  1. I can't tell by your photo's exactly what portions of your rails are damaged but I just checked and Nissan actually still produces at a fair price most of the rail. Cheers.
  2. I really like it. If there's any part of it that I'm not 100% on; it's the rear.
  3. Welcome! I'm also from Canada and I get all my parts directly from the dealer. Nissan Canada can get anything directly from Nissan Japan, and some times weirdly enough has it in stock (Ex. My R32 skyline rear interior trims they had in stock at the Montreal warehouse) It's also always cheaper then you will find online. Cheers.
  4. Nissan calls them recirculation valves, and this being a Nissan forum I'll stick with that but their patents have a variety of different names. Speaking of patents, they also describe their purpose. Here's a portion of text of one of hundreds of different patents. Cheers. Patent US10077709 FIELD OF THE INVENTION The present invention relates to diverter valve systems used with turbocharged or supercharged motor vehicles. BACKGROUND OF THE INVENTION Most modern turbocharged vehicle engines include some form of factory-fitted blow-off or bypass valve in the intake tract, the purpose of which is to open during throttle closure to provide a relief path from a diversion aperture or pressurised air that would otherwise cause significant pressure spikes, resulting in damage or reduced life-span of the turbocharger, and also an unpleasant fluttering noise that is deemed unacceptable in a road-going passenger car. There is also a potential performance improvement, in that without a relief path, rapid throttle closure and the resulting pressure spike can rapidly slow the turbo compressor, leading to a longer delay in returning to peak boost when the throttle is re-opened (i.e. increased turbo lag). Similarly, allowing the bypass valve to relieve too much pressure can also have an adverse effect on turbo lag—evacuating the entire volume of the intake tract means that despite maintaining a higher compressor speed over the short term, when the throttle is re-opened the intake tract must be re-pressurised which causes an increase in lag.
  5. I highly doubt every automotive manufacturer is designing and adding parts (Recirculation Valves) which cost them extra money and complexity just for the fun of it. Same applies for Turbo manufacturers recommending them when they don't even sell them (Garrett, etc.)
  6. Just drive it slow and out of boost on your way to the dyno.
  7. Blown turbo doesn't automatically mean his turbine wheel grenaded. Now with that said, the difference you have in compression between cylinders isn't great. Report back on a warm engine.
  8. Anytime I purchase a "new" used car, first thing I do is change all fluids. When in doubt, change it.
  9. Your issue is not the oil drain, it's the fact that you basically sealed up your engine. I'm blown away you have not been sending dip sticks to the moon every time you start your car lol. Do not start the car back up like that. If you want to keep your hoses setup the same way, replace your sealed air/oil seperator with a vented catch can (The ones with a filter on top). I prefer running an oem type setup with 2x sealed air/oil seperators.
  10. is that catch can sealed? If so, that is not at all how that should be done and will cause damage.
  11. Another thing that will cause this is a seized alternator, ac compressor or p/s pump. It will make the engine turn over much slower causing it not to start. I see this often on Suzuki's with seized alternators.
  12. That's far from a right off. You're good to go.
  13. Go pull your hose, drive around and let me know if "all the boost will bleed off." Cheers.
