Ticking noise coming from engine bay?
I own a 2000 Honda civic si and as of recently there's been a ticking noise. The noise comes on whenever I cold start my car and when I'm accelerating past 2,500 rpms. The noise is like a ticking/rattling noise. When i cold start it, the ticking is really fast. The thing is, when the car is cold and I'm driving it cold, it won't make the ticking noise, only at start up. When the car is warmed up, the ticking noise doesn't appear at start up, it only appears when I drive it. Any one have any ideas what it might be? Thank you in advance.
Points to remember:
- Cold start=Noise
-warm start=no noise
-driving cold=no noise
-driving warm= noise at 2500rpms+
Get your valves adjusted. A routine job on older Hondas.
Have it checked at your local mechanic/gas station.
It sounds like a lifter is collapsing under certain circumstances. But the first thing to do is remove the serpentine belt in the morning and see if the noise is there to eliminate, that will take out a pulley or tensioner. If the noise is still there then I'm almost sure it would be a lifter.
- Weird whistling noise coming from my ATV engine? So i have a honda 250ex, and today whenever i would give it gas, i would here a strange whistling noise coming from the cylinder block in the engine. When in neutral the sound was not heard. I never heard this sound before and it made me a little nervous. Just wondering if there's a problem with it or if i need to replace something.
- We have a 2006 Honda CBR. When you drive it, there's a loud whirring noise coming the back underneath side. What could cause that noise? The noise is situated around a CV boot on the left underneath side where the differential connects to the middle.
- Mechanic said he rebuilt the engine, smoke coming out of engine, could it be the grease burning off? The mechanic said he rebuilt the engine to my 1974 Honda CB550 I bought from him. Said he rebuilt the engine and is in perfect running condition. He has many bikes lying around and seems as if he is a hobbyist for bikes. He told me that he basically greased up a lot of parts of the motor and it is burning the grease off. The next oil change I do should remove the excess grease.
- If I drop something into the engine bay, can I unscrew the bottom of the car to get it? I dropped something into the engine bay and can hear it landed onto the bottom. On the bottom of the car is a metal sheet. I can't squeeze under my car, but I can feel there are screws down there. Do you think I can unscrew one side of the metal sheet (the side closest to the front bumper), bend open the metal sheet slightly, and poke a stick into it to retrieve what I dropped? I have a 2017 Honda CR-V.
