642 Heater plugs

[frankia2014]

Hi All, I am fitting a new turbo unit to my 2007 sprinter, three heater plugs do not work and have not for the last 2 years but when the turbo was removed I attempted to replace one of them, I soaked around the plug with wd40 and used a 1/4inch drive T bar backward and forward and then it turned very easy I think it is broken but I have not pulled anything out, so my question is will it stay there or will it blow out when engine starts

There is only one way to find out....

It will probably stay in. They usually do.
