you will have better luck with a new engine, the pincher could work but if the engine has had dirt or somthing in it, it wont help, the 2.5 is a .15 the 3.3 is a .18
but to awnser you question, pinching is a common practice, the pincher only works if there are no scratches on the sleve and piston, then you may be able to extend the life of the engine a little.
