04 sedan with 155,000 miles SRI and cat delete header. well earlier today i heard a ticking coming from my engine, so i took off my oil cap and sure enough it had milky looking oil all over it. checked the dip stick and its dry. looked under the car, the passenger side wheel, and under the crankshaft pulley was covered in oil. (before this my engine had no leaks) so obviously all my oil has leaked out somehow and coolant got in my oil. i haven't had time to dig into it but it is an unwelcome Christmas gift. i will keep you guys posted
