2007 mini cooper base model: vacuum pump seized up during start up. My mechanic replace vacuum pump and then try to start car. Car would not start. Mechanic check timing. Looked as if the pump seizer caused the cams to move out of time (car now out of time). Mechanic adjusted timing. Car still won't start sounds total different (like it has no compression). Compression Test: no compression all four cylinders. Leak down test is holding air on all four cylinders. Any suggestions on what could be going on with this mini??? Thanks
