Nosiy/Ticking injectors once engine at running temp?

[Rusteee]

Hi there

I am new to this forum, and have tried searching to see if anyone has come up with a solution, or had this problem but couldn't really find any solid info. I have recently brought a 97 BZR Trueno, only done 100,000kms, drives like a dream but am worried about a abnormally loud ticking noise coming from the injectors once engine running at optimum temperature. Firstly being paranoid seen as I'd just brought the car I was thinking the worste case senario such as rod knock or something, but listening carefully, the noise sounds like its coming from the injectors. Am pretty sure its not a tappet noise as I spent quite a while trying to trace the noise, plus changing to a higher quality oil + power up, the tappets (or lifters ) sound fine. I hope this gives enough info to not be a useless question lol, will I need to replace injectors? Was going to try that injector cleaner/valve protectant octane booster, but would like to get some advice from someone who knows a bit more about this then I do. Any help appreciated.

Cheers
Russ

Have a search on VVT pulley rattle, it sounds like really loud injectors, and gets worse with temp. Doesnt really affect anything, just gets noisier and noisier.

im 99.9% sure its vvt pulley.
ive not come across a nosy injector on a blacktop ever. on honda b series engines plenty.

it probably sounds like the injectors because the vvt pulley is on the same side and the cam shaft will transmit the sound down the flank. did this noise come after you put in the "power up"? these engines are very sensitive to different oils.


^^^^oooohhh bet me by 1 minute

[Rusteee]

Dammit why did I not think of that, you know that really sounds like thats what it is. Because I also hear, like not really bad but you can actually here the pulley spinning as if something is loose... sorry if that sounds dumb lol.
No I just done the oil change etc because I just like to do that when I get a new car lol, I used 15W 40 + the power up. Only reason I used power up is that my older cars had a bad case of noisy tappets, and once I tried power up it sounded like a new dam enigne lol but i spose for $180 a bottle of 400mls it should be a miracle oil hahaha.
So you rekon I get the VVT pulley done/checked? I've been told to stop worrying seen as its not affecting the way the car drives, but it really is an immaculate BZR and it sux when I can hear a small ticking outside the car at idle x]

[frost]

well most likely it will cost you about $600-$700 to replace the pulley by a mechanic, so its up to you if you can live with the ticking or not. as said by Dell'Orto it wont affect anything.
we live with the ticking in my girls bzr. and my ae86 is starting to do it too.
also castrol magnatec is pretty much power up but cheaper and in a bigger bottle. but dont use magnatec in your bzr, it will drink it like a fish.

[Rusteee]

Oh true thats a bit steep lol. Well I have every single service recipt for the car since it weas imported, and for the 100,000K service they done absolutely everything on it, but it says they took the belt cover off and said it had recent replacment so they never done it. I had our local check it out and he said the same but then said hes seen belts at 100,000k come off looking like new.... So to be sure I think ill get it done, and I spose would be wise to get the pulley done at the same time? already has to get the exhaust mounts and a few other things done since buying the car a week ago, all the things that didnt show up when I went to check it out lol but oooo well beuty of buying 2nd hand cars i spose. Thanks heaps for the help ay, bloody good!!!

[frost]

cam belt should always be done yes, but the vvt pulley wont need to be. and your smart for doing so much service on the car first thing. I've seen cars come through the shop with oils looking like it came from the local fish n chip shop. and the owners wonding why there cars run like crap.

[Rusteee]

Oh yea definetly ay, because they dont garuntee the belt has been done i will get it done soon just to be sure. Is there anything I could try to stop the noise? or the only cure is to get the pulley replaced?
I know ay some people are shocking when it comes to servicing there vehicles lol, I usually do mine every 5000k's and check the water and oil every few days just to make sure its all cosha, I spose you could say im a bit too fussy hahaha

Just save yourself some coin and forget about it. All 20v's have this trait, its nothing to worry about.

[matt dunn]

but dont use magnatec in your bzr, it will drink it like a fish.

what oil dont they drink, as if there is one that it wont,
i'll try it in our bz-t.

true.
though ours tend to eat less when i use castrol edge

[Rusteee]

Oh true? I just used... shit i forget what it was but it was one of the up class bloody mobil oils 15w 40 and added about 110 mls of power up with it. I've already driven it with a heavy foot for the last 2000k's since and it hasn't seemed to use any oil. What makes them use oil apart from buggered rings or tired engine? Or is that just how they are

[Rusteee]

Update...
Just got the cambelt and stuff done today, hoping that there would be something wrong with the vvt pulley to so i could get it replaced at the same time, nothing! so $1000 later and it still sounds like shit...
It really does sound like noisy injectors (almost like a bloody diesil), but could that be a possibilty?
Also the car has a straight pod/foam filter with the temp sensor removed, would that effect anything? I notice if I cruise for a while and slighty (as in a couple of mm) move my foot off the gas the engine kinda freaks and shunts as if it misfires or something and then carries on fine, only does it every now and then, could that be an effect of the air filter and no sensor? Its probably sucking in hot air to, Im hoping to get a factory sensor + airbox tomorow.

Thanks heaps for the help ay! Just kinda dissapointed i may have a brought a low milaged lemon

[xsspeed]

search for 4age or blacktop or 20v hesitation, there was somthing on this not so long ago.

yes get rid of pod and return to stock air box with temp sensor.

Mine does this every now and then and thats with the factory air box. I got told to clean the throttle bodies as they could be sticking slightly due to a build up of grim on/around them. I am yet to try this tho

[sergei]

Regarding oil I use Castrol Protec and it seems fine my 20v (which is has done ~250k), it runs quieter and doesn't seem to drink it....

Hi Rusteee,

Did you ever get this resolved, I too have replaced my VVT pulley which did eliminate all noise from the engine.

But within the last two days mine has now to make a tapping noise only present on acceleration.

I really thought I had cleared up all issues with the engine until this :/

Mine on occasion will also have a "lurch" when buttoning off the throttle.
And it also happens at random times but more often than not around buttoning off at 100kmph.

Not often but on occasion - I would assume that this is a grime build up on the quads.

Be great to here back if you eliminated that noise.

[Dopamean]

BUMP!


Anyone have any suggestions?
I know it’s not the VVT pulley as this has been replaced.
Oil has been changed recently.

Sound is not coming from the "pulley" side of the engine.
I think something is warn because it comes and goes.

Sounds like noisey tappets but only from one side of the engine.
Any possibility that my VVT sensor is warn as power seems to not be quit right:S




Any suggestions?

Think I need to change me handle to "major freakout at any noise"

[BZR4AGE]

Dopamean, I had the same issue once, and is on the cam side only. At the end, it ended up being a loose mounting bolt for the alternator! it took me ages to figure out what it was. Try that.

In terms of ticking injectors...i have it too, and i had it checked etc etc, and they are all fine...have heard someone saying that ticking injectors = healthy injectors (someone correct me if I am wrong).

and I know is not the VVT pully, because I've changed my cam gears already to non-VVT ones.

Thanks mate, your probably right.
Under the hood for me tonight sigh

So it was not consistant?
I called TAMA Auto's and the guy I got was quite helpful I have to say as he gave me the time of day but couldn't suggest what he thought it was.
"Strange" was the words he used as he had not seen this before.


Any other points to take a look at are welcome.
Thanks.
