Started the car & noticed a heap of white smoke from the exhaust. After a quick panic lol, checked the oil level...fine. Had a look at a small oil patch at the front pass side, bit more oil there. then I noticed the oil filler tube is loose! I could actually wobble it from side to side & see a small amount of movement in the gasket.

My question is...would this cause the smoke by changing crankcase pressure?
Also, does it have a gasket or just gasket goo which is what it looks like?

To the best of my knowledge no that wouldn't cause the smoke. You sure it's not condensation in the exhaust pipe? Check the coolant level too..

Is this persisting?

Any other clues?

I cannot imagine that Subaru would be so cheap as to use bog at the connection of the oil filler pipe to the sump. Sounds as if the top brace of the filler tube has also gone AWOL, perhaps?

Hope it is something simple ... :neutral:
 
Change your PCV valve.

A loose oil filler tube won't do it, but do check to see if it is loose.

I would wait for the next tank of gas and see if it continues, then we can go deeper. Check your coolant level as white is coolant.
 
If your engine was cold the exhaust system would be too - in these cooler months you get "white smoke" from the rear of the car. The time to be concerned about this is when the engine is up to temp and it continues. If it does you should be able to smell the coolant and notice a drop in your coolant level in the radiator.

If the engine and exhaust is up to temp and it's stopped it's perfectly natural. I've even seen water droplets pushed out of the exhaust on a cold morning, I'm sure I've seen Ruby Scoo do it as well. Cars run on gas do it more due to the water vapour in the exhaust gasses.

Let us know if there's anything to update on ;)
