After my truck has sat for couple of hours and it is started up it will blow a cloud of blue-ish smoke out of the exaust. It only does it at startup for a second and the truck runs fine. I did notice thou that the oil was a little low at the last oil change. Do you know what this might be? Thanks

Hi there,

This is often a sign of faulty valve stem seals and worn valve guides, get this inspected first.
