Sounds exactly like you've got an air leak did you renew the gaskets?

id agree with the above

Did you shorten the alternator bolt?
It will sit wonkey and won't seal.

what corsadonk says
dont know if its a problem with the fakes, but that bolt gets in the way of the proper mantzels. carb cleaner will help you find the leak
