Nah i did the same man...im not arguing but like im just speaking from experience. The only problems i had with the kit was the BOV leaked 1 week after install, the exhaust manifold started cracking 6 months in up until 1 year where it fell apart and the turbo seal blew a bit over a year of use.

I havent got anything left from the original kit and it served its perpose but if i was to ever to the process again or if i could rewind to the past i would have bought quality from the start.

But we all learn from our mistakes.

i dont think its a swarf, i cleaned out the cooler pipe when i removed the bov...

Im soo lost hey all i can think it can be is the the mechanical side in the bov but i pulled it appart and it all seamed to be clean and moving fine.
