ok i have been having some different posts on some of my problems with my car. recently i finally pulled the fuel rails to check for injector leaking.. i noticed right as i lifted the fuel rail up slightly that the #8 injector poured out some fuel and the little shim piece on the bottom was cracked loose kinda.. i tried turning the key to on and checking them then and nothing happend from then on that i could notice.. i only noticed a decent amount of fuel at first on that one injector.. after that nothing seemed to be dripping or anything.. i took one injector out to inspect it just to see how bad they looked and i noticed some white color stuff coming from somewhere not sure where but it was a pretty bright white color after i took the injector out.. i would just like to know if what i found wit the one injector is enough to have been causing fuel to enter my oil this whole time? everyone was saying before to check this and this is al ive found.. ive also been lead to other problems such as some white smoke coming from what i think would be a head gasket.. and that only started to happen from the car sititng this long.. im going to change my oil tommorow and see wat its like and put some fresh stuff in for now but would like to know what to do next.. thanks
