is this due to the fact i have a non vtec oil pump on my car?
it will engauge in 1, 2 and 3rd, sometimes at the end of third gear around 7,
i have an LS tranny, and the gears are longer,

Maybe sence the gears are longer and it takes longer in 4th and 5th gear to get to 7 grand the oil pressure is not where it needs to be...
any suggestions?

 

ttt

 

vtec only works in 3rd gear

i know that doesnt help, but why would it engage only in 3 gears???

maybe it is and you just cant tell???

 

if you max out 3rd and in vtec you're already in the 100mph range what are you doing trying to pull vtec in 4th and 5th gear are you trying to go 200 mph hahahaha.

 

WOW , u did not help one bit,
the end of 3rd gear is around 85 MPH, and and the end of 5th would not go to 200MPH .. WOW
and it engages in 1, 2, and 3rd, and then no 4th or 5th, it throws a check engine light!!! every time, i know its not engaging...
allright, Tech help now.. please

 

what rpm does your vtec crossover at?..if your in 3rd and your nearing max...once you shift into 4th your most likely going to be in vtec range still and same in 5th, the tone wont change since your already in vtec. this applies if you have a chipped ecu and shorter gear ratio...but i assume this is happening though with your car.

 

it is at 4800, there is a check engine like for the vtec code.... oil pressure
i have the ls tranny.

 

do you have a knock sensor hooked up? it sounds like my old setup when my knock sensor came unhooked. that would cause you to throw a check engine light in 3rd

 

yeah double check ur sensors
i had the same setup as u a few months ago
i had no problem with the ls tranny

and is the knock sensor the green plug on the back of the block?
whats happens if i unplug it while the car is runing?

 

there is the gay light.
and thats in 5th gear, i let off the gas some, thats why its just right about 4500RPM

 

ttt, what is the green PLUG ON THE BACK OF THE BLOCK, next to the oil sensor.....?!

That is the knock sensor. It shouldn't go on when vtec engages, though. If it is bad, it will come within a few minutes of the car running normally.

It doesn't have anything to do with oil, but if it is unplugged/broken, vtec will not engage. It should be throwing a CEL code 23 if it were bad/unplugged.

 

ok, thats not the problem them...
thanks for your help... its got to be an oil pressure issue, sencing im geting that code,
(vtec Oil Pressure)
and since i dont have a non vtec oilpump on my lsvtec, doesnt that make sence?
i need some lsvtec people on here who have had this same issue. i have tried searching but cant find what im looking for

 

I am hesitant to say it is the oil pump. Have you checked the code (if you can even check it)? Have you pulled the vtec solenoid apart and checked for any problems there?

 

your lacking oil pressure at top end. the non vtec oil pump is not sufficient oil pressure to activate the solenoid. upgrade to a gsr or a type r oil pump. it happened to a friend of mine that put a gsr head on a ls block. good luck.....

 

get a oil pump from a gsr

 

its most likely not the oil pump i had a ls oil pump on my turbo set up and never had oil pressure issues

 

issues or not i would have done it the right way the first time.

p.s. we now know its oil pressure and some say it probaly isnt the pump... well then what the expletive controls oil pressure? I think for damn sure its the shitty ls pump
