New plugs I bought only had half-thread as well. I researched it VERY WELL before I installed them and found out they never thread into the non-threaded part anyways like Chris said. BTW Chris, very witty to change your poster status to "newbie" LOL
I dont know what causes the spark plug blowout, but we always wind up pulling the heads and getting a machine shop to drill and install threaded inserts when we repair them. I usually see it on trucks and expeditions, but I have seen it on a Mustang once. I like to just snug the plugs down. You dont have to show them who the boss is
I have seen 2 different PI-headed vehicles blow out the plugs so I would suppose they have the same 3 threads holding in the plug. In the SHM book it says the SVO heads accept only a fully-threaded plug. The blow-outs always seems to be on the right bank too. I think every one I have ever seen was on the right bank.
I dont know about you, but I would rather yank the heads than risk running metal shavings through the cylinder. I always let a machine shop handle mine after I have removed them, although in the SHM book they talk about installing inserts without pulling the head, which probably would take some balls.

The one thing I wasn't sure about was that it instructs you...

I am in need of some guidance regarding a recent engine swap in my 97 bird.
The back story:
It has been quite a while since I have posted, mostly due to the fact that my motor exploded roughly 6 years ago. Since then the car has...
Hey guys, I was wondering if anyone could tell me for sure if these spark plug wires only fit DOHC applications or if they'll also fit my SOHC:
I have a 97 Thunderbird that still has the old modular 4.6 SOHC and the wires I got a...
Okay, so two years ago I got the P1443 and replaced all the evap hoses with fuel line and both electrical parts. I should say, all but one hose, the one closest to the fuel tank. I was pretty sure I could get that one off, but not sure at all I could get a new hose on there because it looked...
