    (87 3.2 Cab - driver's side rear frame) So...trying to figure out the best way to replace the oil cooler thermoswitch when I noticed this in the frame - assume it can be welded after "A-frames" removed...looks like it's an old injury...passenger side fine - would be interested if anyone else has seen this - Thanks,

    Gotta be an old injury. I can't imagine something like this happening as a result of age and fatigue. Unless, of course, your car has been driven over 300K miles on mostly unpaved roads. ;)

    I am sure that can be welded. It does look to me like the old weld failed.

    I would get that weld fracture sorted out ASAP. Also check the other rearside. Whilst you are at it have a check of the front lower wishbones around the mounting points.

    I had this happen. And it was only found when I had my engine out major many years ago. It was welded and never again an issue. Interestingly, I didn't know it was broken as my car was driving fine before the major service.

    My 3.2 coupe is undergoing an engine out major right now. And my mechanic spotted the exact same kind of crack in nearly the exact same place! Also appears to be an old repair/weld that failed. Must be some inherent kind of weakness in the frame at that location. I'm hoping he can re-weld it good as new.

    When re-welding, add a triangle gusset to the exposed sides where there is room.

    Also make sure the surrounding area is properly cleaned and prepared.

    Home Remedy:

    Clean well and build up a lot of JB Weld layers strongly packed in place very thick. The car works fine. Fix it in place. A pro fix would cost all sorts of bucks, and it would be an iffy fix anyway. And the cost would almost certainly more then the JB Weld would reduce the value. Hell, I totally boxed in my rear suspension menbers on Mark VII with short water pipes and packed with JB Weld. Never failed.

    But thats just me. I love being a gadfly......

    PS: After the first few layers add in some small angle irons. ;)

    I do not quarantee results of course.

    Ha ha ha, Classic!! That's funny. Seriously though you know you've got to be careful here joking like this or else some nutter will actually take you seriously and try gluing their cracked suspension arms together again with JB weld and kill themselves in the process. ;-)

    Although the fix does not look easy to me given the accessibility, the JB Weld thing was only half in jest. And I specifically said "I do not quarantee the results". Frankly, if EYE had that situation a JB Weld build would be exactly what I would try first.

    The issue was oil cooler replacement and then: What the heck is this! Apparently a long standing damage! I would simply stabilize this long standing damage with steel reinforce epoxy, plus angle irons, and see if a crack reapeared just driving 1) down the driveway 2) normal driving 3) some low speed hard turns.

    The JB Weld stuff is easily knocked off. And actual welds of this sort are way way tricky and might fail spectacularly themselves. Its just me. My advice is to never take my advice. Just know what my advice is. And do what you want to do!

    And yes. I used such epoxy to box in my Mark VII rear suspension arms. None of them ever failed.

    Hi Tom it is interesting to see a failiure here, I will be checking both of ours for any signs of fatigue etc.
    Fixing it however will be a doddle for a good welding chap but I think I would add a simple small web fillet triangle as a strengthener when you fix it.
    Regards Bell.
