    I have 370B’s and just noticed an oil looking leak coming from my port turbo.   Can someone tell me the cause and repair.  Thanks.  Rich

    Tony,  the boat (31 Blackfin) was repowered in 2009 by your friend Bill D.   I purchased the boat from Bill in 2014.   I will check my computer for some photos tomorrow.     They have about 1100 hours on them.

    Richard,

     

    Let’s get back several feet and get some good pics of the engine installation so I can “SEE” everything.. Put my eyes and Rob’s too, in the engine room.. 

     

    Exactly when were the engines installed and how many total hours..

    Rob thanks for the quick response.   My motors came from Tony and are equipped with the Enviro system.   Is the leaking possibly from a dirty air intake filter? Or a dirty breather filter.   Can the breather be cleaned or do I just replace it.    Also what’s the best way to clean the turbo.  

    Also, I just pulled my aftercoolers off for cleaning and the air side was clean.
