Thanks for the feedback Jeff.
Before you strip the engine it would be of great value if you could carry out a compression test, especially if you have the WPS 500 pressure transducer?
If not, using a conventional gauge would help and once we know the offending rotor we could then see how this relates to your test results. (Using the scope with an ignition sync as well as Pico diagnostics)
Below is a link to compression testing such engines with a conventional gauge and does contain some great pointers.https://www.youtube.com/watch?v=_jOLN-AGQO0
No problem Jeff if you have the vehicle in bits by now, I understand, take care......Steve
