some smoke at startup
I drive an ’01 with the 4.6L. Truck has 96K miles and no real problems, runs great.
My condo parking spot is on a pretty good incline and when I go to start her up after about a day , I get some smoke on startup. It definitely is oil smoke, can tell from the smell.
It has been doing this for just the last month.. Last fall, I was out of town for 3 months, and the truck sat parked, though a friend did drive it occasionally.
<O
I use the Motorcraft semi-synthetic oil and change about every 7,000 miles. Before that I used Mobil1 full synthetic until it got so damn expensive. I think oil consumption is maybe half quart between changes, hardly noticeable.
Looking for expertise or opinions here. I would guess the incline and sitting for time may have contributed to this? What part or seal in the engine would be causing the startup smoke, and is this something for concern or not really? Thanks.

Mine too does that occasionally at cold start up, and I've got no other oil consumption problems. Only a small blow of blue smoke, then nothing. I would suspect is the oil ring is a little worn or just sticking a little until the engine warms up, letting a small amount of oil residue to remain on the cylinder and burn. After a few RPM, it seats and all is good. I'd leave well enough alone unless the oil consumption increases or the engine smokes under acceleration or continuously, meaning the rings are worn.

Last night I had to floor it real quick to pass some idiot and noticed some smoke in the rearview. This was about a mile after I left home with a cold engine. I am hoping to drive her another 2 years or to about 140K miles. Do I need to worry about this fouling the plugs prematurely? I think I replaced them at 75K. 96K miles now. Thanks for the reply.

Personally I change every 5000 km with a synthetic blend 5w-30 and my oil is a dark brown color everytime I change it. I don't like to see dark black oil on the dipstick.
To each their own!
