My civic has always leaked oil, i got it checked and they told me they had to flush the transmission and all this other stuff i cant remember, i had my car in miami at a body shop and since my dads transmission shop in near he told me to bring it in an leave it there for a few days to get everything fixed. Now i had this car for 2 years and i have never heard vtec kick in, and nowafter i hit 6k u can hear the change over really good, but heres the problem, i thought vtec kicked in at 5500, and once u hit vtec it stays (ON) for the gear after.I hear mines kick in on every gear and i find that weird.

 

Vtec has nothing to do about gears or speed, its just the rpm. Its diffrent on most civic and I think mine kicks in at 4800 rpm. It stays on untill you go under the limit then it just runs the normal cam

 

My vtec kicks at about 4500. And I'm like WOW!! Just kiding. But yeah I think it engages at 4500 rpms

 

d16z6/y8 = 4800rpm
b16=5500rpm

and vtec stays on as long as you stay above the engagement rpm... drop below it and vtec shuts off.

 

ummm...what happens when you dont feel a boost or here anything different while accelerating and you hit the v-tec range

 

as long as your check engine light isnt on, its working

its not really loud on SOHC
On DOHC its louder

 

lol wow.. my check engine light has been on the hole time i had the car, but i got that fixed there, no wonder i can hear it now.

 

i think its noticable on my d16y8 i can feel a little pull ...and hear it better because of the SRI but ya

 

I could never hear the vtec with the civic 07 lxbut I been driving a prelude 99 and you can hear it at 5000. Its awesome.
