VTEC on intake cam only?!?!
My friend has a B16A with ITR cams in it and it has run fine for a couple years now, and now vtec is only working on the intake cam. what could be the problem?

Re: (superfast666)
vtec still engages, but you can only hear it on the intake side, not the exhaust side, like you've been able to hear for the last 2 years. The car drives like it always had when in lower rpms, but once vtec engages it pulls less then it used to.

Did you ride down the road with someone on your hood or in your hood to listen to the motor close enough to tell what side the noise was coming from? Vtec only kicks in when the wheels are in motion and you hit a certain rpm.

Re: (philkehn)
do you people think i am an idiot!? itr cams in a b16 make a very loud crossover, and its obvious that the exhaust is not crossing over. is it possible for something to be blocking the path of oil after the vtec solenoid?

hey now i take offense to that
seriously though what wrong with a VTEC light? I like mine it reminds to not waste gas and its also nice to know that VTEC is actually working. but then again if it wasn't i am sure i would be getting a CEL.

Re: VTEC on intake cam only?!?! (dividedas1)
tried searching a bit for you online couldn't find a single thing. so i would say

would be a good place to start. so does vtec kick like a d16 instead of a b16 in that thing? lol sorry i just dont really see how it would be possible for one cam to engage in vtec while the other one didnt. seems like either they are on or they are off. but then again what do i know

Its literally not possible for only one cam to engage, unless every one of your lost motion assemblies on your exhaust side have broken the pressure pin.
Which has never happened before.

Re: VTEC on intake cam only?!?! (dividedas1)
I'd think it could actually be possible because it is locked in by pins through the rocker arms so say 1 side got bent or something and was not locking into place.......Just a theory...
My guess is that it is crossing over but your soleoid screen is dirty/clogged and needs to be cleaded out (like the O/P said). Generally I'll take an extra 3-5 minutes and bleed the solenoid as well to make sure there are no burps in there as well.
Good luck.

The VTEC lights are good if you're not sure whether it's sending the signal or not. You can diagnose a VTEC problem faster that way.

LoL!
That's exactly what I was thinking, or a lil man under the hood or something.

Wait.... so you're telling me that you need a light to remind you that you're wasting gas if you rev your engine above 4800rpm...?
Like I said before, it IS possible for a mechanical failure to prevent the locking pins in the exhaust rocker arms from engaging, but it's HIGHLY unlikely.

Re: VTEC on intake cam only?!?! (dividedas1)
we first played with the timing to see if it jumped a tooth. we pulled the vtec solenoid, and cleaned the screen.
seeing how the motor has TWO cams, there for TWO sets of rockers to crossover, i do see it possible for something to be stopping the flow of oil to one.
the motor is normal on the low profile lobe, then a muffled, but loud crossover, then the motor becomes a turd and boggy.
idk we'll figure it out, maybe check timing again. ....thanks

Yeah, it's possible. That happened to a guy on here - but it was both rockers jamming up...though IIRC it was his fault for not doing something right, he fixed it, and it worked fine.
Though the concept of "I can hear my VTEC, it's only half working" - is just funny to me.

lol no i don't, i am just honestly a big smart ***. but how ricer is that light really... maybe if like you had it lighting up VTAKK or something ghey like that it could be ricey. i still think gauge faces, interior paint (other then making it all black), seat covers, neons etc etc are more ricey then a vtec light. any who as well all know here on h-t JDM's the new rice anyways. lol

Like Syndacate said, it depends how you use it. If you only have it as a diagnostic, then it's not bad. If you have it just because you want a special light that turns on when the solenoid is powered, that's ricey.

Re: VTEC on intake cam only?!?! (mcvtec)
and to ddd4114 i agree with ya 100% i bought my car with a vtec light... i ended up changing what it lit up because it did imo look kinda riceish... but it definatley came in handy when my vtec pressure switch wire came undone and i had a cel and no Vtec, pretty much narrowed down my problem with out even getting out of the car lol.
