RS Turbo with a Loose Rocker Arm Waveform Notes

In the above waveform, the FirsLook sensor was connected to the inlet manifold and to channel A on the oscilloscope. Channel B of the oscilloscope was connected to the number 1 plug lead.

The RS Turbo had a loose rocker arm for cylinder number 1 which meant the exhaust valve wasn’t opening at all. The exhaust gases were then expelled into the inlet manifold as soon as the inlet valve opened. This can be seen quite nicely in the waveform.
