I have a d16z6 bottom end and a d16y8 head. Are the d16y8 and d16z6 heads different? Am i suppose to do something with the oil jet since i put a y8 head on my z6 bottom end? Im wondering because my VTEC is not working and it has something to do with not enough oil pressure getting to the rocker arms. I have plenty of oil pressure at the sending unit (75PSI @IDLE).

im pretty sure the oil jet is inside the y8 head so you wont have to fool around with that.

 

i know there is one inside the head its on the top middle on the exhaust side (this is where the rocker arms gets its oil). What about the one on the block? I got the head milled and maybe there is metal shavings in an oil passage or something? I cleaned the oil orifice in the head, and that didnt help anything. What about the one that meets to the block?

 

am i suppose to remove the oil jet on the bototm end? I thought this was only for a mini-me swap? Or am i suppose to do it anyway??

well i took the rocket arm assembly off for the 100th time (i can do it with my eyes closed now) and i sprayed compressed air in the oil orifice under the assembly. And i could feel the air coming out of the hole on the VTEC solenoid (i took the solenoid off also). So there is no restriction there. Maybe nothing is wrong? Maybe its just me? But my DOHC ZC feels A LOT faster than this car does! and it shouldnt.

 

There is a dowel that you have to remove. Do a search for mini-mi swap. 75psi seems a TAD high at idle. I definatly dont think it should be that high, but someone can correct me if im wrong.

 

maybe it is you if the zc had more TQ cause TQ makes you feel like you are going faster than you are a lot. sorry i can't help ya with this cause i don't know mini me swaps or anything!

 

this isnt a mini-me swap its a SOHC VTEC that is built(Read original post for parts list). And its 75PSI at idle because its a high volume oil pump

 

well i advanced the timing about 7 degrees and now it actually feels good on top end. It will break the tires loose at 5,000RPM. IM gonna play with the timing a little more to see if i can get it how i want it. Maybe this is all it was??
