Injector Noise Vs Lifter Noise

[LatinR33]

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.

[LatinR33]

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??

[bluey33]

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.

[LatinR33]

hahaha you sound like me I need to have everything running neatly too. Ohwell see how I go.

[bluey33]

Goodluck with it! Let us know how u go and what you had to do to fix it.

so how thick should you go if you wanted to try this out?

thanks

Have u checked if it goes away when you press the clutch in? If it does as you lightly press on the clutch, it might be a bearing or the ball/fork pivot joint.

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.
