What is the 111-198-029 Seal Kit?

Volkswagen engine cases through 1969 came with small oil galleries and single relief oil systems.  The original oil coolers installed on these engines used the 111-117-151 seal shown in the listings above.  With the introduction of the dual relief cases in 1970,  the oil galleries where enlarged and a stepped seal was introduced to install the small hole oil cooler onto the large hole case.  As time went on, Volkswagen eventually upgraded the replacement cooler with the larger holes, but now it required the same stepped seal to install it to the early small hole case.  Seal kit 111-198-029 comes with two of these stepped seals and they must be installed as shown below to prevent leaks. The same applies when retro fitting a Doghouse style cooler to an early small hole case.  How do you determine if you have a small hole case? Check the engine number.  Bug B5 000 000 cases, Bus B6 000 000 and all engines beginning with 2 letters (AB, AE, AH, etc.) are usually dual relief, big hole cases.  All others are usually single relief, small hole cases.
