Review on πŸ’‘ Lisle 21100 Large Valve Lapper: Effortless Precision for Valve Grinding by Jeff Long

Revainrating 4 out of 5

Good reliable basic tool

I have had manual valve lapping since I rebuilt my first engine in 1963. Remember that time is the enemy of this rubber; that means they don't last more than 3 or 4 years; But for the price, you can afford to throw them out and buy new ones every time you need them.

Pros
  • Good item
Cons
  • Sparse instructions
