hey everyone i have a civic with an h22a (obd1) in it. my car was stolen but retreaved (lucky me ) only finding that the theif blew out my oil pump. ive been on what seems like a never ending search for an oil pump everytime i get one i get the wrong one some how. the swap was done before i got it but i have taken the engine out rebuilt it and added plenty of my own **** to make it a bit more legit. my three questions are:1 why does my oil pump have those 2 holes above the crank shaft but the only oil pumps that have it are for the h22 a1,a3, and si? 2 what are the diff. h22 variations as far as litres go? h22 2.0 2.2 etc. and 3 how do i become a non triel user?

 

OBDII oil pumps have the crank pickup on the oil pump where OBDI's have it in the distributor. the oil pump will still work it just got two bolt holes as you said. doesnt mean you need to put anything there
