Freshly rebuilt RB25DET Neo, all done by the one shop except for the machining, so the reassembly/rebuild, bed in on the dyno, and final tune. So far have done just under 1000kms since getting it back, and then this tick started happening.

Was a bit quieter the other day when it started, took it to the shop to have a look, was told it was likely the VCT gear had shit itself because of where the tick was situated, and to take it home, i drove home cautiously and havent driven it since, but started it up today and it was suddenly louder and more rattly. The shop is taking it back later this week to see what the go is, has anyone else had a ticking like this? Sounds like its in the head, the spun bearing it had before getting rebuilt was a deeper knock and definitely down in the bottom if the engine, different to this, its alot higher pitched 

Thanks in advance people!

No, the solenoid is not the actuator. The actuator is on the cam gear, to make it actually move when given oil pressure by the solenoid.

Ah ok so best bet is replace the cam gear? I do have a spare low km engine with one on it. Will try replacing it with that

The actuator is not the cam gear. It is attached to the cam gear. But if you wanted to swap over the whole cam gear, then that would (should, depending on the health of the spare) work too.

Ah understood. I cant find anywhere that sells just the actuator, just the whole unit itself with the gear unfortunately. Not cheap either

      R33 RB25DET oem turbo replacement options

      If you are fine with China turbos, Maxpeedingrods makes a bolt on turbo. Ive had mine for two summers now and it seems to be holding up ok.

      R33 RB25DET oem turbo replacement options

      By KyoyaR33 · Posted

      Howdy all Im in a little predicament and wondering what everyone’s thoughts are? I’ve had my long block rebuilt and am in the market for a turbo due to my old one having metal shavings from crank bearings (cause of rebuild) go throughout the turbos oil lines and there wheel has a little play. I’m not really aiming for any power, just trying to keep it as oem as possible, but I can’t find a turbo that’s built for the stock ecu or find something that would be a standard replacement. Anyone have any ideas or suggestions

      How's everyone going? Just a shout-out introducing myself. I'm James, I live on the north side of Brisbane. I bought an R33 that had been left to rot in someone's front yard for 14 years. Apparently, it has immobiliser/fuel issues. Long story short, it's suffering from a seized engine, plus whatever else turns up once it runs. The car is pretty good considering it sat for so long. It pretty much died after being imported. It has a bunch of Jap parts and a full Top Secret body kit. It's painted Fiat Turchese Festival, or aqua blue if you're not French. Another project to throw money at!

      Is the Clock Spring and Steering angle sensor the same thing?

      By silviaz · Posted

      So the clockspring is responsible for the indicators cancelling on their own? I thought that was the function of that white thing in the center (any idea what it's called?)

      Can you log IAT? Whilst WTA coolers have their place, doing any sort of sustained run is not one of them There are fixes that slow down the heat soak, like ice boxes, which don't last that long, and interchillers, which are fairly expensive, up grades to the WTA cooling radiator, which may require a bigger pump, and upgrades to the reservoir size,  and upgrades to the cooling fans, but, it all still heat soaks, and takes ages to come down in hot weather  For a turbo, that isn't locked into WTA like my PD blower is, can you not possibly swap to a nice air to air intercooler????, it would be better for sustained runs then, and have alot less things that could go wrong in my opinion
