My engineer seems to think it is the lamiflex. They are bleeding alot of ruber. As you mentioned maybe a bad batch. Damper's seem ok. We are going to try some other Lamiflex's to see if this helps. If it is a bad batch, do you think the factory would come to the party, and do a pro-rata as the machine has not flowen for close to one year, and the lamiflex have still one year to run? So they have been in this condition for two years out of there five year life.
