Crank Lock pin access Cover
Customers may wish to replace this during timing belt replacement. This Audi VW crankshaft access plug and O-ring seal inserts into the drivers side lower portion of the engine block and is held in place with a 6mm bolt. This access plug is removed during timing belt installation allowing special tool 3242 (Crank Locking Tool) to be inserted into the engine block, locking the crankshaft at TDC. The plastic plug becomes brittle and has been known to crack during removal or installation, creating an oil leak.
