RB26 Coolant Leak

Noticed temp getting near 100c so I shut down. Noticed a leak. After cooling I filled it up and squeezed pipes and found where its coming from. Anyone know the part number by chance? When I do squeeze it comes out the back of the metal pipe. It squirts straight so its a decent hole and not from the hose being loose. Its at the back of the block next to the firewall. Any help is greatly appreciated. -Dave

well done to have a keen eye on the gauge, lots of people don't notice until it's too late.

while those hoses seem to often be the first ones to go, everything will be a bit old and brittle by now.  why not do a full hose replacement kit like this one for fun over the break, or even better give the car and kit to a mechanic in january :) http://justjap.com/jjr-silicone-engine-heater-hose-set-nissan-rb26dett-r32-gtr-blue.html

I will get the kit I found on the japan yahoo auctions and probably do what I can. I have access to a lift(hoist) and many tools. Definitely going to get a new radiator as mine is pretty rusty looking on the inside. I should've swapped it when I got the car. Wish I had the extra cash to drop it off somewhere. Bet this job will be a pain.

How do I remove 14498-05U14 please? I dug through the manual but didn't find anything. Do I start by removing the bolts on this end(in attached image)? Kind of lost since I was unable to source the replacement yet but would at least like to do the first part while I wait. I am going to use Amayama since no shops in Japan could get it for me. Thank you!

Yes they do screw right off, but they can also seize over time and when they do they can twist until they break instead of undoing.

Try a little wd40 over a couple of days, and use a flare nut spanner if you can.

But odds are it's going to break and you'll need to replace it.

      braided lines for the turbos

      By GTSBoy · Posted

      For your application, where you'll be at that 1/2" size or perhaps larger, yeah, excellent. Although not if you need a tight bending radius anywhere, because the corrugated stuff is not anywhere near as flexible as rubber/teflon cored stuff. But for turbo oil lines? No. Too big. They just don't do the corro stuff down at the ~1/4" ID size that you'd want, and if they did the OD of it would probably be a bit too fat for fitting it into the tight spaces available. I use hoses like that all the time for fuel gases (LPG, NG) and liquid fuels (HFO, diesels, waste oils). When we did the London Olympic cauldron, with the 204 individual burners on it, we had miles of the stuff (although a lot of that was teflon core). A bunch of that crap is still cluttering up the workshop, more than 2 years later!

      Would something like this be an option  https://processhose.com/products/configurable-metal-hoses/1-2-in-t316-stainless-steel-annular-corrugated-configurable-flexible-metal-hose-assembly-with-ends-t304-single-braid-masterflex-af5550.html I'm looking at this for replacing the OEM EGR when installing a aftermarket intake plenum

      The once piece tail shafts with cv type joints on either end are the ones that end up vibrating and the vibration is caused by the cv joint binding as it turns, I’ve also seen them explode from the binding

      Take this with a pinch of salt, it's from someone (me) who got annoyed with turbos entirely. I hated aftermarket lines. If I had the option to use hardlines with whatever turbo I had - I would use them, 10/10, 100% of the time. The only reason people go larger, heat resistent, shielded lines etc is because they have to. And yes they don't last forever. Even if you spend big bucks on all the best heat shielding money can buy, with the best heat resistant, fuel resistant, oil resistant, radiation resistant hose, they get stiff and break down and just don't last the way a metal pipe will.

      Unfortunately I am quite literally halfway across the globe. So all sources for parts like that are far away for me. What do you mean by that exactly?
