I’m replacing spark plugs on my 6G75 and since it requires removing quite a few parts, cleaning everything at the same time.
So far cleaned intake manifold itself and all its ports (as much as I could without disassembly, thinking of getting a pressure washer tomorrow as I’ve spent fortune on carb cleaner bottles already), throttle body, EGR valve, PCV valve (will replace, forgot to order). Checked butterfly valves and screws - all good there. Going to clean MIVEC valve tomorrow, haven’t checked if it’s easy to remove yet. What else is worth checking/cleaning while the intake is removed?
