Our engines are new and we’re new to the Wartsila world. We are suffering some of the same issues. We are leaking exhaust gases into the cooling water as well. We detect carbon monoxide in the expansion tank. Wartsila has been unable to identify exactly which head is leaking, because apparently the leak is minor. They also borescope, but they won’t tell us what they are borescoping and what they are looking for. Jeremy you mentioned borescoping the head/cylinder. Can you elaborate on what you are looking for when you borescope?
