It was a Mobil 1 M102a filter. I noticed some lifter rattle before changing oil today.
I installed a Fram filter today and the lifter rattle seems to have disappeared.
So hopefully issue solved.
I guess I'll never purchase a Mobil 1 filter again.
You mean like from a dry hydraulic lifter?
The '07 - '09 engines just used bucket tappets, no hydraulics involved, so lack of oil pressure wouldn't have caused "lifter rattle".
If (for whatever reason) you heard a rattle on startup that quickly went away, it was more likely rod bearing knock that disappeared as soon as oil got to the bearings.
The location of the oil filter on the '07-'09 engines made it very convenient to change, but created a very long (4 feet?) oil gallery from the pump, all the way to the filter at the top of the block, then all the way down to the crankshaft, which then supplied oil to the rod bearings.
The 2nd gen 1GR-FE relocated the oil filter to the bottom-front of the block, just a few inches from the pump, and a few inches from the gallery feeding the crank. But that also made changing the filter a PITA with full skidplates installed.
I think the anti-drainback valve in your filter somehow failed and allowed the filter to drain completely at engine shutdown.
Personally, I'd stay away from anything other than Toyota EOM filters. I've got nearly 600,000 total miles spread across several different Toyota vehicles, using only Toyota-branded filters, and never had any filter or lubrication system issues.
