MGB 5 Bearing Aluminium Sump Kit. Designed and manufactured by us for over 20 years.

This kit includes a baffle plate to suit the 4" /102mm diameter oil pick up strainer. If you have the larger 5" /127mm strainer fitted please choose the alternative sump kit that includes the 135mm baffle plate CM3311. This aluminium sump has been designed to improve heat dissipation, prevent oil surge with its cast vertical baffles and removable top baffle plate. The rigidity of the sump also has benefits for over bored engines, increasing the rigidity of the block at high rpm. The sump also has a rubber "O"ring seal instead of the usual paper gasket. This means less oil leaks and allows for easy removal and replacement. All aluminium sump kits include everything you need to fit the sump: Aluminium sump, baffle plate, sump fixing screws, baffle fixing screws, oil pump spacer, sump plug, sump washer and "O" ring oil seal.
