My husband doesnt think its the head gasket. Are there other possible reasons for the smoke?

I had a 1.8T in the shop last week with a stuck open injector... raw
fuel was coming out the tail pipe while the engine was running.

White smoke accompanied the raw fuel.

Replaced the faulty injector and all was good again (once the exhaust
cleared out).

Wasn't smoking as bad as this Diesel with a faulty Injector:

mkidd4, over the internet diagnosis might not pinpoint what is
wrong with your.

Comparing spark plugs, looking inside the cylinders with a borescope
and smelling the smoke might lead to a better "guess" as to what the
problem might be.

Good luck.

Incomplete combustion in a diesel will produce white smoke, this will normally be associated with a misfire the smoke will smell very fuley, check this first.

Sorry... I'm not saying that raw fuel is the problem, I was just
saying that white smoke isn't always coolant.

The fact that the white smoke only occurs during hard acceleration, might
make this more difficult to track down, as it does not happen at idle (where one can sniff the exhaust).

Does anyone think it may be stuck rings?

Have a leak down test done to determine.

What engine is in the car?

If 1.8T, check the PCV system for correct venting... if the system
pressurizes too much, it could force oil into the intake that
then gets burnt all of a sudden.

Small amounts of oil / vapor is normal, but if too much makes its
way into the intake, smoking will take place.

Again, checking spark plugs might point to oil burning.

I had a 1.8T Passat in the shop yesterday that blew white smoke under boost.

I drained close 1 liter of oil from the intercooler. Further inspection found that the
turbo shaft had too much play, allowing oil to leak into the intake.

The oil was collecting in the intercooler and forced into the engine under heavier
loads / acceleration.

A new turbo solved the smoking issue,

I am in the process of making a youtube video on turbo replacement... will post
the link here once I have finished it.

Have you since solved / found your smoking issue?
