Re: MAK ENGINGE EXHAUST VALVE INSERTS CRACKING

eugyno--

 

One possible explanation could be the fresh water quality.  We have seen similar problems -- what we call "Stress Cracking Corrosion" -- which is caused because of an incorrect mixture of fresh water additives in the HT-water system.

 

Could this explain it?
