I had to change the main bearings in my puma 1.7 vct, and ford state that its a paste (silicon) gasket. The mechanic at ford said that the best one on the market was the one from Nissan dealers. I have used this many times, and it has been absolutely brilliant, never an issue. Quick warning, don't get any on your clothes, because it doesn't come out, took my top off after using it, chucked it into washing basket on wife's new jeans, to say that she was a little grumpy when she had to throw them out was a little left of the truth.
