Hi everyone, I'm currently in the process of building my RB25 Neo. I've read the entire oil control thread and have been implementing all the recommendations. I'm wanting to enlarge the 5 oil return holes in the head and block from 8 mm to ~9-10 mm. I found when aligning the headgasket using the dowels to the underside of the head, that the 5 oil return holes line up perfectly. It's just a matter of opening up the existing holes. Not too difficult. However, when sitting the headgasket (again aligned with the dowels) on to the block the 5 oil returns are all completely off centre (see picture below). If I were to enlarge the exisiting holes much more, they would protrude under the gasket. I have a spare R33 RB25 block, and it's the same thing. I also check using the original headgasket and it's the same. I thought the idea was to align the drill with the existing hole (on a mill or I've even read people doing it by hand) and enlarge it to 10mm to match the headgasket. Am I missing something? Any help or info would be super appreciated! 🙂

Broken Fuel Rail Bolt - Help Me, I'm F**ked! Hey SAU. So as part of my ever running saga of crap I have to deal with on my R33, some of you may know from my build thread that I broke one of the 3 fuel rail bolts. This likely happened from me over-tightening then a few jolts from some spirited tuning runs was enough to vibrate the head off the bolt. Sigh. Anywho, I set about pulling off the intake manifold today (what a b!tch!) so I could get an "easy out" on the bolt. Well, even as difficult as that was, things are now made even worse by the fact the "easy out" decided to break off in the bolt. FuuuuuuuuuuuuuuUUUUUUuuuuuu... I was even going easy on it..... So, to the point, I am absolutely struggling to drill through this bolt. I think there's a tiny bit of the "easy out" left in the bolt, but it mustn't be much. I've been drilling it with 2 different drill bits, one a "Heat Treated Tensile Bit" and the other a "Cobalt HSS" bit by Sutton Tools. I've been drilling for over an hour and getting seemingly nowhere Has anyone experienced this or something like it? Does anyone have advice on what I should do? Is there a mobile specialist that could take care of this f**king bolt for me? Any help appreciated. Thanks bros.
