S&S, oil control valve. For oil cooled M8 engines

The OEM 62700141 and 62700141A oil control valve (check valve oil pressure), used on all oil/air cooled M8 engines in the front right side of the crankcase, regulates the amount of oil flowing to the oil cooler/heads. The stock assembly includes a check ball retainer that is formed steel. Over time this retainer can fatigue and break, causing chips to flow through the oil and cause engine damage. The S&S oil control valve is constructed of 6061 billet aluminum and the check ball retainer is machined from high strength steel for long-lasting durability. Easy and quick to install.
