| Several year ago I managed to buy a product called Kraus Bond ( or could be Kraussbond ) that you just dropped down the spark plug hole and it helped seal worn piston rings. I have searched the web and can find no reference to it. Does anybody know if its still available, or something similar, and if so where to get it from .? |
