VTEC Gone!
Hey guys, had a disaster last night. Quite hard to describe so bear with me.
Last night I was driving home from work, I was driving quite sensibly. I turned left to go up one of my favourate straights. I decided to open the taps a little and have a little fun. I was in second gear and had just past the glorious transition from normal to VTEC. I kept the foot down but at 7000 disaster struck. I can only really describe it as something blowing. There was no bang but it felt like there should have been, there was a large and severe jault, Felt as if I hit something kinda. I straight away took the power off and dipped the clutch. I just assumed I would have no power left and the engine would cut out. It didn't, I kept on driving home very Hesitantly. After about 15 mins I plucked up the courage to give it some welly again to see what had happened and whether it had effected anything. Well it did, I can still rev really high but there seems to be no VTEC power kicking in at all, there is no longer that unmissible sound of the VTEC rore. It sounds exactly the same all through the rpm range. Any Ideas guys? I apologise about the essay and the crap description. I looked under the bonnet when I got home and didn't notice anything however it was very dark, think I will have to wait for the weekend to have a good look.
THANKS Alex

? Oil level ?
IIRC, low oil level disables VTEC but this doesn't account for your description of "something blowing".
I'm sure someone on here will come along any second with the answer.

Well, if there's no running problems/noises, it's unlikely you've broken anything as such. The first stage cam will barely allow 7,000 rpm due to the gas flow restriction (like most 2,000cc car engines!).
Which suggests low oil is preventing the VTEC plungers from working.

Was the engine fully warm when you first tried to use vtec? If the engine's not fully warm there is a hard limiter which when you hit it feels like somethings broken!
VTEC should come back when the engine warms up though.

I have to say that was the only thing I was guilty of, the car was not fully warmed up. That is what if felt like a very harsh limiter. But was not kicking in at all on the way home, maybe I'll give it ago at lunch time and see what happens. Cheers
