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

Some people have had issues with the casting on the crankcase. Unfortunately, there is no way to insure that parts are not lost if the engine does have a major failure and ocme apart. We can only state that is is not a common happening for the case to catastrphically fail in the manner you mention.

Is it a common problem for the cases to crack at all? Because when the case cracks the engine usually will not idle well and sometimes quits while in flight. The B25 being a twin, I'm sensitive to losing an engine in flight. Can you recommend any precautions I should take to help insure the engines don't have an issue?

Thanks
