R34 ticking noise - neo engine

Ok so I'll attach the video I just took and see what you all think it is. It's started probably about a week ago. My 34 currently has 216,000 km on it, fully stock apart from pod filter and boost controller running 12 psi, and yeah it's just an annoying ticking sound. Not super noticeable when driving unless you really listen for it, but when near something parked up, or next to a car, the noise echoes against it, and it's really blood annoying. In the vid just listen for the constant tick noise that goes up with the RPMs. Just trying to figure out what it is, how to fix it, and if it's urgent. So far with a little bit of research on YouTube trying to match the sound, I've found it could be lifters or timing belt pulley/ idler

Can't tell if it's mechanical or an exhaust manifold leak from the video.  Use a hose as a stethoscope to listen around the exhaust manifold and turbo gaskets.  If not there, use same hose, or a screwdriver as stethoscope to listen around cam covers, timing cover, etc, to see if you can localise it.  It could be worn tappets causing valve noise, or it could be your VCT solenoid or belt tensioner up the shit, or a number of other random possibilities.

So just got a screw driver and went on the vct solenoid and all that good stuff, couldn't hear the noise. Went on the right side rocker cover, could hear it, left side slightly but not a lot at all. The closer to the front of the engine I went, the louder it was. The cas was the loudest I could get it. So I'm guessing it's something timing related? Perhaps could be one of the timing pulleys? Not sure if tightening it would do anything though. Another possibility if it's internal, could be oil viscosity maybe? With the KM's its got, I'm running 10W50, did the service last weekend

Taking it off, it needs to be back in the exact same location doesn't it? If it's put back slightly different, what would the outcome be? Would the cams just smack against the rocker cover?

Cams can't smack on the rocker cover.  That's not possible.  They rotate through 360° in there as normal business.  The actual risk of taking the timing arrangement apart and not putting it back together correctly is that you will strike open valves with rising pistons and trash at least part of the motor.  This is not to be contemplated if you do not know how to keep it all together in the right places as you take it apart and put it back together.

I wasn't talking about thoroughly dismantling the timing arrangement though.  Just about pulling the CAS off (and then maybe the upper timing cover too for a better look).  And yes, the CAS needs to go back exactly where it came from, or you need a timing light to be able to reset it.

I recently took the CAS off, marked my timing cover, got the new one, marked that up (It is a clear one), and put it in. The timing belt looked in pretty good condition, so I decided not to change it. The ticking didn't start anywhere near after doing any of that, so couldn't have been that. If I were to take it off, what would I be looking for?

Ok, I took off the CAS. The bearing is making a noise when spinning it. louder than most bearings that I've heard. I took it off, lubricated and cleaned it, and the noise actually stopped for a bit. Then it started up again after about 20 mins of driving. Might try take it off again and properly lubricate it and give it another clean, see if that does anything. Not willing to buy another CAS as they're going for around $800

      It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪

      And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil

      Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.

      Unsolicited advice? Keep the engine as close to stock as you can. Nothing wrong with adding some boost and making a little more power, but given where you are, you really don't want to try to make it into a monster. I can't imagine the roads are up to it, and the lack of locla support when it grenades will be a ball ache. FWIW, If there is a dyno around that you can access, then brand new injectors are a good idea, which will lead you to (at least) putting a Nistune in it, which will allow you to put an R35 AFM on it, all of which will make it possible to make it much much nicer to drive and live with.
