I am doing a pre buy on a 300d non turbo and found out that 1 of the injector had 135 bar written on it while the others were all 115 bar...

The engine seems to be running pretty well so I was wondering what king of damage would a 135 bar injector would do to a non turbo engine?
Is it possible that the core of a 135 bar was used to rebuild a 115?

Thanks
