Schwanke Engines offers a secondary sealing program. The sealing program should be implemented at pre-season teching and used as a tech aid throughout the season. It is recommended to also include your track or sanctioning logo (initials/words) on the seals. The program is implemented by the use of sequentially numbered seals that can be installed on the valve covers, timing cover and intake manifold. The seals are available in minimum lots of 100. Call for orders more than 100 for special pricing.
