Why does my number 3 spark plug keep burning off?

The plug port is crossthreated out-try using heli-coil

You will have to get a helicoil inserted, this is a new stainless steel thread insert, the head should really come off to to this as it requires re drilling the plug hole over size and re tapping for the insert.

If you have already done a helicoil and it is still blowing out, I feel that the hole is to big now and the head will have to be replaced.

No I don't, first you say that the spark plug blows out you say it has been helicoiled and it still blows out now it's a fuel problem. What is the actual issue here?

This was the posted question.

I leave just five minutes away from work, and just from work to home my recently new number 3 spark plug blows out of it's casing. Poofs of air now come out of its place?

I would look for vacuum leaks at the cylinder and have that injector removed and tested.

They probably tying to scam you-what's yourself-go to a different place

Your saying when you remove the plug. The bottom where the ingntor and porcline is burning off?

Your using platium plugs right. Replace the wire and plug. Nothing in compression will cause this.
