BS 22

any CELs?

Oil pressure?

HATCHingMN

oh.. and make sure you put plenty of oil in the motor too

papito_85

you can hear it, but it's not as loud as a twin cam.

skunk2eg

maybe you cant hear it, but can u feel the change over?

drowzysleeper

i cant hear it or feel it really. im running like 12to 1 compression so i think i would be able to hear it. what are CEL's?

SOHC4life 96

CEL = Check Engine Light

are you in limp mode? cuz that is what was wrong with mine. check your o2 sensor i.a.c.v. etc.

I havent checked my valve lash since I did my mini me... but I cant hear it either... Only way I know that vtec is engaged is because my oil pressure drops a bit when it engages since vtec is a hydraulic system I watch my oil pressure gauge to see when it engages. I have an intake, edelbrock intake mani, headers and exhaust... My Y8 head is also ported and polished..

my check engine light is on but i think that is from my test pipe it was on b4 this problem i also have a problem with my speedometer it keeps going to zero and staying

egsleepercivic

if your cel is on and your VSS is fawked you won't get vtec

You can hear VTEC on SOHC motors, it just doesn't hit as hard.

It make just be blown, that can happen.

If you have all that you should be able to hear VTEC....i mean with my d16z6 I just had a short ram intake and I could hear the crossover distinctly.

Get an LED, hook the positive up to the VTEC solenoid and the negative to ground......see if it lights up when VTEC is supposed to be engaged.

My SOHC transitions like a **** into vtec. goes from waaaaaaaaaaaaa to WRRRRRRRRRRRRRRRRRRRRRRRRRRRR!

5gSiB20

just like eg sleeper said your vss is screwed as it was in mine so it aint goin to ingage. and even when you get that fixed if your check engine light is still on you got another problem so you still wont be hittin tec

4dr*sleeper

of course you can. atleast i can for mine

drowzysleeper

ok so what is the Vss sorry i havnt learned all the abrieviations yet i was able to hear it before i but now i cant could it just be the vetec solinoid?

Deemeetree

Tell it to speak up. Because, we all know that once you can hear VTEC, you'll think you're going faster.

Its not nearly as noticeable as it is on a dual cam.
