Engine Notes
1973 AUDI FOX - REPLACEMENT OIL SCRAPER RINGS - The following oil scraper rings are available for engines with high oil consumption. Note that two different types are manufactured: one type for early version Mahle pistons and one type for all KS and late version Mahle pistons. These differences must be noted because these two classes of pistons have different diameters for the bottom oil ring.

1973 AUDI FOX - NEW CYLINDER HEAD BOLTS & GASKET - All Fox models are now equipped with a new type of cylinder head bolt (Part No. 056 103 385 A), which is stamped "12.9". The torque values remain 54 ft. lbs. (7.5 mkg) cold and 61 ft. lbs. (8.5 mkg) warm. Also a new head gasket (Part No. 056 103 383 D), made of thicker lining of soft material, is used in conjunction with the new head bolts. These new parts may also be used to remedy cylinder head gasket leaks (use both bolts and gaskets, never separately).
1973 AUDI FOX - PLATE FOR CYLINDER HEAD COVER - From Chassis No. 32 037 204, two plates (Part No. 056 103 591) are used in production to install the cylinder head cover. These plates replace eight mounting washers normally used. These plates may also be used in earlier vehicles, especially in cases of cylinder head cover leakage.
