Oil primer tool for "pre-lubing" engines. Rebuilt or "New" engines typically require a lot of cranking to build oil pressure which is not good for engine internals. With this tool you can turn the oil pump and build oil pressure without rotating the engine. Great for building oil pressure on an engine stand to check for leaks and look for proper oiling at the camshaft . Uses a 10mm hex head for turning the tool. Fits all Nissan "L" series 4 and 6 cylinder engines.
Requires removal of the distributor, oil pump and distributor drive spindle to install the tool.
