I recently installed injectors in my LB7. After starting it, it hazed quite a bit(White smoke out the tailpipe). I drove it for a while hoping that it would burn off. Smoke ended up getting worse and had fuel dripping down from the engine. Didnt look real close at it cause i was short for time, but i couldnt see any signs of lines leaking on the top of the motor. Any ideas what might of went wrong. Pressure in the oil pan, etc..???

Well white smoke as you describe is unburnt fuel. Were the injectors GM reman replacements? Sounds like one or more are dumping fuel. If the fuel you see leaking is in the front of the motor could be the crankcase vent as your oil is being diluted by fuel from the injector.

Do a wick test and check balance rates for starters would be my suggestion.

Yeah they are GM remans. I'm almost positive there is fuel in the oil. The fuel dripping down is discolored and feels like an oily mix. Ill check balance rates and see what I can find. Thanks.
