One of our most popular items is this precision cast alloy deep sump for the Triumph 6 cylinder engine. This is a direct bolt on replacement for the standard pressed steel item, which is vulnerable to damage from stones after years of use and also does not offer much in the way of stiffness to the base of the engine block, and therefore importantly the area below the rear engine oil seal assembly which tends to be the main point of oil leakage on the engine.

This is a die cast item as opposed to the traditional sand cast process. This ensures that the general appearance is better (although the cast finish is preserved) and the fit is also significantly better and tighter. The sump kit comes as you see it with a horizontal windage tray which is a press fit (although it can be bolted into place if necessary), two steel bungs pls washers for oil draining (front) and an oil temperature gauge (side).

We can also supply a bolt kit and sump gasket if necessary as additional items at extra cost. The engine securing bolts are slightly longer owing to the depth of the lip of the sump  (about 7mm more than the standard steel item). A standard sump gasket can be used and our experience is that this is adequate.
