Can anyone tell me what the purpose of the part in the pic is. This is the metal plate which sits inside the cam covers on an R33 GTR.I removed the metal plate from iside the cover but unfortunately on one of the plates i broke 1 of the small brown plastic type tubes as seen in the pic ( pic is of the good one--unbroken )..What purpose do the brown tubes serve and do i need to replace te parts/parts.....Im desperate to get this back together again....

I would say it separates oil from air. Half way up in the top of the cam cov er, you should have a mesh strainer. This tries to remove some oil from the gasses escaping through the breathers.
The brown tubes direct the oil running down the top edge of the plate to run into one of the return galleys.

It will still work ok with 1 broken.
