Ryan, given the problems you have had with your car not starting lately, i would not read too much into it. with all the cranking youve been doing, if your pulsing the injectors a lot trying to start it, you could be getting enough gas in there to bleed some down into the oil.
other causes are injectors staying on (bad computer relay).or bad o-rings on the injectors. you can buy new orings and pintles cheap. im thinking that if your fuel pressure regulator took a dump, you would not necessarily have enough pressure to run right (or start), and suck some fuel into the motor via vacuum lines (to the regulator). didnt think to mention that in your other thread. pull the regulator's vac line and see if there is fuel in it. sign of bad regulator.
good luck bud. know you havent been loving the car too much.
also, i meant to say on the other thread, as long as the spark looks decent, dont sweat it. when the car is not running, its cold out, and the battery is not really topped off, a blue spark is fine, in my experience. one thing you may want to check is that the plugs are not too fouled (if you are getting fuel. dont think you are). if you ever think you flooded the motor, put the pedal to the floor and crank it. this kills the injectors, clears the chambers.
good luck, Ryan
had the same problem with my car. but it was more like a 50/50 mixutre gas and oil. it would have caused a hydrolocked engine if i dicnt catch it. turns out the 42 lb injectors were stuck open spraying every cycle of the piston. The gas was passing right by the pisont rings into the motor. look into it, dont play it off or u may regtret it.
