He also mentioned that this new seal has to be put on dry to the crank and pushed by using the tool that he have...

Have you seen any car with RMS issue with this latest seal ??

We have installed many of them over the past several years, and never had one leak to date. That said, we have seen ones were the new seal was not properly installed (how deeply they are set into the case is critical, as is making sure they are installed straight) leak because of how they were installed. Replacing the miss-installed seal with a properly set new one corrected the issue in these situations. There have also been reports of engine cases that the crankshaft openings were not correctly machined, or had bad crank carriers, where no seal will work (the engine has to be replaced).
