Wartsila 6l20 Cyl head
Posted: Tue Jun 10, 2014 12:26 pm
I got an email seeking some help, that I am not sure I can provide, perhaps some of you may have some insight. I seem to remember having seen this issue before somewhere in discussions. Any idea...
Cant help to think perhaps you have counterfeit parts? Not sure if there are any service letters from Wartsila on this.Kindly advised recently our vessels main engine cylinder head (wartsila type
:6l20 ) have leakage of water from cyl. Head exh. valve seat.
This seat is new design with one o ring (old design was with 2 o rings).
We checked every things and so many time we changed seat and oring but leakage was not rectified Recently we received new cyl.head (6 pec) and after installation on engine after few day again leakage happen.
For your kindly information our engine work with diesel oil.
I work with this type engine so many years but they were as generator (alternator with constant speed with burn heavy oil) and we have not any problem.
I will appreciate if you can help to us and any advised to me
