When I trouble shot a foam issue on one of our 850s, I found that the foam in the dipstick tube was very persistent.
There is a good chance that the foam was there before the oil change - did you check the oil level BEFORE the change?
When I tried to clean out the tube, I had to use several long pieces of chenille - a pipe cleaner type material used in crafting decorations.
I did get the tube clean and after several medium-length trips, the foam did not return. After a good number of short trips, the foam did return.
I think the problem was caused by the dipstick on the 5 cylinder engine being in front of the engine and does not heat up in cold weather.
