Hi 5.7GSI PWTR Engine Misfire new plugs wires and cap all plugs normal except number 6 loaded with carbon. When I started it up to warm up for compression test had lifter noise for about 20 seconds and then went away and misfire didn't start at first as soon as temp gauge started o move. Engine doesn't have a lot of hours on it. So test results were all at 160 except 6 at 150. What could cause the miss? Stuck valve or not seating? Are valves adjustable? Anything else it could be? hanks
