Of course everything has had its time at a given moment. And then replacement only helps. But sometimes there are simpler solutions.
For example, the simmer rings of cars and motorcycles of 'a certain age' may show some wear or hardening because they have exhaled their plasticizers over the years.
Think of it as a patch or a revision from a bottle, but as long as the case is technically in order, such a nuisance leak is along a crankshaft seal, an input or output shaft and a dif. good to remedy with a product that makes the simmer ring smooth again, and a little bit better.
We tested LeakLock
And that works.
