Thank you for pointing out several thoughts. It was several months ago that I tested the switchover valve and overload protection switch.

I have not tested the wastegate control servo yet, will do today!

I have a service manual printed for everything related with the turbo and will test everything I can.

I didn't notice anything you mentioned about "intermittant resistance" with the turbo compressor wheel, it turned freely.

I'll report back my findings tonight.............Steve
