Mate no need to use special seals. I have built several dry sump RB26's with my own dry sump kit and run them for several years now on track cars with no issues the only time you will have an issue is if you try and run to much vacume. I have not seen any dry sumped GTR's run vacume regulators on them and have not run one on my own car to date but plan on fitting one soon. From all of the research i have done and spoken to several race engineers around 12 inches of vacume is about the ideal amount to run for power production before you will have any problems with seals.

The last one is how its spelt. Vacuum.

I had heard it wasnt till around 18-20inhg where you need seals and forced pin oiling. But that came from an ex toll racing cnc machinist, so who knows if its accurate. I think most supercars run around the 20inhg.

      What should I do next to hold the head on

      By Gareth87 · Posted

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
