yeah i have a b18a1 on my car too, and i noticed something weird..or what seemed to be weird on my engine. when i look at it from the front, right next to the distributor, on the head towards the front of the car, there is a hole which has bolts that looks like something was supposed to be bolted on there. im thinking either the crank angle sensor or cps?? but instead there is a black rubber cap coverin it. im thinkin it all depends on if my distrbutor has that sensor in it...but any help? its obd0 too.
