ive looked up on many diagrams and all show same style oil pump how do u tell if its obd1 or obd2? and what type is this......

 

It has the mounting locations for the TDC & CKP similar to the OBD2 F22B* oil pump housing. However the mounting bolt pattern and casing design is not the same. That is an OBD2 H series oil pump.

OBD2 F22B* Housing


OBD2 H22/23 Housing

 

thanks

 

No Problem

I'm so used to Accords and F22s. If you have an H22/H23 then yes this is an OBD2 oil pump housing for those blocks.

The red circles show the different mounting points on the H series. The blue are the mounting points for the TDC & CKP sensors. The OBD1 housings do not have these.

 

awesome what about the crank gear l was told with obd2 u have to use obd2 gear cuz of magnet? l thought obd1 and 2 had a magnet

 

Yes you need the OBD2 (96+) balance shaft drive gear and timing belt drive gear. they have teeth that the magnetic sensors detect. the OBD1 gears do not have these teeth.

This is an example of an OBD2 BS gear, notice the 12 teeth, or pads around the outside. That is what is required for an OBD2 sensor setup.



The OBD2 timing belt drive gear has two teeth (points on it)
