Now that I've fixed my oil leak, it's time for a new air filter. So I went out last night to buy one, and when I took the old air filter out, I noticed fresh antifreeze on the lower air cleaner housing. It was nice and clean, like it had just come out of the bottle. I also noticed some antifreeze on the air cleaner itself, but only on the inside.
I had not run the engine for more than 15 minutes so it was not very hot yet.
Color me stumped. How would clean antifreeze end up inside the air cleaner housing, without passing through the air filter? The only other way air can get in there is through the oil breather cap, and I would expect any fluid coming through there to be dirty -- not clean and green.
Theories?
