My son took his 09 Silverado in under warranty because it was consuming oil and the first fix(in a long list) for this is changing the valve cover to one with an improved internal baffle.This is understandable but,they did something else which we don't understand.
They pulled the plugs and injected something into the cylinders which then had to sit for a day before he got it back.It seems to be OK as far as the oil consumption but, does anyone know what the liquid in the cylinder thing is all about...Mike.
