We continue the performance build for my ‘74 MGBGT Autocrosser. This time we are installing the oil pump and oil pan.
We discuss the most common mistake made when putting one of these engines together that leads to no oil pressure and requires subsequent removal of the engine to correct. We look at the oil pump, how oil flows through it, and how to check the clearances in it. We also look at potential oil restrictions within the casting of the new oil pumps and some minor modifications to reduce those restrictions. We then install the oil pan
