Only from top. Of the two places bolted, the front one easy, the rear a little harder but not difficult. Unbolt ps res. & remove oil filter cap. Don't replace the knock if new plugs eliminate the knock. I think in my case I have cyl 4 plug getting damaged from too much heat. But I do think the knock replace helped. I do wonder if the knock "microphone" degrades.
