Yup... confirmed there is no more smoke.
Thanks all.

Does this sound like something to be worried about? Any thoughts on what it might be?

White "smoke" is steam and there is only two sources of water. Condensation in the exhaust system, which should blow off as the exhaust system heats up and the coolant system. How is your coolant level? Any ...

Anyone out there know what O ring size is used for fuel injector? I believe fuel injector is part # 30777501 and o-ring set is part # 30713614.

I need to remove the fuel rail on my 2007 XC90 3.2 FWD to access screw that holds the pressure sensor. My understanding is when removing the fuel injector ...
