I Have A Ticking Noise? Help Please

[AMS]

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!

EDIT:

Ok it seems it has been brought up numerous times

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?

It drpends on the type of stainless and the type of steel.

You would have to get the specs on both toanswer that.

Tappets?

[qikstagea]

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.
