TIP:
Pre-filling your external oil system will help prevent seal/gasket failure that may occur if attempting to "overfill" your engine capacity to account for your additional oil volume.
For convenience during pre-filling, you can put together this kit:
1x Fluid Transfer Pump from Summit Racing, Harbor Freight (or similar)


2x -8AN* to 1/2" hose adapters from Summit Racing (or similar)
*use -10AN fitting if using -10AN cooler lines and fittings.




Construct an in/out flow kit to aid in removing your old oil and pre-filling with fresh oil during service.
