Hi

I was driving my brothers r34 rb25de neo after servicing it and replacing / fixing his dead coilpacks.

Driving the car back after doing a service, at operating temp I noticed it had dropped to zero oil pressure and shut the car off no more than 15-20 seconds later (was driving in heavy traffic in a no stop zone) pushed the car into an alley and parked it.

I noticed a whining/very high frequency tapping/rattle noise from the front quarter of the engine, which sounded like the oil pump, or oil pickup starving, or very early sign of bearing failure. it was NOT a serious bearing rattle as i have experienced this before in different engines of all kinds and its pretty easy to notice.

Noise occurs while engine is at operating temp (or close to it) and not while cold with the thicker oil. oil pressure still shows normal when running, (high on cold, 2.5-3kpi on OT). engine is only at 110k kms.

i have not run the engine since, in the event the bearings are dead.

hoping this gives enough info for somebody to lead me in the right direction in terms of what to check for.

Thanks in advance.

Josh

      S1 Autech 260RS Wiring Diagrams

      By ARB26 · Posted

      Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻
