anyone ever had this problem with vtec?
the problem is everytime i get on my little z6 powered civic enough to run it through 3rd gear, i eventually ( still in 3rd ) throw a code everytime. the code is 22, vtec pressure switch. it only ever comes on during a hard run usually in 3rd.
i have already tried different pressure switches, spool solenoids, ecu's , everything i can think of that would effect it.. and yes my oils good
anyone every encountered a similar problem?
thanks for any input/help

Re: anyone ever had this problem with vtec? (92sihbk)
hhmm wierd I had the same problem, my vtec would cut out in hard runs in 3rd or 4th. I have a JDM ITR and it was throwing the vtec pressure valve code, but the thing is the jdm motor doesnt even have one... and I was running it with a usdm ecu. So all i had to do was tap the vtec pressure valve wire into the vtec solinoid wire and it works fine (constant 12 volts). But i dont get it because z6's are usdm.. I would check the wiring to the vtec solinoid. Sorry i couldnt help you more. Ill look into it

Re: anyone ever had this problem with vtec? (Panda Eg6)
yea Ive had the wires jumped before and it did keep the code from being thrown, although i beleive it just masked my problem, because I dont think it should be losing oil pressure like that.. thanks for the help

Re: anyone ever had this problem with vtec? (92sihbk)
I took the Z6 out my hatch to put in my 4 door. in my hatch the engine was using the original Si/EX harness, but i wanted to save that for my hatch, so i used the DX harness from the 4 door and wired up vtec. it took a few tries but i am positive i have it wired correctly, and i am even using a different virgin P28. Although, i still had the same problem in my hatch with the original harness. It still occurs in the 4 door.

Re: anyone ever had this problem with vtec? (cln92eg)
yea it sucks, VSS is good, cluster and all is good.
i know single cam crossover is pitiful compared to dohc, but every other z6/y8 crossover around is very noticeable for a stock engine, while my engine has a cam/ported head and even higher compression, and there is no crossover..
it always led me to beleive that somehow ( call me crazy ) oil pressure is seeping out of the rocker arms enough that they arent pressureizing enough to engage the locking pins...
i have a whole nother rocker arm/lost motion assembly that I wanted to try on my head but someone told me that i couldnt swap the whole assembly out.. can anyone every done this and had it work fine?
Thanks

Re: (z6hatchboy)
tried it
can anyone confirm if i can swap a whole rocker arm/lost motion assembly ( from the cam UP ) from one head to another? one of my friends said they are surface ground together as a matched set I guess when they are manufactured.. so it wouldnt work...
but i dont know about that and thats why im asking you guys if it will work or if anyones ever done it..
let me know
thanks for all your input

Re: (cln92eg)
Its coming along, put the fmic on today . Heres the thing that i seen in the manual that have to be right for vtec to work: Engine speed above 2500rpm, Vehicle speed above 3mph, water temp, engine load. Try looking at those and see what you can do.
