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!

 

tell a crackhead that a crack rock fell down there....
Other than removing the head... I got nothin....
good luck...!!!!
maybe pull the spark plug and shoot a crap-ton of compressed air at the same time the vacuum is on the other end...
again, good luck, I definitely do not envy your dilemma...

 

I would not worry about a small rubber o-ring that fell into engine.

 

^^ plus one a small rubber O ring is nothing to worry about.

 

Thanks guys. By the grace of God and a little luck I was able to get the o-rings out with a flexible claw tool I found at Advance auto called flexible mechanical fingers. Best $6.99 I ever spent!

I you can't get it out, remember that it will burn up within 5 minutes of running. I doubt that there would be any residue to cause problems because of the heat and compression. It most likely would blow right out of the exhaust port as soon as combustion hits the cylinder and the force should push it right out.

I've watched gasket material blow out of a straight pipe, when it was on the stand running. If it was a metal item, I'd worry, but in this case, I doubt anything could or would happen.

 

Yeah, just let it roll. It will be gone before too long.

 

Ya'll need to stop skipping over posts. He got it out
