it being a CM870..
was it the bubble test that you did, with the test plate?.

just making sure... as it is not really considered a 'leak-down test' for the older engines. It is more like an injector leakage bubble test instead. It has to be done mechanically, using a proper block plate where the actuators mount and checking for bubbles in a glass of water while cranking the engine with the ecm power connector unplugged, and not by using the Insite software.

(just confirming, thats all).
