I own four Fuji 32 engines two in airplanes and 2 in the box waiting to be mounted in a new Ziroli B-25 i'm building. In my club we've had a lot of problems with the crankcase cracking on the engines just below and along the head gasket. I've already had one of my engines replaced because of this crack and I know of 5 other engines that belong to 3 other club members that have also had their engines replaced. I also know of two airplanes that were lost because of this. The head fell off while the engine was in flight. Yes, I saw it with my own eyes. Bottom line is their a problem with this engine or what precaution can I take to avoid this issue with my B25!

Thanks
Steve
