why does my number 3 spark plug keep burning off?

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

when the car was bought that was done after the first time the plug blow out. I forgot to mention this was the 2nd time this has happened. The port less then 8 months old?

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.

we have down that already.

sorry that is already done. somebody said a stuck intake valve

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.

dont think your understanding me, o took it to the shop today, they told me that its some kind of injector getting to much lean of fuel.

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?

the actual problem is that i can make two trips from my house to walmarts which is just 5 minutes away and my whole bottom number 3 spark plug is burnf off. its only blew completely out the whole once.

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

okay, i am going to have it put on a machine today

took it to shop, cant tell me whats wrong with it

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?

yes thats what i sayn.

yes thats what i was sayn, i tok it to another place they say Cylinder compression

your using platium plugs right.replace the wire and plug.nothing in compression will cause this.
