cant figure out pecking noise
Hi,I have 1999 F-150 truck that has a slight pecking noise in it and it only pecks when I change the oil.after about 1000 miles just when the oil starts to get dirty it stops pecking,I have used lucas in it but it still does the same thing.So why does my truck run better with dirty oil and the pecking stops?
