Does anyone have a link or maybe know some info on B series oil pumps and if their diffrent???

I cant find any info on B series oil pumps anywhere......

i need to know if theres a difference in the VTEC and non VTEC pumps

Ok well long time searching and i have finally found out the big secret to the oil pumps. The only thing thats different in them is indeed just a washer.

BUT that washer is the thing that changes oil pressure because takin tht out allows the hexbolt plug to sit lower and compress the relief spring a little more.this causes higher oil pressure before the plunger is lifted off the seat to bypass the oil


so diffrences are infact oil pressure because of that little washer
