swampy
hi
Ryco have recently modified there c/cans
Old Rcc 350
New Rcc351
1st mod
****filter has one end [bottom ] 90 % enclosed
Why I suspect to restrict oil slosh from being sucked into outlet which is at the other /top end of filter
2nd mod
Outlet located at top of filter has alot larger baffle
WHY,, To prevent excessive oil from being sucked thru c/can ie slow the air so it can return more oil to storage area
3rd mod
pressure regulating valve located on the top out let
Function ,, to protect filter media against un needed pressure waves
problem ,, this restricts flow
solution ,, the later Rcc has this removed

Thanks Swampy, but IMO a better solution is a Mann-Hummel Provent catch can, properly engineered from the start. From the start these cans have addressed all the issues Ryco and others have progressively dealt with to make their cheap options come up to scratch both legally and performance-wise.
I use these guys
Link, but there are plenty of other retailers.
Not cheap but as has been said here before, buy right, buy once.
I had one in a 120 series Prado 3L diesel, prone to coking up the intake system and after 170,000km it was clean as a whistle. Ditto my current BT50 3.2L diesel at 140k.

Frank P, I have used the Provent and now use the Isuzu factory catch can, cheaper for the initial buy, filters are a lot cheaper and by design, I think a better item. Isuzu Oil PCV Separator, Part number: 8-97324682-1
Filter part number: 8-98002346-0
