Start driving the s13 I have. Its a ka24e with auto tranny. Using as a daily right now, until I finish my other project I have. Has a slight tick to it when you accelerate. When its in neutral and you give it gas you don't hear the tick. I am thinking its the valves but not sure. Can you adjust the valves on a KA? Could it possible be something in the tranny? Or is it the timing chain chatter that I hear Nissan's have a problem with? Ask questions if you need more details, thanks.
