I get a lot of smells like that - most in my case are coming from the breather filter I put on the motor when I installed the SC. I also notice a lot more 'wet' when crawling under but don't see it when checking fluid levels. My guess is that under certain circumstances fluids weep out of joints - not enough to produce real "leaks" but enough that the fluid is out and can burn against hot surfaces. JMHO.
