bang bang bang
hey guys, got something for you to nut over for me.
my motor is doin things that have me scared during idle it runs perfect but it has a repeated bang. its 8 months old. i thought it was misfiring so i bought new leads checked plugs they are clean.
i have been told from listening to video footage it is the exhaust valve possibly staying open.
i havent checked compression but that will be done shortly
the thing that has me twisted is when i unplug No7 it runs nice, plug it back in and it continues banging??? whos knows why
i've taken the pushrods out form 5 and 7 and they straight with no damage and the valves are moving freely.
any ideas guys
