Replace the cylinder liners and pistons as a best practice. This will help reduce emissions and increase car efficiency.
Remove and dispose of the old diesel cylinder cap. Apply an LPG modified head to the cylinder on the engine. Screw the cap into place on top of the cylinder and make sure that it is secure.
