spark plug blew out!!!!!!!!!!!

I have a 99 F250 with the V-10, a sprk plug blew out of the head today, I found a kit to repair the threads, it says I need to remove the head, If I use some grease on the tap, do I NEED to remove the head, and how successful is this? and what do I need to know?

I had a 02 F150 that did that, I carried to a local shop and they repaired mine without removing the head. It did not take them very long. I do not know how well it held up because I traded it the next week for the F250 that I had wanted.

It does not look like a big deal to fix, why does everybody act like it is?

Agreed...The expense to repair this type of problem should be on Ford's nickel. Completly unexceptable design!

It depends on how you look at the problem.

Earlier years of 2V engines had a design flaw where there was a minimal thread count in the spark plug hole. The engines (4.6L, 5.4L and 6.8L) blow out spark plugs more frequently than other engines.

Having said that, you also have to realize 2 things

First, that the majority of these engines will not blow out spark plugs. Why do you hear about it so much? The reason is because owners do not complain that their spark plugs didn't blow out

Second, that the spark plugs usually blow out AFTER the plugs have been changed (which is a strong indicator that perhaps the procedure for changing the spark plugs was not followed properly).

the torque specs!! and have a good torque wrench on hand to seat them. with taper seat spark plugs, your margin for error is very small when it comes to getting it right... and it's very important to get it right on our motors.

i've had 2 blow out on me so far. job isn't hard, just verrrry nerve-racking, in fear of dropping aluminum chips into the heads or not seating the insert correctly (talking about a repair w/ head on obviously). you can do it, just be careful and take your time.

I did the spark plugs on mine and never used a torque wrench, just used a ratchet.

You guys are starting to make me worry!

i did too. the first plug that blew went before i changed the plugs (not sure if they were changed before i owned it), then the scond one went out earlier this winter. i changed the plugs last summer.

it's kind of a pain in the rear to get to the rear plugs, but it's probably worth half a saturday to go thru and check them all with a torque wrench... that's what i need to do. beats fixing a blown one!
