Important: Do not compress the lifter plungers using a vise or other tool. This will cause more air to enter the lifter assembly and will take more time
to bleed out once the lifters are installed.
16. If new lifters have been installed or the lifters bled down while the engine was disassembled excessive lifter noise may be experienced. This is a
normal condition and no engine damage is occurring. Use the following procedure in order to purge the air from the lifters:
16.1.
Start the engine and allow to warm up at the idle for 5 minutes.
16.2.
Increase the engine speed to 2,000 RPM until the lifter noise is gone.
16.3.
Return the engine to idle for an additional 5 minutes or perform a road test.
17. Start the engine and inspect for leaks.
