oil going into your intake deff sounds like you have a bent valve and the valve guide is broke(leaking oil threw the seal) or you have a blown HG, like you said, bring it to a shop. CMS is no longer doing service to new customers, only old customers and selling parts.(atleast the last I heard, I could be wrong) your issue is something any reputable shop can find and fix. the question is price, take a look at the 1st sticky on this forum for local shops and start making calls come monday. DONT drive the car!!! If your valves are bent you could possible drop one or a few valves if you continue to drive it causing MAJOR DAMAGE!!! So get help from a certified tech and be done with it.. G/L with your car man.. hope it all works out for you..... BTW the knocking sound comming from your camgear area further shows you may have damaged some valves causing them to become noisey..
