Hi all,

I changed my radiator hoses and coolant today. I was shocked. Seems the part where I attach the hose has rusted through. Any fix for this? (I've included some pics.)

Urgently need some help.

RB25DE - Non turbo

Cheers

Wow, that's not good.

Would say you engine hasn't been running any inhibitor in the coolant system. This stops corrosion of the metal and alloy parts throughout the system. Make sure you put some in once you've fix this up.

I would say the the steel tube will need to be cut out of the aluminium intake maifold and a new pipe pressed into place.

I would recomend an engineering workshop or competent mechanic.

oh god

i was hoping to do a coolant flush this weekend

i hope i dont see what ive just seen.

hehe - i was thrown back at the sight.. pretty nasty.

Nissan was quoting $800 for the bottom half of the intake manifold, as it is 1 piece (ordered from Japan - brand new item) they do not supply the tube end.

I probably can go to a machine shop and get a new pipe inserted, but its gonna be a pain taking out the intake manifold, i wonder if they can fix the issue with it still in place,,,,

Could possibly do it in place, but you risk getting metal shavings into the system.

The intake is really too hard to take off. Take the top section off first, then it'll be easier to get at the bolts that hold the lower section to the head.

After much thought and discussion with some mates I've decided to get the exact dimensions of the rusted piece and get a custom piece made up.

I'll then chisel out the rusted piece and press fit the new custom piece.

I wonder if stainless steel would be a good idea or not - I mean would it cause a bad reaction with the coolant etc?

I've found an engineering place nearby http://www.yann.com.au/

Any thoughts or pre-cautions?

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      By nouveau_poor · Posted

      I certainly fall into the annoyed camp, but glad to hear that if it's happening at low boost then I'm not likely going to blow a turbo and end up with metal shards in my oil. Just feels like it prevents me from really driving it without hesitation and "peak" performance. Wonder if it's the VCAM, it did an impressive job of shifting the torque curve and faster spool, but maybe now it's "too fast" and there's too much air for how open the throttle is.  Based on some other threads, will also do some reading on synchronizing the actuators. They are the default actuators that come on the Garrett's and I would think they would be set the same coming from the factory, but if the turbos don't actually work exactly the same way at the same time as previously mentioned, it would be worth making sure the actuators are actuating together properly

      R34 Skyline Sunroof Won't Tilt/Vent

      I went down this rabbit hole before, ended up sourcing a motor from the UK (I'm in Japan) which also didn't function correctly. With the original motor, I disassembled it and reassembled it and it works somewhat, sometimes. What I could deduce from all my screwing around is that there is calibration of the gears on the inside of the motor and two ramps on the main gear which activate switches that operate the motor and move the sunroof either to retract into the roof or tilt. Where I got stuck was that, it seemed in my case that one or both of the switches that are activated by the ramp on the gear did not always activate and thus the motor did not move, causing it to sometimes not retract or tilt (apologies, I've forgotten which way it didn't work.).  Of course this part is discontinued at Nissan now, it's the same part in the S15 but no other models. I also contacted the manufacturer of the component for schematics - forgot the name, they're based in Gifu - but they declined to share the information due to being bound by an NDA, sadly. Looking through my pictures now, it seems I last had a crack at this in 2022. See, I so kindly wrote "open" and "close" next to the switches. If you figure it out, please do tell me. Those little switches, with the red buttons may need to be replaced.

      It says 300ZX, does that make it an Aus delivered car? Funny how back in the day I just couldn't care less about Z32's and these days I am just in love with them. Back when Nissan was into pushing the envelope. 🤣

      R34 Skyline Sunroof Won't Tilt/Vent

      Hi guys, just after some guidance with an R34 sunroof that has stopped working correctly. It still opens and closes perfectly fine, but it no longer tilts/vents up or down. As a result, the rear of the glass now sags a bit as it drops down slightly in order to retract into the roof, but now it can't pop upwards into a flush position. I’ve probed the pins on the back of the switch connector with a multimeter and it seems like both switches (for open/close and tilt/vent) still work correctly. Any ideas on what it could be, or where I should even start in terms of diagnosing? I'm sure someone's had this issue before but I haven't been able to find anything online relating to this specific issue, most of the issues are with the seals leaking or the motor failing entirely. Thanks in advance!
