no there has not been any problems noted about the head button and the block leaking nor has the front bearing leaking on the JPX engine. But if you have a Nova Rossi type plug in your engine you should chage it out the threading on those plugs do not match well into the Picco head button and causes leaks or bubble out fuel and when you tighen it to prvent it from leaking and you got back to a Picco plug the the head button treads are opened up to the point where it leaks even more and then you have to replace the button.
