Ok i have a ls/vtec build that i finished last month and the only problem i cant figure out is the vtec, the problem is i have low oil pressure, i put a sending unit at the oil vtec port on front of the head so i can watch the pressure when it hits, strange thing is when the car is cold it hits ok, about 60 psi in all the gears, but when at operating temp its about 25 and you can hear the solenoid kick in and out a few times before the cel turns on and its has 16 ohms so its good according to the book.

Im using the GE kit, the oil pressure to the head is good, i have a type r oil pump and there should be plenty of oil. i cleaned the vtec screens and everything is good the lost motion assy are in great shape and i even hooked up vtec to a switch in the cab by just putting 12 to the solenoid and bypass the oil pressure switch, and same thing hits when cold but after its warm less that 25, i have been screwing with this thing for a while and cant get it right, if there are any guru's that have any idea please let me know, i have tried almost everything in the book, Thanks

 

 

im stummped! it has to be a missing o-ring or a leak of some kind somewhere.

Thanks ill give them a shot

 

i think it might be the oil pan or the pick up tube, im going to pull it on wensday and check it out,

 

turns out it was the oil pan, i bought one from my work at <U>AutoZone</U> made the pick up tube hole larger where it sits in the oil and now i have 80psi in vtec, i had only a small dent, but now everything is perfect.
