yeah im going to hook up to my buddys skid steer + trailer and go on a little road trip.

 

There is the factory tool that Ford would use and there are those that have made a tool on their own. Here is a thread with the info and directions:

I have 95,000 miles on my truck, when my oil starts getting close to needing to be changed I notice more vapor. I also see more vapor when it's cold outside, if you can see your breath you'll see a bit more vapor.

 

i think allot of the oil vapor is the piston cooling jets squirting the mist of oil onto the bottom of the pistons.

 

I never thought of that, seems logical.

 

Here is mine with ~230k.

didnt see anything coming out.

 

what kind of oil you using?

 

Mobil-1 5W30

 

i wonder if the SVO he's burning, plays a role.

I got 106k on mine, and the ccv and fill cap smokes, not as much as the OP. Drove me nutz for weeks, think'n of it smoking, til i came to conclussion, the "majority" of peoples' do.
