White smoke from exhaust

mardi 14 février 2017

Hi guys,
I'll start from the beginning in explaining what's happening, and try to provide any information that might be useful.
Today, I was driving as usual and as I came out of a light I shifted to second and began overtaking someone. However, as I was doing so my accelerator pedal felt.. sticky maybe (that might just have been a placebo for what the car was doing) and my acceleration staggered, for just a couple seconds and then all went back to normal. However, when I looked in my rearview I noticed my exhaust had dumped a large amount of white smoke. I finished getting to my destination without anything else happening, intending to attempt to diagnose what had happened later. When I got back to my car, I started it up, and was greeted with this



The smoke was white and pouring out in ridiculous amounts. I can't quite determine the smell. However, I drove a couple blocks and the smoke went away completely; I parked and checked the exhaust as it was idling and it was perfectly normal.



Other than the moment I described before, the car has driven the same as usual.

Researching my issue I've seen a lot about coolant seals and this seems possible. However, I could be totally wrong but imagine that would result in a constant smoking? I also haven't seen signs of the engine overheating and the temperature gauge hasn't moved past it's normal ~halfway point. I've not had any dash lights while driving. My coolant light does occasionally come on momentarily, when I rev the car up (around 4k rpm) before turning it off, but never persists.

Some other information that might have value:
I've just hit 3k miles since my last oil change (topped up 1500 miles ago)
My ignition coils and spark plugs were changed just a few thousand miles ago
My car has an OMP adapter

Any help is greatly appreciated, thanks.
