Yeah it is annoying....

Just wanna make sure that something isn't broken or about to break...

yea same here, im going to get the HKS exhaust looked at, it hasnt been touched since it was done in japan, before the i got the car. so not sure. well see if it solves the ticking. might pull it all off and change all the seals/gaskets.

Let me know how you go as my exhaust is HKS as well and I don't think it has been off the car since import

Be nice if it is that simple

Had a similar thing with my old RB20 - I thought it was a sticky lifter, but after I sold it, the buyer advised me that he had pulled it down and there was evidence of piston-slap.

Another possibility, since the noise seems more pronounced on the underside, is a dying / shot big-end bearing.

its definently not either of those things. ive built a few engines, and ive heard these noises before even from engine ive owned had to rebuilt cuase of it, the 'Ticking noise" from the sky, is not a KNOCKING.

its a little Ticking. like a switch or something. or when u flick ur light switch.

Yeah id say lifters. My car does the exact same thing its like tick tick tick tick tick tick... in quick succession., i was a a bit worried when i first bought the car, but then figured out what it was. Nothing major.

Just a quick question, how would an exhuast leak make a ticking noise evident from the engine bay?

ummmm.... injectors!!!!

if your talking about a silent ticking sound that sounds like clock work exactly in beat.... its your injectors.... perfectly normal!!!

a loud ticking/taping sound that comes and goes (louder when engine is cold) thats your lifters.

my R31 (RB30ET) has loud lifters the whole time Iv had it (7 years now) - they tap litteraly when they feel like it, never changed them, never were a problem anyways!!

From what everyone is describing - its ya injectors!! :rolleyes:

and dont stress - they're supposed to do that!

tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick..................

it sounds more louder from under the car, but this could be noise rebound. still getting exhuast done, will let u guys know if it did anything :rolleyes:

and yea i thought could be injectors also. we will soon see.

Hey dale im having the exact same problem as u described, it comes from underneath the engine, its definitely not a lifter or a knock in the bottom end.

Did you end up finding what it was?? Will be much appreciated :thumbsup: BTW sorry about the dig up

Talk about digging up old threads.

Sorry for the late reply.. Welcome back to June i guess.

Now about the ticking noise.. Really depends on the noise itself, its definently hard to say our noises are the same.. but for me it is related to the injectors. But why infact is interesting, some people have gotten it from different reasons, but mainly to do with exhaust changes, bumps, or air leaks.

I have brand new Nismo Triple 5's, and mine made no noise till my exhuast scraped a speed hump, coinsidence? perhaps.. however nothing is actually a miss- or broken, so it not broken? dont fix it.. lol

cheers.

I also have the same noise just on startup from the tappets and my understanding is that oil drips into the sump overnight and when you start the car, the oil pump pulls oil back through the head, hence needing to drive like a granny for the first 5mins and not flog it til it's warm.

Or something like that :)

I'm Having the same problem, although ive managed to pinpoint it slightly, if looking at the car from the front the sound is coming from the right hand side of the engine, at the back, close to the firewall, kinda just above where i can see my o2 sensor plug, its a consistent tick tick tick tick tick, jsut like a clock thats a little fast, and it does also seem to go away when engine ahs done some work, but eventually comes back.

what i didnt think to try, was holding the rpm higher then 650-700 and check if the sound recedes, but i'll give it a go when i get home.

a friend of mine said it was defs lifters, and not to worry, but after reading this thread, it makes me want to double check my diagnosis, also, if it is the injectors, does anyone think that an injector bath would help/solve the problem, and or, has anyone actually got results from the injector bath?

oh and by the way, big end bearing noise and lower end tap is incredibly hard to mistake for a ticking, its more like rapping your knuckles on metal, or a clacking sound like some angry kid with a pair of chopsticks being a noisy bugger, ive seen cases of piston slap on smaller engines, and they make quite the distinctive sound, even if your born blind, deaf and daft, you cant miss it, maybe the daft one might, but you get my point.

im quite nooby when it comes to RB's, i know the basics like oil/filters etc, but ive never had the top off of my neo6, so i have no idea where even the plugs are!

good advice everyone btw, so helpful, and no flaming, wtf? is this a forum with real people on it? :blink:

      Baron's R34 GT-R build thread - car in Japan for 5 years -_-

      By soviet_merlin · Posted

      I'd be curious to hear more. Otherwise, have you driven a modern x-trail? I wonder how it compares. Here in Australia they are/were popular for rentals and fleet vehicles. I have been in some and my impression was they are bad. But, this may have been very different in the 2000s at a good trim level. Twenty years is plenty of time to make the model worse. I do very much agree with the 2 silver cars in the garage approach. But, not driving because it's too hot would not leave a lot of time in the year for many Australians. I don't think you need to worry too much unless the car has actual issues with overheating.

      Baron's R34 GT-R build thread - car in Japan for 5 years -_-

      Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.

      Thanks for that, hadn’t used my brain enough to think about that.

      Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.
