    How to adjust valves on a mack without markings on flywheel

    okay thanks for your reply hear me out I found the markings the fly wheel jus needed sanding , but I notice my 1&6 mark are about a couple degree away from the pointer on the bella housing when the engine is at tdc or one clutch hole away from the pointer ,what I want to know is do I adjust the valve lash at tdc or work with my markings 1&6 ,2&5, 3&4 and I know that I have to adjust on compression stroke using firing order .(note i took out an injector and incerted a screwdriver in the hole to find tdc )
