Hey I'm Michael Richey
I'm working on a 2010 Chevy Silverado z71 5.3 lc9
A lil over a year ago it started missing traced it down to a flattened roller on a lifter so I put a stage 3 Texas speed low lift cam package in it off of Michigan Motorsports cam with 7.400-0.80 push rods, springs, lifters, an cam changed the valley pan it started an ran great for about two weeks an died an now I only have compression in cylinders 1 an 7 with the push rods out? I pulled the heads off I do not see any bent valves or push rods , there's metal shavings in the intake ports on the heads and intake an it doesn't look like the valves have slapped the pistons in as a loss plz help
oh an before I pulled the heads I could turn the motor over an ounce I would stop a few of the springs would start clicking/popping like they wasn't released fully? The valves look to be seated correctly looking at it after I got the heads off
