Getting occasional quick puff of not very thick, white/gray smoke immediately on startup in my LR3. Sometimes it will go away for months, sometimes once or twice a week - this is one of those weeks. Runs smooth and fine before and after. No loss of oil or coolant. I occasionally get a P0420 - which a can of Cataclean solves - but it’s not directly correlated to these individual smoke events. I’m leaning toward possibly a partially stuck/leaking injector. Have tried some injector cleaner, including BK44, in the past and it’s not made much difference. Any way to hunt this down further until I get a code for a specific cylinder? Frankly the issue is more a pain in the ass (and mildly embarrassing) than anything else so far
