    ouch, that's one nasty break! a quick google search shows one on ebay for $149. no idea what they go for but i would probably jump on that. first maybe i'd call steve at (formerly) tousley to see if he can locate one -

    if this part turns out to really be unobtainable at any price, there are probably some other solutions you can rig up to get the car running, but i would only look at that as a last resort esp with a rare bone stock car like yours.

    best of luck with it :beer:

    Thanks. That auction ended by the time I looked at it. I have a couple leads so hopefully I can track one down. Need to keep it as stock as possible, for sure. Will be making a few phone calls tomorrow on it.

    Yes, my problem was exactly the same as yours, leaked at the same place. I ordered the complete Speed Concepts kit and everything is fine now.

    Anyone ever figure out the part numbers for the viton seals? I already have the socket for the shaft and I think I only need the seals for cooler because I'm only leaking coolant and it doesn't look like oil and coolant is mixing. Does this sound right?

    I have a complete set of seals that I bought from Speed Concepts and would sell. I was able to find a complete oil cooler that already had been re-sealed and is working great. I have every seal except the oil flange gasket but if you're just rebuilding the cooler then you may not even be pulling the flange off the block. Mine broke, I had to. Shoot me a PM if you're interested. I will try to keep tabs on messages. You can e-mail me also at douglaspjennings at gmail dot com.

    I thought I would post some photos since the photos the original poster put up seem to be gone.

    My process was as follows:
    * drain oil
    * drain coolant from radiator petcock (only about a third of it comes out this way)
    * remove front driver side tire and splash guard
    * remove coolant hose from oil cooler (another third of the coolant will come out, so be ready)
    * remove oil filter
    * with a 12mm hex head, remove center bolt/core from oil cooler (mine came off a bit too easy I think ... supposed to be torqued around 45 lbs-ft I think)
    * pull and rock the oil cooler back and forth to dislodge and remove it (there are two large o-rings holding it on that align in a vertical position)
    * take out the (4) 10mm bolts that hold the oil adapter on and remove it
    * pry the center core of the oil cooler out with a screwdriver; work your way around it; you are pushing the tip of the screwdriver down to make the core release from the o-rings & sealant holding it in out the bottom
    * there are (6) o-rings that will need to be replaced; I found them on eBay for $35 (see pic)
    * after cleaning, use some RTV sealant to hold the (2) "size C" o-rings in place during assembly; I applied it sparingly under the o-rings and let it dry before lubing all of them with a bit of oil for assembly

    I seemed to have oil that was coming out the weep hole. It was hardening next to the weep hole. I had to use the wire wheel on my bench grinder to clean it off. I also re-drilled out the weep hole to ensure there was no blockage.

    UPDATE: I was told by Fel-Pro that the Fel-Pro 70801 oil filter gasket was an upgrade to the Fel-Pro 70415. I had used this newer style on a couple different 4.6L blocks in an F-250 and an Expedition with good luck. Well, it turns out that this new style is shaped a bit different. If you look closely at the pics below of the "new" style, you'll see that the upper portion of the coolant passage is a bit larger on top than the "old" style. On this aluminum block 4.6L the passage is a bit smaller than on the steel blocks I've had before, so this new style caused leakage. I ended up putting some gasket sealant on either side of my old Fel-Pro 70415 and reusing that.

    Much appreciations for the detailed pics. This little job could be lurking around the corner for any cobra owner. Luckily I got away with tightening the shaft.
