Hey guys, recently purchased myself a series 2 Stagea RB25DET Neo and the other day taking it on a long drive and after arriving home i could hear a almost knocking noise from the engine (barley noticeable but bad enough to make me concerned) so i popped the hood and had a listen.- the noise is worse when hot, cant be heard off of idle, isn't hearable at idle when cold and using the screw driver trick the noise can be hear from the front (near runners 1,2) of the intake manifold but the noise can also be heard from the RH rear rocker cover... Just wondering if anyone has had any similar experiences.

Thinking it could be one of the rear cam/shim clearance.-noise at the back of the rocker cover makes me think that.

Any advice/experiences would be greatly appreciated.

Some photos of the Joy.

Firstly, congratulations on your purchase and welcome to SAU.

Is it only audible with the engine off and after a long drive, when the engine has had a chance to reach full operating temps? If it's a ticking noise with the engine off, it's most likely only the regular sound of the engine cooling down.

Because there are different metals used for different parts of the engine, they all cool at different rates, and the stretching and contracting of those metals at different rates is what causes that noise.

Thanks mate.

Nah i know that noise, the noise Im hearing is always at idle when hot and its more of a knock then a tick (sorry about the title description).

Yeah looking forward too a couple of Stagea cruises.

and too take some more photos.

noise from the intake would more than likley be injector tap or worse an air leak (you would notice sh***y running though), my s1 injectors are quite loud but they have been reco'd, use you screwdriver trick on the injectors and you will see what im talking about, to listen for an air leak, i use a piece of vacum hose stuck in my ear one end and point it around the intake gasket you will be suprised at what you can hear doing this, the noise at the back of the tapper cover could be a sticky lifter maybe, run some nulon lifter free through it next oil change and see how it goes!!

Cheers for the input fellas. Okay so today i grabbed some of that Wynns engine flush and put it in the car and then drove the car to trade school ( wynns man said it was okay to leave it in over night). Got too trade school noise was still there a couple of the blokes had a listen and said bottom end. But bottom end is more under load and higher up in revs. So after trade school i drove it too work (I'm an apprentice mechanic)-And let the other mechanics have a listen all of them couldn't distinguish where or what it was possibly shims/lifters. (unsure if series 2 are hydraulic or not).

But the noise is that quite when they were trying to listen too it they said don't worry about it and wait a little bit and see if it gets worse.

So i drained the engine oil etc. ran it again, drained it again. Put some 10w40 in and started her up, drove the car home and the noise was still there.

So im at the point where i am waiting and hoping that it doesn't get worse. (and ill be keeping a close ear out for any change what so ever)

Thanks again.

My previous s2 used to make a faint knocking noise when idling. Wasn't loud or anything and didn't sound that bad. It never got any worse so I never did anything about it. Pretty sure I was told it was likely the lifters...so my guess is that its fairly normal on the NEO engines.

I owned the car for 2 years and never had any issues from the engine. The RB25's are pretty solid. Not the smoothest idle i've heard but it was always a strong performer. :D

RB engines can smooth idle.Ghostrider sent me a pic of his 1UZ Cressida that had a 50c piece standing up with motor running. LOL. I sent a pic back of my S1 with the 50c standing, so they can idle smooth. I must admit though that had just give it a major service and changed all the belts.

On the S2, at the back of the tappet cover is a polution control solenoid. It tickers away at idle and goes away as soon as you put some revs in.

Mazda V6's used to have the same problem and the factory solution was to rubber mount the solenoid.

Either way, the NEO is a solid motor, thrash it till blows!

Yeah come to the dyno day.... So you can meet some of the SA stag crew and chuck it on the rollers to see if its running as it should and then you will have a base figure before mods :happy:

Looking forward to catching up with you all.

      So.... the K&N air box thingo was too big, ended up gifting it to a mate, well, by gifting it he actually supplied food and beer at the pub,  which was nice, as it will not sit on a shelf in the garage for the next 10 years I did trim up some of the existing stuff to neaten it all up and gave it some wrinkle paint, unfortunately it currently has a used and abused mish mash of different types of hose clamps, 4 big fat T bolt type (shit), and a few normal clamps of vairing sizes and brands, but..... only until the 6 constant tension black worm clamps that I ordered from EFI solutions turn up next week Currently the current hose clamps are triggering me hard, LOL Is this the final version, probably not, I really want just 2 silicone pieces, a straight bit of silicone from the filter to the MAF is easy and will happen as soon as I head into Just Jap tomorrow, the problematic part is a 30° silicone bend from the MAF to the TB that I can connect the engine breather from the head, I found that there are bulk head fittings for boat bilge pumps that should work, but until I can get a 30° silicone bend the alloy pipe, and the 11ty thousand hose clamps, are there for the foreseeable future 4 hose clamps are golden, 6 are grudgingly acceptable, the 8 currently holding it all together is just taking the piss    I've also ordered 60 more retaining wall blocks for the front yard, I mis-gonculated the height that was required to get above the base of the Photinia's (red robin's) that are the hedge behind the front fence, currently it is 2 blocks high, and about 1/2 a block short, so going 3 blocks high will be above the base of the red robin's, and allow some room for mulch

      It is the stock air box with the panel filter. Everything else is stock except the exhaust at this point, as I also went back to the cleaned 270cc injectors. I will check the RPM when the IACV is unplugged and report back.

      As MBS suggested if this is happening when the engine is cold you're going to want to remove the intake air regulator and verify resistance + that the shutter is physically opening and closing. At -20C should be fully open, 20C half open, over 60C fully closed. At 20C should be 70-80 ohms. For AAC valve testing using a Consult cable see if you can raise and lower the idle by commanding more or less AAC duty cycle. Hopefully it's pretty linear as well, shouldn't be like 30% AAC valve is barely idling and 40% is 1500 rpm.

      Not sure yet.  Was considering speedtek because it was rated to 800hp, but when I did some research about him I don't think I will go for that🤣 So maybe giken gear set, but I'm afraid it won't be strong enough🙄
