So i try to drive it home and it keeps dying on me and the tick is really bad. My first thought was that a lifter had collapsed but i replace all 16 and it's still doing it. it idles almost normal, oil pressure is good, doesn't overheatstarts right up still.. anybody know what this could be? i posted a video with sound above of it.

P.S. - the "smoke" you see in the video is just oil burning off of the exhaust manifold. I was running it with the valve cover off at first trying to find the noise.
