Hey guys just had my rb30 bottom end freshened up 2 weeks ago, it's all run-in now with fresh penrite hpr10 (15w50) now the issue is oil pushing into my catch can when boosting/high rpm. I have a 1.5mm restrictor in the block & the back one blocked off.

I had my catch can draining back to the sump with the 2 the rocket cover lines going into the catch can & another line going to the turbo intake with a 3mm restrictor, when I had this set up it was blowing ashit load of smoke so I've not blocked the line off to the turbo into & run the catch can oil drain into a bottle to catch any excess oil but it's pushing it out hard & making a oily mess.

Anyone have any idea what's going on?

Done a comp test & it's all within 130-150PSI

2 rocket covers go to the top of the catch can, then I have 1 on the side towards the top going to the turbo intake pipe. Drain I have a fitting on the sump.

Previously before the freshen up I had it T into the turbo return line on the block & wasn't having this issue

      Update time!  The JZX110 had some maintenance needing to be done, so a lot of the seals with replaced to fix some oil leaks. Also used this opportunity to whack on a front mount that I'd bought some time ago.  I also finally got the rear lip painted and fitted.  I then got the exhaust done. It's just a catback for now. Custom made 3" stainless with a turn down. I could have a tip coming out, but it will require cutting the rear lip and possibly the bumper itself. So far I do like and it's made the car a little more zippy.  Close out with some nice pictures of the cars and a sneak peek of what's next.

      This lady loved her FD for 25 years!  https://www.topspeed.com/80-year-old-woman-donates-fd-rx-7-mazda/ My brother in law. He's nice enough to let me drive it whenever. He'll likely not see this, but I'll try: @r-is-for-fun got any pics?

      Just something I found searching for more info on Emotion R, apparently the ECR33 Skyline GTS25t was either originally black, or there were two of them, the black one being the original demo car, then building a white one which was part of the 1997-onwards (to at least 2008!) Cockpit Tatebayashi Tokyo Auto Salon booth demo cars. It appears that Emotion R closed down in 2008 and was declared bankrupt in 2010: http://bank-db.com/hasan/208365. Scan of a magazine with the black R33 from 1996: Wayback machine archived page from May, 2000: https://web.archive.org/web/20000529061027/http://www.emotion-r.co.jp/skyline.html Option magazine with a few photos from the Cockpit Tatebayashi booth at the Auto Salon from various years: 2002: http://www.jdm-option.com/photo/index.php?action=item&category_id=154&image_id=3507 2003: http://www.jdm-option.com/photo/index.php?action=item&category_id=137&image_id=3033 2005: http://www.jdm-option.com/photo/index.php?action=item&category_id=116&image_id=1831 In 2008 Cusco website mentions that the Cockpit Tatebayashi ECR33 was displayed at that year's Tokyo Auto Salon: https://www.cusco.co.jp/event/2008/12/post_735.html As of 2021 it appears that the ECR33 demo car ended up being exported to Florida, USA: https://rmcmiami.com/inventory/1996-nissan-skyline-r33-cockpit-tatebayashi-demo-car-big-te06-turbo-endless-brakes-lsd-450hp/ And finally here's Google streetview of the Emorion R garage in 2023 which is amazingly not only still there, but the showroom is still full of various parts in stock and funishings, etc.: https://maps.app.goo.gl/ttyEAZdZLyzermyT9 Apologies for nerding out a bit. I used to love doing this 20 years ago on SAU and got a bit nostalgic for a moment... 😅
