I have the full Bukh workshop manual and assume it will be in there. However, I've had a quick look around and manual must be on the boat. I'll fetch in in next couple of days and let you know (if that isn't too long). Let me know if you need any other information. /forums/images/graemlins/ooo.gif
I've had Mistroma (with Bukh DV20) for around 23 years now and that makes it 28 years old. Still going strong so I can attest to their longevity. Had head off last year to clean valves etc. and no sign of bore wear.
my bukh was of 1977, but someone (the last owner) ferget to put in the engine the conecting rod bearing. You now the damage?
I procure spare parts (bukh of 1988 without head) and assembly two engines in one. The engine now work very good. I`m not secured only for the oil pressure.
