Not sure if anyone has said this yet... But have you taken a look at the solenoid? Mine was doing that about 5 days back... I real loud ticking, I was left wondering what the hell it was - so i adjusted the IEBC a little an it was gone. But yeah the solenoid makes a very loud ticking!

wot solenoid?

the boost solenoid

wtf is that? And why wood it fu after a plug and oil change.??

remember i'm talkin bout a 13.

Sounds like something (and I don't know what) was stuck and after the extra additive was freed, might have just been a coincidence though and could have come good on it's own... Keep thrashing it and I'm sure it will come back sooner or later then you'll know for sure! :) Sounds like it is internal though, close to impossible to diagnose at this point.

As for the Manifold nuts going missing (mentioned a couple of months back sorry) the nuts are stainless steel and they use them so they don't seize on themanifold, so you can get it off without snapping all the studs off. Down side is that they can come loose and even fall off after a while so that is probably the explanation for missing nuts on various manifolds... Mine were loose on the turbo manifold and were causing an exhaust leak that was a scream at higher rpm but it developed into a leak at lower and lower rpm as time passed, tightened the nuts and all fixed.

Don't know enough about the S13 Turbo system to comment on the boost solenoid, you have one on the Stagea though, check out the boost control thread in the DIY's for more info. Basically 2 satge boost is standard on the RB25DET.

Thanks for that Luke.

With the S.S nuts ,the S.S has a greater rate of thermal expanstionthansteel.After heating and coling many hundreds of times they start to work loose,

No worries,

Does being S.S make them softer too?

sure its not your fuel injectors mate? i know mine are noisy. was curious about the clicking myself, had a good listen, sourced it to the fuel rail, and there you go.

(tappets in an overhead cam engine...? eh?)

and stainless steel is harder, but more brittle. The softer steel bolts are more maleable, would screw in and the thread would move slightly as you tighten, to form a really tight snug fit to whatever youre screwing it into.

stainless, being harder, doesnt do this as much. being harder and less maleable lowers the risk of shearing the head off when you undo it after 10 years, but means that it doesnt sit quite as snug, and can rattle out.

this is also why stainless steel exhausts can crack after a few years, but sound better.

    • Yes to both! Yes to standard ECU and tune, but exhaust is aftermarket. Unsure on brand. Actually have it sitting in at my desk haha! I have to set it up on my laptop but this is a great next step, will do. So I generally try to shift before 4.5K RPM most times. I largely don't do a lot of high-rev driving, but I will take it up to red 1-2x a week max, as I know the occasional "Italian tune-up" is good for these cars.  Oh wow, is this way better than what I'm getting. Does this mean there's a good chance I have an issue?   Thanks for all the info so far guys.
    • Old Son, did you re-use the Holden ABS in the new shell or try a different module?
    • Yeah, nah. I had the actuator rod off it today. The arm will not move at all. Neither out, nor in. Yeah, you'd think so, but I've been thinking about that. Even when the actuator rod fell all the way off at the beginning of this saga, it would build more boost and faster in lower gears than it would in higher gears, and you'd think that that was the opposite of what should happen. But I strongly suspect that there is a thing with the gearing getting the revs to rise faster, that there must be some transient effect with the gas flow rate rising quickly, that you don't get with the more steady state case of the higher gears. Keep in mind - the gate is not shut in either of my weirdnesses. So things are not "normal". We normally think about a turbo spooling up (below the wastegate target) with the gate shut. I have all sorts of mental models running now where the gate is a little bit open, and having it stuck open allowing gas out while it should be going through the turbine has all sorts of weird effects (in these mental models). I'm thinking in the higher gears, the ex mani pressure builds to the point where enough gases spill out the wastegate to just prevent the pressure rising much more at all, or just creeping up, all the whole the revs are increasing and getting closer to the point where a gear shift becomes necessary.
    • Is it possibly wastegate actuator itself is sticking, or even the rod to flapper? Otherwise I reckon things are getting a bit rusty/worn   Also odd it won't boost in 3rd to 5th, but will in 1st, I'd expect the other way around with it slightly open as there's more time on your way to redline for it to spin up
    • Does anyone know ow what these two plugs are for and if they should be unplugged? Just put the dash back together and can't remember if these were plugged in before or unplugged! (Blue and white plugs) 🤦🏽‍♂️
