4.7L new lifters possibly failing already
4.7L - how to pinpoint a bad lifter?
So I got what sounds like a lifter or two tapping bad ever since it turned "cold" here in ATL. Happened a few days ago and sounded pretty loud on cold start, but went away to nothing as the oil flowed up. Today it kept tapping for a 5 mile drive and was tapping when I pulled up. Parked, came back an hour later and it was perfectly quiet upon starting. These are new Sealed Power lifters I installed around April...sigh. Kinda glad it sounds like the passenger side, cause I had to loosen the brake booster to get the driver's side valve cover off.
Any idea on how to check 4.7 lifters without pulling them all out one by one? I suspect I won't see anything just eyeballing them.

Yeah, temps have hit the twenties, here in ATL. Even after sitting undriven for days, there is no valve clatter anymore. Strange issue.
