cool im going to try that but something tells me is something else.. but its worth a try since im tired of not finding the problem.

 

plus i dont think i ai have a cel but it might have been taken off since i bought the car like that!

 

reasons for no VTEC operation include low engine oil level, VTEC solenoid not opening or the screen behind it is restricted, an engine that has low oil pressure, or an oil pressure leak to the rocker arm assembly. In some cases, when engine work is performed, a missing or damaged O-ring can cause incorrect oil pressure to the VTEC system.

 

i guess i might have to rebuild my head if im going to take it off. i wonder how much does it run for..

 

THANX THO

 

I dont think you need to take off the head to find out why vtec isnt working? unless the head itself isnt good anymore.

 

Hook a gauge to the head at the front by the solenoid. There shold be a plug ya can pull out. Then you can hardwire the selonoid to keep it open to monitor pressure. Dont leave it that way for to long. Is the oil pressure safety swith hooked up.

 

yeah everything is hooked up,oil is good and wired direct but thats a good idea..

 

If your v-tech is not working you should get a new phone or call your service provider and get it fixed lol

 

wow
GTFO!!!

 

what kind of ECU are you using? on what kinda car?

 

re charge your phone

 

all joking aside, what makes you think its not working? Most people write of no "pop" or huge acceleration when vtec kicks in. Not really what it actually does. If you know for sure its not, and no work as been done on the head and assuming the engine is older its probably burning oil and you might just be low. Sometimes its the simple things.
