I have downloaded and read the Subaru Product Campaign Bulletin #WTY-84 which states on page 10.
IMPORTANT: Always keep close watch for any loose pieces of sealer, large or small as components are disassembled and remove them right away. This will help prevent them from getting into oil passages, restricting oil flow and potentially causing damage as shown here.
Pictures are in the bulletin.
And another on page 14
VERY IMPORTANT: It is critical to make sure all the original sealer is removed and the affected sealing surfaces completely clean and dry before applying any new sealer. After cleaning, a thorough inspection of the inside surfaces of the cylinder head area around the valve springs, inside the front timing cover and inside all the cam caps for any small pieces / bits of removed sealant or any other contamination is essential to providing a quality repair. Any contamination left behind can cause the Check Engine light to illuminate and / or other issues to develop resulting in a comeback.
I could not find any statement that suggests leaving "any amount" of sealant in the engine is acceptable.
It does however state that a quality repair includes making sure there is nothing left behind.
