for a perfect oil cooling is the use of an external oil cooler along with the original cooler in the store the best solution. This adapter is mounted between the original oil cooler and the crankcase and has an additional power and input for the external oil cooler. This dual oil cooler adapter can only be installed if the original oil cooler in the store is like the single inlet engines t / m 7/1970 and there is a small adjustment to the store in order to make room for the oil outputs . Would this still mount engine after 8/1970 then you can not use the supplied gasket between the crankcase and the adapter, please refer to the gasket mentioned in options and use a cold store which is intended for a single engine inlet which there are also stated. Comes with 45 º oil hose connections.
