    Could someone identify the bracket in the above photo (at the arrows) that seems to be mounted with two bolts and a stud?
    What does it do, or is it a part of the front cover? Thanks

    Good evening


    That is 1989 - 1993 bracket used to mount the crankshaft sensor.

    Thank you that's great.
    I'm guessing it shouldn't hold any water.

    The water shows up around the crankshaft sensor bracket. I have been unable to trace it any further.

    Thus it seems the leak is somwhere in the front lower RH (passenger side) part of the engine.
    I haven't been able to find any leaking water around the pump, thermostat housing or hoses. Water level is lower than the expansion tank but still leaking. I can't start up the engine right now as a lot of parts have been removed.

    What should I look for? Where is a likely point to leak in that area?

    Good evening

    Is the coolant system components installed on the car? If so do a coolant pressure test to find leaks. You might be able to rent a kit from your local part store.

    With or without the coolant pressure tester check the following for visual coolant leak evidence.

    1. Thermostat housing including hoses.
    2. Water pump.
    3. Timing chain cover.
    4. Cylinder head to block.

    Timing cover

    Now, if there's a leak inside the timing cover (i.e. the gasket between cover and block), wouldn't there be water in the oil?

    No water in oil

    Did a pressure test. Had to put 2 Liters of water in the radiator first to top it up. Same result, looks like a leak on the outside of the timing cover below the water passage. Can't really see exactly where but don't see water appearing elsewhere.
    Found no water in oil pan when pulling the plug, so it doesn't look like it's leaking on the inside of the timing cover.
    Not sure whether there's oil in the water though. Was a bit of sludge in the expansion tank.

    Good pics, thanks.

    Seems you're not left with too many choices...take the cover off and reseal it, or try some stop leak when you get it running.

    I'd want to know more about the sludge in the tank, tho. When you get it running you can try the test that checks for combustion gas in the coolant.

    Gasket?

    Is this "gasket" available as a spare part?

    Yes I will have to see if I can move it.

    That coolant bleed 'skirt' is no longer available new, unless someone is sitting on NOS privately.

    I have a few used that aren't too bad (if I can find them), and a spare billet version just like this (just the skirt...only have used OE bolts):



    See: http://www.sccoa.com/forums/showthre...ght=billet+cap - doesn't look like they have any inventory.

    Hit me via email if you're interested.
