lt1 initial break in , oil is black
ok so the first time i ran my motor the tune was for stock injectors and i have 30 lb so it was running rich. i now have the correct tune and new o2 sensors and ran the motor for a little bit today trying to trouble shoot and i noticed that the oil is BLACK. is this from the previous incorrect tune? did i do any damage?
tomorrow i plan to change the oil and put fresh gas with octane booster
also , it is throwing codes for MAF and TPS.
