Just found this doing a search.
I have a leak from the front left core plug. How likely is it that one (or more) of the other plugs are also leaking?.
Front and side one (crank) are fairly easy to get to - how difficult are the rear ones??
Having looked, the front ones look easy enough to replace .... I don't really want to spend too much on the car as its about ready for the heap - so am considering filling the external recess of the plug with either araldite or magic metal. I know its not best practice, but don't want to throw any significant money at it.
