Doodz it might be a belt tensioner.Have you recently installed a heavy duty clutch?

definetly not the clutch either.

I would put money on it being a sticky lifter, especially since he changed the oil last week and with a different type :)

My car is doing the same thing and was told it might be the lifters but someone else said its the injectors because its an RB26, dunno which is right but i want that sound not so loud, and its on idle aswell :)

The injectors are always noisy on every skyline i have heard, but on GTRs (especially older ones) the head does get a bit noisy, they dont have hydraulic lifters which when working properly are quiet, the head in a gtr will just be a bit noisy all the time with age

My car isnt THAT old.. its a '94 model (the last year they were made :P ) .. it was coming from the front of the engine/fuel rail ..

if i was to upgrade injectors would it be not so noisy? Because it sort of worries me.

if it does make them quieter, good excuse to upgrade them :)

ok update...

mechanic found two problems that might be causing the noise..

water pump was loose, banging against itself.

and the ac tension bearing pulley was sqeeking

got both parts at justjap $183, but i bargins and got it to 180$ LOL. I think this was SAU price too..

well by old i mean say more than 5 years old <_<

New injectors are quieter, but wont be forever! I wouldnt worry about it, just make sure they are clean and they should be fine, they are all a bit noisy!

dood go and get a long screw driver and listen to ur engine, this happen to all skyline...........so dont worry.......try using motul 8100excess.......and it would go away.....the lifter is tapping the top so it ok...

if u rev ur engine up and it tick,tapping...then it could be ur cam bearing.........

its all about the oil.

what viscosity is the motul oil your using?

25lifters can be very sensitive to changes in iol thickness. the oil feed to the head can also block up :blink:

undo the oil cap and see how much oil is getting up there.:

i spose the easiest way is to chech it with a friend with the same engine

ps. there should be enough oil to splash evry ware with the oil cap off.(just the odd splash out of the oil cap with a continuase swirl of oil around the cam lobes,if thats any help

cheeres

    • Hi 🙋‍♂️. Just bought my Unicorn but the interior need some minor work so it would match my expectations ;). I noticed it is hard to get used oem floor mats in good condition so i started to dig if there's any chance to buy set of new ones. I found two websites - nengun and amayama and it looks like one can still buy factory new floor mats in Japan, but thers a small issue. Some mats (i assume genuine, oem ones) are marked as G4900 and these are "discontinued". The ones you can buy are marked as G4911 but i have no idea if these are also oem, made by other producer or some lower quality replacements that looks entirely different. Can anyone help? 😃  P.s. there is also some strange indication - 0V005, 0V015 and 0V505. Any idea what does it mean? Would appreciate any help with this 🙏
    • Hi, Marek here 🙋‍♂️. I finally fulfilled my longtime dream - recently bought Stagea and now waiting for it to arrive in Poland. There's only few of these in my country, and one of the owners  recommended mi this forum as a source of all the info i'd need since now i own one  so here i am.  
    • Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though
    • and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.  
    • Oh, you are right. But, in Australia E10 is based on 91RON fuel and ends up being 94RON. Hence it being the cheaper option for economy cars. The more performance oriented cars go for the 98RON fuel that has no ethanol mixed in. The only step up we have left then at some petrol stations is E85.
