0012M fix completed

[rp23g7]

So, i finished my 0012M fix yesterday, well most of it.

I replaced the upper and lower O rings, kinda puzzled at Ford, dont see any reason they actually make the intake manifold in two pieces.

Both sets were rock hard, and you could see on the lower where it was leaking through the seal. Sorry, i didnt take any pictures.

I didnt replace the tensioner, as the part looked completley different, and i didnt want to take something apart and find that the part wouldnt work.

The factory one has a hex head on it, the replacement in the kit had the hex and then the machining extended another inch or so above, it looked like it wouldnt clear the temp sensor, i did however put the restrictor and the new plug in, that seemed to really help a lot.

Put everything back together and it idled like crud, looked for something i forgot, turned out i didnt reattach the PCV hose to the back of the manifold.

Took it for a drive and it ran and idled really good, had to wait till morning to see if the fix worked though.

Started it up this moring and it started and idled by itself. I dont ever remember it not doing the high rev at startup, and we bough it new.

Congratulations!

I'm glad that there were no complications and that now your Explorer is running right! Thanks for the update.

RP23g7, if you bought it new, did you not get the owner notification for the 0012M update?

the screw in tensioner you left out is the updated version. it is a tight fit but it does fit. some people here believe this is where the timing chain issues start from and that they should be replaced every 75,000 miles.
when I did mine I removed the sensor in the way for fear of cross threading but others have not. If your timing gear hasn't gone yet this is the best preventative measure you can have, apart from regular oil changes. I would replace it next opportunity. also be very careful with the washer that comes with it. one small crimp or warp can stop it sealing and it will shoot oil every where. dab a bit of grease on the inside of the hex head and seat the washer first then screw the tensioner in making sure it never slips off. if the washer slips off start again.

Thanks McSlug, good to know, i didnt want to take it apart and not be able to put it back together. I read the horror stories about the issues with trying to remove the sensors.

I think i will go get a replacement before i remove the old one, may as well replace it if i am going to remove it anyway.

Adding the restrictor seemed to help a bunch though, it hasnt rattled at all since i replaced it. One of these days i will tear it back apart. shouldnt take that long next time.
