well i converted one of the crx's we have to an ls vtec set up, and i have done a few of them in the past but this is the first one that has given me problems.

B18a bottom end
B16 head
vafc
still OBD 0

i tried running the line to the back of the head.............no vtec
i tried removing the pressure switch and running it there............no vtec

the vafc shows output to the solinoid, and i hear it click but its like no oil wants to go past it, i changed pressure switches twice and now am boggled...........


could the machine shop have fucked up anything in my head when they had it????

i cannot think of anything else that could be wrong, is there any other variables i have not covered???????
