Vtec won't engage
Hello guys !!
I'm new to the Honda game.
I bought 94 civic DX for 1k from a friend.
it need piston rings Burning hella oil so I started saving up.
thinking what best swap I could've got.
Well I was going go with Z6 but one of my friend started talking to me about how fast B18 was well guess what happened next lol I bought LS tranny,p28,axle, mid shift bah bah bah almost full swap just needed motor.
I found b16 pr3 head fully built for $600 I bought it no idea why I bought it but I bought it lol
The next week I found b18c1 short block for 400 I went and bought it .
Started buying new gaskets and all stuff I needed to drop my swap.
I found out after I started the motor the oil pressure sensor was cracked!! There was oil everywhere!! I was **** like a Mf so I tap it and put bolt on it and bought a oil pressure sandwich kit and adapted the oil pressure sensor from there.
I thought it was easy fix but
Now the swap is done running great!! But now I got a problem Vtec don't engage!!! Idk what the hell to do !!! I tried re wired the Vtec wire , tried two ecu p28 and gsr and nothing
Next I checked the oil level and straight wired the VTEC solinoid to the battery and it engages so I don't know if it could be harness or oil pressure sensor that not getting right pressure? Because it running on sandwich kit ?
I'm new and I tried my best but this problem out of my knowledge need someone has more experience can help ? Thanks pm me

Re: Vtec won't engage
Did you check to see if the VTEC oil passage in the cylinder head was clear ??? If the B16A head has been used in a LS/Vtec or CRVtec application in the past, this passage must be plugged from the underside of the head. The way to test this is to run a test hose between your sandwich plate and the 5/16" copper plug at the passenger rear corner of the head... essentially making a new passage for oil to get to the VTEC solenoid. If VTEC works, you are in business. If not, something else is wrong... and chances are good (since you made no mention of a CEL for VTS or VTP) that it is a bearing problem in the bottom end.
