With the machining complete, the block was deburred, washed, and blown dry. Before dropping in the sleeves, Demirjian gave the lower cylinders a light coat of Molykote O-ring lubricant. He also installed the three small O-rings onto a lower section of each sleeve and applied more Molykote O-ring lube. The O-rings are there to keep coolant from leaking into the crankcase, the same method used in wet-sleeve diesel engines. Loctite 515 flange sealant was applied to both prevent leaks and hold the sleeves in place during decking and boring. With that finished, the sleeves could then be slid into the machined block. The sleeves are significantly stronger than the original block bores and are constructed out of the same material used in Darton’s Top Fuel and Funny Car applications.
