I can tell you that I was the same issue and kept trying all the cheap little fixes and I went on a road trip drive 480 miles, pulled into my destination and went to crank it the next morning and all hell broke loose. The #7 cylinder slung the follower to the side which then broke in half then one half blew a hole in the piston went into the crankcase turned into a pinball and just destroyed the engine. Got a crate motor and swapped out the followers for the ones with the new design. Just be mindful and don't do like I did and try every trick possible avoiding opening up the engine. I would take it back under warranty.

First off, thank you for all of the replies. I found the culprit and honestly, I’m quite embarrassed. I pulled the intake to checking wires for a break but no luck. I also wanted to verify that my “helper” got the vacuum line from the brake booster to the intake connected. Everything checked out and I was back at square one. When I grabbed the intake to put it back on, I found a shop rag blocking cyl 7. A FLIPPING SHOP RAG. I can only guess that when I covered the intake after removing the throttle body, the shop rag fell down and I didn’t notice. I always cover up “holes” that will swallow up a little bolt or nut. I am paranoid of dropping something into the engine. Lesson learned the hard way. I’ll use tape next time. Then on top of everything, I cracked the stock mani when I was torquing it down. Cyl 1 by the coolant cross over. But I still started it and it purrs like new. Wait. It is new. Oh well. I’ll order an after market intake tomorrow. Thanks again everyone.
