Injectors Or Tappets Making Noise

[dejanz]

i know this has been discussed before, but my enginee is making a tapping noise from idle to 4krev its always there i am currently looking at getting a screwdriver and listening to the diffrent parts of the engine. its either injectors or tappets....

could cleaning the injecters fix the problem if it is injector related.....

i bought the car and it didn't make that much noise but now after the first oil change its always there and anoying... any ideas how to fix the problem

[grim32]

just a thought, did u put the right oil in? and enough of it?

I mum used to have this problem with her FTO - turned out to be the tappets, just needed a slight adjustment

[Craved]

may have always been there, but the previous people used a thicker oil to tone down the noise..

my rb25 developed this noise after about 80,000k's of use. i was told by several work shops that its fine. engine @ 130,000 and still going fine on same injectors. they used to be silent as then one day noticed they make tapping noise

I've got the same sound in my R32 RB26

So do you guys think that it's the tappets or the fuel injectors.

I tried listening with the stethoscope thingy and couldn't tell where it was coming from.

If it is the tappets and it doesn't get louder do you think that it'll be alright.

Is there any sure way to tell. I'm thinking about throwing in some thicker oil to see if it goes away, otherwise how would I tell which it is?

Is it more of a ticking sound rather than a rattle?

I've noticed that my last 2 sets of single pintle 550 injectors were pretty noisey and that was a ticking/clicking sound.

The last set of buggered lifters i heard were more of a rattle that got significantly louder with revs. There's a big difference in the sound. What sort of car are we talking about here as an rb doesn't have tappets.

Right right, Lifters, I don't know what I was thinking.

Which reminds me, I have yet to put a load on the engine, so the lifters might not be tight yet. The motor probably sat for at least a year so I'll have to see what happens once I get it out on the road.

Yes, it's definately a ticking / tapping sound. The frequency increases with rpms, but doesn't get any louder. Do the stock injectors make some noise themselves, I mean 440 is a pretty good size injector.

not sure mate my rb26 has 550cc injectors and it makes a similar noise to what u r discribing and fairly loud to, also a slight noise from the lifters in my car but can hardly hear it ova the injector noise
