TBO
Paul, My plane is a P337G 1975. Just had rebuilt engine on front. On the rear engine I had two cylinders changed and it is more than 1,000 hours over TBO. My IA doesen't seem to have a problem since it has good compression and he knows I change the oil no longer than 50 hours and we get analysis of the oil ever one hundred hour. Besides, The Seneca-V has the same engines as I have and I believe their TBO is either 1,800 or 2,000 hours where in the P337G it is only 1,400 hours. Go figure!
