I have had a 98 lude with a h23a blue top for like 5 years. I’ve blown up one h23a and since replaced it lol. I’ve had the engine apart probably 10 times the cars whole life with me. Since about a year ago the oil pressure light on the cluster stays on all the time but it is only dim. I know I have oil pressure because it hits vtec and requires oil pressure to do so. My thoughts are that maybe the balance shafts are out of alignment but I always align them.. any help would be great.
