The reason forenginefailureis 99%usuallyhandlingerrors. In this case,I brokethe threadedvalve housing wall of the valve house on the original cylinder because Ipullednutawry by misstake when i wanted to tighten it up harder to eleminate a minor air leak. And the reason for reduce leak was to beat Ronnies DL exceptional low idle run.
Because of this misstake and broke of the origin cylinder I replaced it with a used cylinder what laterexploded by a hiddencrack thatI missed when i bought it.
After the cylinder explosion i repaird the first original cylinder what still runs. I did cut out a piece of the exploded cylinder and velded it to the origin one as shown in the picture.
