In the second and third parts of this video, we will measure valve spring pressure. We begin in part 2 by measuring the valve spring pressure at open valve. Also known as the valve spring pressure at maximum valve lift. In part 3, we will measure the valve spring pressure at installed length.
The first thing to check is whether the valve springs have the correct specifications for your type of engine. The VW workshop manual recommends measuring the spring pressure when the valve is fully open.
In part 1, we will analyze the operation of valves and valve springs, and explain why valves can float.
In part 2, we will measure valve spring pressure at maximum valve lift.
In part 3, we will show how to measure the installed length of the valve spring, and measure with how much force, the valve is pressed onto the valve seat.
In part 4, we will perform a visual inspection of the valves, valve springs, valve spring retainers and valve keeprs, and discuss specifications.
