My engine is making a ticking noise at around 2500-3000 rpms. I opened the hood and it sounds like it is coming from the intake manifold area. This has been going on forever, and it isnt a new problem. Does anyone know what the sound could be?

 

valve adjustment

 

Usually it's your fuel injectors. Honda fuel injectors make mad 'ticking' sounds sometimes. It's normal...

 

try a valve adjustment first, thats the "ticking" noise that most people commonly hear.

true..describe the ticking. does it sound like a diesel?

 

i have a loud ticking sound at idle as well. when i added my turbo, it got louder and with some sort of a hollow like sound along with it.

 

If it's the fuel injectors, there is NOTHING to do. Healthy fuel injectors make a tick-tick-ticking sound; usually loudest at idle. That's how you know they're working right. If they make a 'thud', then they're most likely bad. However, 'ticking' is good.

An easy way to isolate where the 'ticking' sounds are coming from is to get a piece of PVC pipe, put one end to your ear and point the other end at the individual injectors or valve cover, et cetera, kinda like a makeshift stethoscope. That'll pinpoint it...

 

Forgot to say that I I just did a valve adjustment this morning and the noise is still there.

I think it might the injectors, but is it normal for it to "tick" only at around 3k rpms?

 

Yes, once again, fuel injectors are supposed to 'tick.' This is normal...

 

yeah, i always noticed from B and H series motors. D series don't really 'tick' at idle, or aren't as loud. a lot of the people i run into that buy their first DOHC VTEC always wonder why their engine 'ticks'.

 

This falls into the "if it ain't broke, don't fix it" category. You'll only notice the 'ticking' sound when the hood is open and the engine is running. For most ppl, that's like a twice in a lifetime experience...
