if i recall correctly only the svtf has the plug.
of course my plug leaked, fixed that, then the housing cracked awhile later. ordered a new housing, the wrong one was sent. the plug hole was molded shut and so was the top sensor hole. i modified it and drilled the top sensor hole and used a coping saw to cut the grooves for the sensors keeper. no more worrying about the plug leaking! altho the sensor was a pita, the old oring fit loose, but a new one went in snug. i can get the housings part number if anyone wants and do a writup on how to mod it.

add everything but the part about "having to smackit with a hammer" and "pry it with a handle". IMHO that is not an o-ring to begin with. But if you're gonna use one grind or shave a flat edge so you don't split the housing.

I just went to Ford today and bought a new Thermostat housing for my 02 ZTS. It only cost me like $58 I believe, and it no longer had that plug. Where the plug should be is now a solid piece of plastic I guess.
I'll do the exchange either tomorrow or over the weekend and I'll write a little about what I found.

I need one of these o-rings any one know where to get one, and/or the part # ?

That plug is in the svt's, i believe the regular zetec have a sensor in that hole. I can get you a new plug with the o-ring for $8.

The Ford O-ring will just go bad again.

I found it easier to take the housing off the car. I put it in a vice, to squeeze the plug back in. No cracks, no leaks.

I made up a webpage for the info regarding getting the o-ring replacements. Quite a few people have asked for Priority Service and that is now available.

I have this problem now and am wondering if this would cause problems such as oil gettin into the top of the motor and fouling out the plugs? That is what is also happening in my motor, along with the coolant issue. thanks in advance

yea, oil could foul out your plugs in theory, but I doubt its related to the thermostat housing gasket/O-ring. Not sure how you've come to that conclusion or even speculation...

Oil leaking into your engine could foul up alot of things...but when this O-ring leaks, the coolant is leaking down onto your engine, transmission and a couple other places, but eventually the ground. Its not getting into your engine unless you have a coolant leak somewhere else.
