Ok, a little bit of history on the engine. Car has livernois stage 3 ported heads and comp 127500's. it had comp .600 lift springs with comp titanium retainers and vct limiters. Engine was taken apart due to oil burning issue. Livernois put 3 small holes in 3 intake ports when they ported my heads, which they covered under warranty. Prior to engine coming apart it never once made any type of noise, ran and idled great. When new heads were reassembled Livernois put there .600 lift spring on the heads because they said the comp ones varied to much in spring pressure and put steel retainers in because they said mine were not titanium because they were magnetic. Also had different timing chain guides on it because one of mine was cracked. Reused original timing chains, tensioners, vct, vct solenoids, followers and lash adjusters. Car has 62,XXX hard miles on it.
This noise is intermittent, the car was running and driving about 20 minutes prior to making this noise. It will come and go. When i first heard it, I was bleeding the cooling system, car had been running about 15 min when it all of the sudden did it after a slight rev. I freaked and killed the engine and pulled passenger valve cover. Every thing looked good, all followers had equal tension, i disabled fuel and spark and turned it over lash adjuster were pumping oil everything looked good. Only thing i noticed was timing chain tensioner was moving back and forth a bit as engine was cranking. Did not know if this was normal? In video it sounds if noise is in middle of valve cover but some times it sounds like its at the front. With a stethoscope you can defiantly tell its in the front half of the valve cover. My guess is a bad timing chain tensioner. I left them extended for months, should of put a small clamp on them. I'm open to all opinions! Sorry for the book, just wanted all the details out there. Thanks guys!
