Question

On a 01 L300  saturn V6  tried compression  test on 2/4/6 bank reads zero if u put your hand over intake runners  it pushes your hand off do I have bent valves even with the timing belt in time

Answer 1

The timing may not be in time you would need to check with the valve cover removed, , if the valve where bent you would not have compression out the intake, a recheck should done.
