changing over to synthetic oil will not cure an older motor, and may even reveal defects (such as a worn valve train) more than a heavier conventional oil.
