I do sleeve pinching...... Or at least I have the tooling to do it( i no longer offer the service )

It works awesome..... no different then a new engine...same power, same reliability......Works great if the technician doing the pinch knows what they are doing.........In some cases engines run stronger after pinching then they did when they were new......

However there is a huge margin for error when doing sleeves, and it is very difficult to get the pinch just right every single time.....Every engine responds differently, and its only thru experience that you will develop the skills to do every engine correctly...

What I found is the pinch is better to be a tad too tight then a tad too loose..... If the sleeve is not crimped ( lack of better word ), it will just relax back into the original shape.......... crimp the sleeve too tight and be prepared for a nightmare of a breakin....

In the end sleeve pinching works great, but the results are very defendant on the skills and experience of the person doing the pinch, there is a large margin for error......
