So today when I was on my lunch break at work, I decided to drive my car(99 civic si) to get a bite, and when pulling out of the yeild lane it was completely clear(this is on the bottom of a semi-steep hill) and so when I go to pull out, there is suddenly a car speeding up from behind, so I quickly opened the throttle to get ahead. Anyways, the car had just been started only 20 secs prior to this, and I wasnt really thinking like oh yea thats not good for my motor.

When I pulled up to the following light and was idling, my motor was making a sound that sounded like crickets constantly chirping. I don't know what that was, never heard it before. Now it's still making the noise, but not as loud and obvious as it was before.

Does anyone know what this is????

 

did you check your engine for crickets?

i don't know exactly what you mean, but could it be your valves? thats a tapping, but maybe you could percieve it as crickets, don't know how much that helps... i tried

 

what??...a em1 should not have any problems revving to 6.5k anytime...but you should get that noise checked out

i guess thats true, but i wouldn't reccomend it when the engine is cold, no offense man, but i hate to see how you treat your car...

 

Dude no offense to you.. but can you read?? I took the time to explain my situation in full detail so I wouldn't get accused of trying to "race" or "abuse" or anything like that to my engine. MY car is maybe hitting redline 3-5 times a day on average, other than that I take it easy on the public roads. I can't describe this noise I hear, just sounded to me like crickets.

 

3-5 times per day is MORE than excessive. Hell I can go several days without even getting on the secondary cam profile. Still I wouldn't worry about doing it once.....FYI your car shouldn't even engage VTEC if its not at temp.

 

hey back off buddy, i'm tryin to help you here. YOU are the one who can't read, i wasn't even talking to you, who's that quote of mine by? could my response be to that person, I THINK IT IS!

 

you can rev to revlimiter at any time...although not recomended....

i wouldn't do it when it was cold....

engine will not engage vtec unless these conditions are present
VSS is actived (you are moving)
Oil pressure (you gotta have it)
engine temp (has to be to temp if not vtec won't engage)

now this is null and void if you have an aftermarket ecu/vafc etc...

 

did you have the same problem after you turned it off and back on? Only reason its bad to take a cold engine that high is abrasive wear on items because oil pressure hasnt built up yet....shouldnt cause crickets in your car

you seem to be ill informed on WHY you shouldn't push your engine when its cold, it has plenty of oil pressure, if it didn't, your engine wouldn't last very long at all. when your engine heats up, the metal expands, and the tolerances are set up for a warm engine, when the parts are expanded, it doesn't expand much, but again the tolerances are very precise

 

It's probably a coincidence. Check your belts for wear, it's probably just time for basic maintanance. Your car will be fine; it's a Honda.

 

btw i'm not trying to sound like some snooty know it all(theres a lot of those ******* around here), after reading my post i think it sounds like that. just trying to inform you

 

It should be fine, you're probably just over re-acting.

If you are seriously concerned... get a tune-up, it can't hurt anyways.

 

so what your saying is that rapid cooling and heating of the piston is what is bad for it? You cant tell me you dont build more oil pressure after oil heats up

No, he is saying that when cold there is a lot of oil pressure (which is true) and that the engine's components i.e. block, pistons, etc heat & expand at different rates, and that the engine will not function at it's optimum until all components are heated up to normal temp. The block will heat slower than the pistons, so clearances are tighter right after startup than they are at normal temp.

Does that help?

 

Yeah and I did not know that...I thought it was the other way around. Thanks for the info tho

 

"If you are seriously concerned... get a tune-up, it can't hurt anyways."


Tune up? What, so they can replace the belts and spark plugs? Its not like an old school motor where you actually TUNE it up. Sorry...not trying to be a jerk. The term "tune up" on MPFI motors is kind of silly in my eyes.

 

hahaha... redline only 3 times a day? wow that is weaksauce lol

 

probably just a belt. When you warm up your car, sometimes moisture will build up on the belts causing some squeaking sound. It's normal, no biggie.

haha thats what I'm talking only 3 times a day and someone had the gall to call that excessive. They should of bought a pontiac sunfire in pink with an automatic.

Tune up as in check valve lash, oil change.

The only noises ive ever heard that resemble crickets is when you need a valve adjustment or you in need of an oil change. Other than that the noise could be the belts, like previously stated.

And as Roti said, you are probably being paranoid.

hhhhhhhhhhhhhhhhhhhahahahahhahahhahah a

 

Hmmm, yeah well some of us don't really beat the crap out of our cars unless we're on a track. I suppose along with age comes maturity. &lt;me on my moral high horse&gt;

Haha good stuff.

 

A/C belt? was your AC on? because when mine was on a bit ago, i got on it and now it has been making a cricket sound when its idling, its the ac belt slipping alot from me getting on it...

but see if it needs to be tighter, i fixed mine and its fine now...

this may not help but good luck
