My 2002 alh has been rough on start up for a while. Lots of white smoke and sometimes it would shut off seconds after turning ignition. I just attribute it to cold starts this winter because it is worse when it is cold. I performed my last oil change myself, only 3000km from the time my mechanic last did it. I noticed before the change my oil that the oil level was high, almost to the top bend in the dipstick tube. This was strange to me but I didn’t think or know much about what caused it, just thought my mechanic overfilled it? I performed this oil change early cause I planned to get an oil analysis done to see if I uncover any hidden problems. It came back with lower viscosity which I brushed off for the past 2 weeks because I was extremely busy and stressed. The v100 was found to be 9.3 when it should be around 11 for the 5W30 oil my mechanic had put in. I have been driving almost 2 weeks until this clicked with me and I had breathing time to think. I checked my oil level again today and it is high already, to the top bent part of the dipstick tube. I filled it exactly too the half way mark when I filled it last. I looked at the injectors and the very left one was wet. From a quick search I can have a bad seal (washer) on the injector, a leaky injector, or something else? I’m assuming the white smoke on start up is unburnt fuel but I am a novice when it comes to this stuff so any guidance is helpful. I feel confident taking an injector out but am clueless when diagnosing the actual issue. And fyi I have DLC1019 injectors installed by the previous owner along with malone stage 3 and some other mods. I also recently diagnosed slightly retarded injection timing with the vagcom but haven't gotten around to fixing it yet.
