Hey guys, I did this last night, and it just sounds like I've blocked off the BOV as opposed to venting it. I used the filter below...It seems to be filled with foam as opposed to a 'pod' filter so my guess is this pain in tha a** thing doesnt let enough air through... thoughts? I couldnt find one of the filters from the original post? only little pods with an inlet too small, not the 25mm. cheers. http://thumbs4.ebaystatic.com/m/mUa2koc0segJiiwyDVnE2HA/140.jpg http://www.ebay.com.au/itm/Monza-MEABB-High-Performance-Oil-Cap-Mini-Pod-Filter-Black-/120812175383?pt=AU_Car_Parts_Accessories&hash=item1c20f78017
