2006 Toyota Avalon Engine Ran with no oil filter 3,000 mile

Hello,

Went to Valvoline Oil Center and had the engine oil and filter changed, They noticed that there wasn't an in line canister filter to be removed. The Toyota dealership failed to install a filter last time I was in there for service. Good heavens.

Question, any damage from running a young engine with 18,000 to 21,000 (3,000 miles) without a oil filter. Everything seems to be running okay.

My thanks
