Roller lifter conversation

The problem is the chamfer on the lifter bore is wildly all over the place. Some deep, some not. It could uncover the band on the base circle also. The worn bores are what they are. A bunch of oil pressure is lost there. You can measure how worn they are then decide if it is acceptable. You would have the issue roller or not, so if the block had good pressure before…, but measure is the only way to be sure. Ignoring wear, you can install the cam and each lifter and see if the oil band gets uncovered. Both sides. Base circle and max lift. It can be hard to see. You NEED to look at every lifter. The chamfers are NOT uniform.
