Hi all,

I've got an Aeroflow Rose jointed alternator bracket which has been great and works perfectly.

Recently, It started rattling at approx 3200 rpm. it's a really loud Buzzing rattle confirmed with an automotive stethoscope. Its also visual if you rev and hold it around the right revs.

I've tried everything I can think of including swapping the bolts for a shank bolt so there is no thread inside the rose joint. I'm out of options.. Any ideas?

(yes, the photo shows the lock nuts loose. I was in the process of removing it when I took the pic)

Thanks.

Is it really between the bolt and the hole, or is it in the joint itself?

I dont think so.. i just wanted to cross off everything possible.

Rose joints rattle, and then they wear and rattle more. Seems like a strange way to support something with engine harmonics

Yeah i suppose so.. any other ideas. Wonder if a nylon end of some kind would be possible

      RB26DETT Sketchy boost mod?

      I might be way off the mark here.. there must be a T junction under the manifold. That takes manifold pressure through a check valve prior to the T, one side splits out to this bleed off orifice, the other straight to the wastegate actuators.

      RB26DETT Sketchy boost mod?

      By ARB26 · Posted

      Carrying out some engine due diligence before my first drive in a 260RS that has been in storage for 10+ years, and found two lines that are susposed to be plumbed into the boost control solenoid. One of the lines (the wastegate boost supply line) to actuate the gates, had a bolt in one end blocking it. The other line (main boost signal line) from the very rear of the intake manifold (RB26DETT) and runs up to the boost controller had this pill in the end of it as seen in photos. Other than the obvious (T28 Ceramic turbos might well be cooked)  Can anyone shed any light on if there is any validity at all with this mod, bleeding a constant fixed rate of manifold boost pressure off through this 3mm hole?  Is it deliberate?  Was this a 90s Jap mod done to RB26's? Or has someone just fitted this without any idea of what happens to ceramic T28s if they are not gate controlled?

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
