datsun dave Posted July 21, 2009 Share Posted July 21, 2009 How do i get the original breather metal fittings out from the RB26 cam covers ? As have bought some new fittings from a Hybridz member so i can run them direct into a oil catch can with breathers using some nice braided lines & fittings. Thanks chaps.

RB26powered74zcar Posted July 21, 2009 Share Posted July 21, 2009 Just put a large round drift into both holes on the fitting and turn back and forth while pulling upward... they are pressed in. Or... like I did, from underneath, use a large drift to pound it out. Quote Link to comment Share on other sites More sharing options...

stony Posted July 22, 2009 Share Posted July 22, 2009 Turning them out you have to clamp the covers down and there is a chance of scratching or damaging in some way. take the internal baffling out and use a large diameter flat punch from the inside one good wack and they should go flyin.

gmac708 Posted July 23, 2009 Share Posted July 23, 2009 I am using the McKinney mounts and found the fittings were very close to the hood catch. Not much room if you ever want to remove rocker cover. I tried to remove and could not do it so.... ... I removed old fittings (they are just pressed in), sawed off old boss and had them welded closed, and had a new set of "bungs" welded on. Then I filed flat and had them powder coated. I plan on using union with 90 degree elbow on hose running to catch can, but you could use "T" and link them back to original config.

Not much room if you ever want to remove rocker cover. I tried to remove and could not do it so.... . I used Australian made engine mounts and have exactly the same issue. Never thought to do what you have done, well done. I have modified the bonnet catch (with a hammer) which was far too crude Quote Link to comment Share on other sites More sharing options...
EF Ian Posted December 22, 2013 Share Posted December 22, 2013 Gmac - What size of fittings did you use? I'm trying to decide between -10 and -12 Quote Link to comment Share on other sites More sharing options...
stony Posted December 27, 2013 Share Posted December 27, 2013 I used -12 on mine. -10 or even -8 would have been plenty. All i did was drill and tap the existing holes in the valve cover. welding a bung in is the other way to do it. Quote Link to comment Share on other sites More sharing options...
EF Ian Posted December 27, 2013 Share Posted December 27, 2013 Think I'll go for -10 then. Unlike you I still have the original bonnet catch in place and with my mounts mounting it lower and further back than yours the stock fittings on the intake side cam cover hit it. I'm planning to remove the original fitting, weld it up and weld a -10 fitting just In front of it. Quote Link to comment Share on other sites More sharing options...
ZT-R Posted January 1, 2014 Share Posted January 1, 2014 I used 12s on mine. I tapped the original to NTP. Im running a RB30 block so I had to notch my hood for them to fit. haha Quote Link to comment Share on other sites More sharing options...
gmac708 Posted January 4, 2014 Share Posted January 4, 2014 (edited) I used -12 bungs. I think the -12 is a little overkill. Edited January 4, 2014 by gmac708 Quote Link to comment Share on other sites More sharing options...
EF Ian Posted January 4, 2014 Share Posted January 4, 2014 I've ordered -10 bungs, I hope its big enough, I've seen quite a few setups running this size so the airflow should be enough. Quote Link to comment Share on other sites More sharing options...
Coolwhip Posted February 7, 2014 Share Posted February 7, 2014 To prevent having to weld bungs to the valve cover we do make press-in fittings:http://www.rawbrokerage.com/raw-brokerage-10am-valve-cover-press-in-fittings-rb26/ Quote Link to comment Share on other sites More sharing options...

///M3 & Z Posted February 16, 2014 Share Posted February 16, 2014 To prevent having to weld bungs to the valve cover we do make press-in fittings: http://www.rawbroker...-fittings-rb26/ awesome definantly going to buy a set of these. How do i get the original breather metal fittings out from the RB26 cam covers ? at first I tried using a punch and they didn't really move, then I used a slide hammer and they came right out!
