This Zetec/ST170 aluminum oil pan has an internal oil baffle to ensure that the oil pickup never loses its oil supply to the pump. Our pan also is constructed with a .25″ (6.35mm) flange to help decrease the chances of an oil leak. Each pan also has a welded in 1/2 NPT bung that can be used for a turbo drain or capped if you prefer not to use it. This pan has a five quart capacity.
