white smoke at start up and during the run


Recommended Posts

Hi Jeff,

I was with the group on Sunday meet. I remembered you told me, the problem is normal. It is related to the oil separator...

I jacked the car up and noticed some oil leak (little) on the passenger side. Should this is the cause of the smoke?

So far, there is no CE light and the car is running fine

Can this be the Oil Filler Tube problem? Or the air/oil separator goes bad?

Thanks,

-Nat

I said it might be a oil/vapor separator starting to go bad. At least I hope that is what it is or somethning simple like that, since I was told you missed a downshift and you could have bent internal parts - but when I saw your car it sounded fine.

Is it still smoking.

The oil could be from the oil filler tube or the camshaft cover since the is the most common source of leaks. You will have to clean everything and see where it is comming from. I sent a guy the instructions on how to replace the tube and he did it - that was posted a few weeks ago. This would not be related to smoke out of the exhaust.

Some info on the oil separator. Hope that is what it is but that shift bothers me.

Thank you very much for the info, Jeff.

Actually, I did not miss the gear (down shift) during the run.

It must be one of the things that you mentioned above.

I had the camshaft cover on the passenger side work done 2 months ago.

They replace the black round cones between the spark plug and the gasket.

It must be the oil filler tube. I will track it down and let you know.

So far, I have not seen any smoke.

Cheers,

-Nat

P.S: I still own you the making of "Removing the front bumper" :-). I will be your "star" for the next "working on car" event

I talked to the guys at the shop today.

1997 and I think 1998 had the old horizonal vapor separator - that is what my 1997 has. If the car is on angles you can get oil into the intake and not a check engine light. This is why Porsche switch to the new vertical design. If the old style needs to be replaced it is replaced with the new vertical.

When the separator fails is fails, and does not cure itself. When it fails you see constant smoke out the tail pipe, or pressure out of the oil filler tube. Smoke is easy to see, so the other test is to remove the oil cap and see if there is pressure.

So if this is the reason for your smoke on the track then you must have been going faster than me.
