Im not a great fan of SNAKE OIL but admit ive had some luck with SEAFOAM. Its the first step id take. Just me - but id change ur oil to a 5-30 and add a couple of cans of the SEAFOAM and give it a 100 mile run. If u have a Valve sticking u might want to try a couple of can in the gas tank also.

Im in the middle of a 12 rebuild right now so can tell u the 12 valve train is a MAZE of many moving parts, thus ur noise could be many things.
