I'm just trying to figure out how it works and what is it is? Can someone maybe explain this to me?quq

Its all ur oil lines and fittings u need for their turbo.

i understand that, but how does it work if there is no oil pan tapping or drilling?

it drains into where the drain plug should be

link?

ok, so there is a replacement drain plug for return line, but what about sending line?

bump...

the sending line comes out of the head, theres 3 torx bolts in the back under the header, Im pretty sure they have theirs come from one of those
