F250 Spark Plug Blew Out

I know nothing
A friend of mine has a 2003 F250 with the 5.4. It stripped the threads on the head when it blew. Can a Heilcoil or a TimeSert be done without removing the head. The plug that blew in on the passenger side, second from the front. Thanks, Curt

Yes, that is the recommended repair.
 
There is a knack for doing the inserts.

Make sure he pays attention to what he is doing when he does it.

It is a really good idea to use a healthy dose of grease when doing the insert as it keeps the waste from the threading from going down onto the top of the piston.

True and also you will need a shop vac. I used the timesert kit with great results
 
Who is the brilliant Ford engineer who thought that 3 threads in an aluminum head are plenty for a truck motor's spark plug?
Talk about creating a TON of bad will among your loyal customers!...:shake:
Good luck with the repair.
Unfortunatley, most Ford mechanics are experts from repetition at doing the repair.
 
We see this all the time at my dealer, what were doing is making sure that we keep as much metal out of the cylinder and install new threads, shop vac and a bore scope will help, its kinda skitchy but i havent had one come back so there holding... on a stock motor lol

We have done some on higher hp applications and they seem to survive.
