The issue sounds like the timing belt is put on 180 degrees off making the exhaust the open when trying to start and the intake open when trying to compression. This will cause a vacuum sucking sound as the vehicle is starting. If the timing belt is on in the correct timing settings, then the head gasket is not set in properly and is causing the compression to escape. If you need further assistance with your engine sounds, then seek out a professional, such as one from Your Mechanic, to help you.
