Hey all just checking when i start the car and while its still cold i hear a ticking sound which i have been told can be lifters or can be injectors. How can you differentiate between the two??? just curious. Oh the ticking noise goes once car is warm.

Hey all just checking when i start the car and while its still cold i hear a ticking sound which i have been told can be lifters or can be injectors. How can you differentiate between the two??? just curious. Oh the ticking noise goes once car is warm.

if it goes away when it warm its more likely to be a lifter noise

Aww ok then. So yeah is replacement of the lifters the way to go. Ive gone through the website and searched and tried the remedies such as try all different types of oils hasnt worked,tried using a lifter free solution not worked. what else can be done.

My girlfriends VN commodore had it shocking! Was so loud and didnt go away.

I bought HPR50 oil and lifter treatment, let it run for 10min then took it for a drive to get the oil pressure up.

It went away within 10min of drivin and havnt heard it since.

If you havnt tried heavy oil try that but if you have just get em fixed.

what lifter treatment you use?? Was it the nulon stuff?? My mechanic used it and still does it when car is cold. at the moment the car is stock standard but thinking of doing some mods is it still ok to do or should i fix it up firstly??

Yes the Nulon stuff but it was the heavy oil that did it... I tried the lifter treatment with the old oil and it didnt work then drained old oil and put the HPR50 in it with Nulon lifter treatment. It then went away after a little while and havnt heard it since.

If u try the heavy oil and it goes away then i would reccomment putting lighter oil back in it... the heavier oil just frees the lifter up.

It should be ok to do the mods to your car (especially if the ticking goes away when warm) but I personally wouldnt only cause i am a neat freak and have to have everything running nicely.

easiest way to tell is this. put your head in the engine bay. rev the engine (using your hand on the throttle), let it go sharply. as you do (and the revs start to fall) if the noise goes dead silent, then kicks back in once the revs reach idle then it's injectors (as they all shut off for a split second).

I have the same problem, except the fact mine persists throughout the drive.

It'd been going on for ages and its so freaking annoying. I have used all types of oils and treatments and nothing works, i bought new lifters and have yet to have them installed. Yet my mechanic thinks it's injectors now, after i found out my last mechanic had not tightened my exhuast manifold, and the gasket perished...so half the ticking noise was that.

Solution: Buying a new head, and putting all the new shit in it outside of the current engine, and a simple replacement. Sick of trouble shooting feckin head issues, this noise has pissed me off. Almost pushed me to selling >.<

Good luck with yours, by the sounds of it you need some thicker oil dude. Lifter treatment thins the oil out more to unclog them, and i doubt thats your problem. Thicker oil and you'll be sweet.

Well i used HPR50 which seemed to work... And remember this is to free up the lifter. If it works then drain the HPR50 then put lighter oil back in. If it doesnt work then still drain it and put lighter oil in.

    • I read this and thought "ah! I will do this scissor jack on the tow point thing!" I just use my floor/low profile/costco jack and lift the car up by the tow hook itself, then slide jack stands under. Never thought about using scissor into floor jack combo :p
    • Well, my new WMI system took much longer to finalize. I actually missed my dyno appointment last Friday and lost my 150$ deposit. I'll be going back in the next week or two.  To sum it up. I only kept the AEM tank from my old setup. I replaced the AEM pump with a higher flow/pressure ProMeth 30GPH pump. I also swapped over to a 6AN low pressure feed line to the pump from the tank. There's also a pressure switch you cannot see on the pump high pressure line.    This is feeding 6x 200CC direct port nozzles and 1x 500CC Pre Throttle body nozzle. All fittings are Swagelok, because well why not. I also have a 300PSI pressure sensor up front.    I now have my Haltech ECU controlling everything. I start my pump with a basic relay at 5PSI and deadhead it. I then PWM a 3000CC methanol Injector to control flow starting around 10psi. The pressure switch in the trunk, along with my tank level are safeties before I ever get to 10PSI, and then I use my pressure sensor upfront as a secondary safety to cut the WMI and corrections in case the injector blocks or a line ruptures.  Wish me luck on the dyno!    
    • So, I'm back with bad news. There's no jack long enough on this planet that will reach the front subframe. If by some chance there is, it would weigh 200lb's.  I purchased a long reach jack... The damn thing weighted 120lb's and was massive. Didn't even come close, was still short at least a foot. It was a pain, but I brought it back. Next I decided HA! No problem, I'll get an Extra long reach jack. Well, I couldn't lift the box... It must have weighed 160LB's and luckily there was an open box in store. I took measurement and was still nowhere close.  Sadly I've lost hope and have accepted defeat. 
    • Thanks for that tip, niZmO_Man. I think the battery is OK. It's quite a new one, but I'll check. Last time I needed a new battery, everything electronic was fine, except that there wasn't enough current to turn over the starter. I decided to order one of the partial AV system translation CDs from Car Audio Workshop in NZ. That might have some effect, or help me diagnose the date problem. 🤞
    • I suppose it was relatively stock too, the JZ motor handle most mods thrown at them without even breaking a sweat
