I have an 2001 F-250 5.4L. It has the Triton engine and the problem with spark plugs blowing out. I have a kit with thick inserts that I'm going to install. I need to drill and tap the heads, but first I need to get the piston in the cylinder I'm working on to get close to the bottom and have all the valves shut. But I can't manually turn the engine over. I tried using a long ratchet with a socket that fits the nut on the crankshaft pully, but the nut just seems to tighten more, instead of turning the engine over. And trying to turn the fan pully doesn't do it either. Also, using the electric start for a split second at a time still seems to turn the engine over too quickly for me to get the piston where I need it.
Do I need to pull all the spark plugs to do this? I really just wanted to work on one cylinder for now, instead of opening up a can of worms.
