alright i posted a thread a while ago on how my gsr smokes when vtec hit, so anyways i just took a long drive yesterday to do a delivery for work using my own car, a jdm b18c hatch, bolt ons and ctr cams untuned running a stock p72 ecu. I drove a about 200 miles there and back most of the time i was cruising on my first vtec doing about 90/95 most of the way, all was fine until my check engine light came on, and vtec wasnt hitting, i checked my oil levels to see if they were cool, i was short so i added some more oil and a vtec started to work again, this was yesterday, now when i hit vtec he goes off sometimes and doesnt do **** at all other times, also the car feels like its struggling really bad around between 7 and 8 thousand rpms, when vtec does hit it's interrupted meaning vtec will shut on and off between the time it takes to engage to redline, everytime vtec cuts off, i see a puff of whitish bluish smoke shoot out, you can even feel the car shoot it out, i know blue means oil, so does this mean that my rings have diffenently gone bad???

 

I"d check your oil again today and see if your car is eating the hell out of it

also you may want to do a compression test

 

thanks, checked it today, lost some oil but not much

 

Could be your oil pump!! Could be your v-tec solenoid, check everything.

 

also check your knock sensor...vtec wont crossover unless your knock sensor is operational

 

i think your computer is very smart by not letting you engaged vtec,belive it or not this safes a lot of peeps motors out there. well there is def something wrong with the motor, do a compression test, hear for any knocks, and if your adding more than 2 quarts a week def time for a rebuild.

Same thing happened to me. Replaced the pump with a new one and everything is fine now.
