Hi everyone. So, I'm attempting a valve stem seal replacement on a 98 qd32 engine. Rockers are off, glow plugs out. I drop a screwdriver in the glow plug hole, rotate the crank and absolutely no movement of the screwdriver. Am i missing something? I intend to do the rope in the cylinder method to prevent valve movement while the valve springs are off. Do the injectors provide a better entry point? I'd rather not have to mess with fuel lines etc. Any help would be most welcome!
