So i crawled under the car this morning to see what was involved in changing out the primary and secondary O2 sensors and I find this - see photos. Is this cracks in the oil pan? There's no oil seepage coming out, but what the heck? Thoughts?

It's nothing, just casting marks since it's a cast aluminum pan, most newer cars come that way where older had a pressed steel pan, like my 4g for instance.

ive seen this a couple times before, its called "crank crazing," this means your crankshaft is turning so fast that it gets too hot and actually causes the fragile aluminum of the oil pan to start getting those distinctive hairline cracks. this usually only happens to peoples cars who put too much stress on the engine. you need to search ebay for magic gas economy pills, add this to your gas tank next time you fill up and you should gain about +5 mpg and some extra horsepower. slowly your oil pan will start to fuse back together from the natural heating and cooling cycle and look much more smooth.
@bouckarooo and @minilogoguy18 yeah you're right.. I was underthere alot today trying to break the O2 sensor loose.. decided it's nothing.. but I may try that magic gas pill the @wrathofshampoo is talking about.. damn I need 5 more miles a gallon LOL!!!

or you can pick it up at your local auto store, next to the vtec fluid and 710 cap....
