I've just noticed this popping up in the last few days. 93 G, JDM swapped motor has bout 75k on it. I don't believe that it's detonation. My car has a harsh tap tap tap at idle that gets faster as the engine revs but is most noticeable at idle. It's defintely coming from under the valvecover. I'm really worried. Any ideas?

So my valvetrain isn't getting oil. I didn't drive it over the break. My last oil change was about 2k miles ago. I used the long drain mobil 1. It's still full, hasn't leaked or burned any oil. I'm basically planning to change the oil/filter even though its supposed to have 10k miles left on the oil and hope that fixes it. If it doesn't...I think im in deep, deep trouble?
