When I rev it up past 5800rpm, where vtec is set, the check engine light comes on, but it won't throw codes when I try to check. There is no LED on my ECU so I'm not sure how to check there either. I ordered the dowel from Acura yesterday, but I guess I need to go back and order the o-ring as well since they probably won't come together. Anyways, once those come I'll put them in and see what happens.
