Leaking pushrod tube seal? These seals are simply the best. Made out of viton, which resists leaks and withstands heat far better than normal seals, or the seals that come in rebuild kits. Two sizes are required per pushrod tube. The smaller seal for the side closest to the block, and the larger size which seals to the cylinder head. The larger size can be found here.
Sold individually, 8 required per vehicle.
