Re: ? blue exhaust when start/turn over car
Two rules of thumb.
1. blue smoke = oil
white smoke = coolant
black smoke = fuel
2. The best way to narrow down where the smoke is coming from:
drive down the road, if smoke comes out under acceleration it's typically the rings, if smoke comes out under de-acceleration it's typically the valve seals / guides.
