I am working on my nephews 2001 F-150 with a 5.4, I took the intake off to replace the dreaded heater hose from the water pump to the heater core. I was getting ready to put the intake back on and I was removing the few fuel injectors that stayed in the fuel rail and one of the o-rings fell down into the head, of course the valve on that cylinder is open and I can't get my shop vac to suck that thing out. Any ideas? I'm thinking if I can't get it out a blow torch might be fun!
