Volkswagen Air Cooled 1949-1969 Repair Guide

Oil Strainer



The EPA warns that prolonged contact with used engine oil may cause a number of skin disorders, including cancer! You should make every effort to minimize your exposure to used engine oil. Protective gloves should be worn when changing the oil. Wash your hands and any other exposed skin areas as soon as possible after exposure to used engine oil. Soap and water, or waterless hand cleaner should be used.

All Volkswagen models are equipped with the same type of oil strainer. The oil strainer can be easily removed simply by removing the restraining nuts, washers, oil strainer plate, strainer and gaskets. Once taken out, the strainer must be thoroughly cleaned and all traces of old gaskets removed prior to fitting new ones. The suction pipe should be checked for tightness and proper position. When the strainer is installed, be sure that the suction pipe is correctly seated in the strainer. If necessary, the strainer may be bent slightly. The measurement from the strainer flange to the tip of the suction pipe should be 0.35-0.43 in. (9-11mm). The measurement from the flange to the bottom of the strainer should be 0.20-0.28 in. (5-7mm). The cap nuts at the bottom of the strainer should not be overtightened, for the bottom plate may become distorted and lead to leakage of engine lubricant. If it is desired, the strainer can be equipped with a permanent magnet designed to retain metal particles that are circulating in the oil. This magnet is held in place by means of a spring clip, and should be removed and cleaned whenever the strainer is removed for the same purpose. Magnetic drain plugs are also available.
