knocking after 3000rpms?

You seem to be operating under a misconception in regards to rod knock. It can and often does (especially when it's just starting the problem) only show up in specific rpm bands. It's not at all unusual for a GTE to knock in the rpm range you're talking about. Test drove a n/a once which did the exact same thing... idled beautifully, couldn't even feel it running. It even accelerated fine and was still quiet until a little over 3k rpm. Then I knew why the price on it was so great.

In a way you're lucky it's only in that rpm range, as it's probably not too bad at this point. Just don't drive it any more than you have to until you have it checked out. It's possible that pulling the oil pan and replacing the bearings on the #5 (or #6, can't recall) connecting rod will more-or-less fix it for you if you don't let it get any worse.
