Gauze/filter in oil line/turbo?

[Ben]

I'm replacing my t2 with a td04 at the moment. When I took the t2 off I noticed what looks like a gauze/filter fall onto the floor. I'm guessing this has come out of the high pressure oil line, or out of the turbo where the high pressure goes in?

Anyone noticed this before? Just wondering if I need to try and resuse it with the td04, or whether the td04 will already have one in it?



Thanks
