Engine knock
I have an 04 Tahoe z71. Engine code z (flex fuel). I changed the oil today and after driving 20 miles on brand new mobil1 5w30 and a Bosch premium filter I have loud knocks coming from the bottom end. I owe a lot of money in taxes and a baby due in April. Does anyone know why this is happening...- Kenny801
