Size of threads in smog holes in rear of E7s?
- Thread starter 88 Fox GT
- Start date
They sell thermactor plugs which "plug" up the hole where the smog equipment goes (the same thing works for the front of you heads...you can get them at a Ford Dealership - part # F4ZZ-6E086-A or you can buy some from Summitracing - part # TFS-51400265...they work in the front of your heads and back of your heads and are meant for blocking the smog pump holes and letting your alternator and powersteering (on front of motor) bolts turn into your heads...
They are cheap and run anywhere from $2-8 bucks a piece...depending on where you get them...
It also provides for a much cleaner installation...

Well as long as your heads have a clean "screwing" passage they can be done by hand...but most likely you will need something like a screwdriver to put them in...you don't actually have to have the screwdriver above the T-plugs to screw them in...just do it from an angle...
Antiseize might help them slide in better...it shouldn't be a problem for you...

no you don't need a screwdriver.
they are a threaded insert...you can put a bolt into them and run them in w/ a ratchet. you don't need the insert (only on the front of the head sfor acc's)...so just leave the bolt in them.
another rig-job is to reverse the y pipe pieces..(if you cut them off w/ a hack saw)...left side to the right etc. ???
and re-bolt them back up...but the thermactor plugs are about 2-3 bucks each...so just do it right.

Or at least if you goto Ford you know what to look for.

The size of the thread is 5/8"-11. You can buy plugs at a hardware store, the only difference between them and the Ford parts, is that the inside of the plug isn't threaded. They have a hex for an allen wrench instead. This will not be a problem in the rear of the heads. The only time this is an issue is if you need to plug the front of the head and need the threaded hole. They are alot cheaper than Ford or Trick Flow, about $.75 each. As a side note, you will probably need to run a tap in before they will go in. The carbon can really build up on those threads. Why half ass it and use spark plugs?
88SC_GT said:well if you read my posts, i said i couldnt find anything to work. i can plug it with bolts i dont have can i?
it was either halfass it with plugs or leave them open. which would you choose?
Calm down...I didn't mean it rude...I was suggesting...if he can? Get the plugs...
Actually, I believe that was directed at me, about half assing it. Apparently you didn't try too hard to find the right thread bolt because a 5/8-11 bolt or plug can be found at any hardware store. They are not the same thread as a spark plug. I would never leave it open, I would do it right the first time, or just a temp fix if nothing else.
