So I did the piston soak like I said in "Overseas Piston Soak" in the additives forum, and now I am getting a puff of smoke after sitting at a light too long. I started noticing it after I got the oil changed that day. I got it changed after the piston soak, so there I was used to the smoke coming from the LC. Any ideas on what is going on? ARX will be on it's way soon, but I am wondering if I didn't break something that ARX won't fix.
