white smoke. engine bay. hmmm?

So it's been a while since i've posted an issue with my baby.

When it is cold(haven't drivin her in a few hours or more) i drive it down the street and maybe 1 minutes in white smoke billows out from my hood... then 2 minutes later the engine is warm and no more white smoke. its oil... i'm positive its oil because I add oil to her wayyyy to often. I thought it was a bad valve cover gasket... swapped it out and still white smoke. I have turned the car on cold and looked for smoke... it seems to becoming from the intake side... so i thought maybe just a loose oil filter... nope... um?? anyone else have a similar problem?

thx for the help

Re: white smoke. engine bay. hmmm?

What's it smell like? How often is way too often?

I wouldn't automatically assume oil. Most of the external seals are on the end of the engine, where the cam and crankshaft poke out, and a minute's worth of oil leak onto a hot exhaust pipe is usually followed by a fire (been there...). On the other hand, the heater hoses and the coolant crossover pipe are down underneath the intake manifold, and a leak in either would reach the hot exhaust pipe pretty easily. I wonder if there's a pinhole leak in one of the heater hoses, or a leaking connection to the core that swells shut as things heat up. Without seeing the car, that's just a guess, but it's worth checking out.

One other thought, from my own experience with heater hoses: sometimes they rot from the inside out. Squeeze the hoses in a couple of places, and judge if the hose wall feels thinner or more flexible in any particular spot.

Re: white smoke. engine bay. hmmm?

if its STRAIGHT up white smoke, that's burning coolant.

if its whitish/bluish, thats burning oil.

Re: white smoke. engine bay. hmmm?

it could also be your radiator cap. check to see if it seals properly.
