i was wondering how many and where are the oil passages on a vtec block (h22 if you want to be specific)

ive been have vtec issues w/ my h22 since my rebuild... ive checked the wiring, switched ecu's, checked the vss, tried like 4 different vtec sol., tried 3 different pressure switches, even a whole new head.

i tried my old head on another car and it worked just fine... i havent touched the wiring since the rebuild and it worked b4.

it seems i'm not getting enough oil to the head... i keep getting code 22 no matter what i try.

so i need to know where the oil goes through b4 it reaches the head. and i was gonna try to use the golden eagle ls/vtec stuff to feed the head if i cant get it figured out... can i do this?

i havent had vtec in over a year on a turbo h22 fully built... it sucks

anyone?
