well i dident leak test my bike and 3 weeks later after a rebuild with a new wise co this happend
heres a link to build one http://www.blasterforum.com/do-yourself-20/diy-leak-tester-51102/
Just another reason I prefer using cast pistons such as "Stock","Namura","Pro X","Vertex","WSM",etc,etc....
For those that prefer "Wiseco",thats cool,just make sure you warm it up before blasting your blaster. I've NEVER had the issues seen in the above photos while using a cast piston,and I've never had one fail,because I inspect things.
Just for the record,...Wiseco "forged pistons can fail too...
