RCM 13 Piece Billet Block Blanking Kit. When using used blocks for rebuilds, we use a cleansing process that brings these blocks back to life. This RCM kit ensures that the bungs not only seal correctly but that they look as good as possible. Each bung is individually anodized in our gloss black, before having the RCM Power Parts laser marked into place. New aluminum sealing washers are supplied for each bung.

The modine water adaptor is manufactured from stainless steel, ensuring that the problem of the OE part rusting and corroding is completely removed.

The oil pressure switch bung is included, along with the 2 plain block sealing bolts on top of the block.

This 13-piece kit also includes the RCM Billet Gudgeon Pin Cover and Oil Separator Cover, completely replacing all the OE sealing bungs with RCM Billet versions.
