Wartsila’s User Group Forums 34 SG Wartsila Engine Issues with Exhaust Valve Seals Reply To: Issues with Exhaust Valve Seals


We have had many. Failures were linked to o-rings unable to support the heat. Markisches Werk analyzed the o-rings and supplied us with a high temperature replacement.

Ben Pacas  from Markisches can help you out. <> Motor services can also supply these parts. Mladen Malovic <>

During 16k overhauls we pull and replace all exhaust seats and o-rings. Since then we have had a significant reduction in seat leaks.
