Re: Guide for solving oil leaks on British motorcycles.
My WDG3L chaincase does have oil and amazingly does not leak! Many years ago, I fitted the "T" section rubber gasket mod in place of the original round one and backed that up by careful attention to the spacer for the through-bolt, which I understand is where most of the problem originates for the AMC tin chaincase........the spacer gets left out, or is the wrong one, and the case distorts.
