Have a 2007 cx7 bought new turbo from amazon turbo is bad had great power lose after 100 miles when giving throttle on highway I hear a hissing noise and then sound like something trying to lock up like turbo locking up. Pulled over and oul light came on at idle this is a new rebuilt engine with maybe 300 miles on it. So my question is can a blown turbo cause low oil pressure and light to come on

 

I've tried to read your post a few times and cannot make out what you're describing and asking. Can you restate your ask?
