Making progress on the E46! Replacing the entire cooling system, CCV system, cleaning and testing injectors, oil filter housing gasket, replacing all belts and pulleys, cleaning ICV, replacing all intake gaskets, and much more. Will probably split this up into several videos or it will be 5 hours long :)
Part 1 uploaded.
