    Gentlemen,

    We have a 2009 MAN diesel engine, model no. D2842LE410 with the serial no. 70122258022224 which is suffering from a leaking sea water pressure regulator, part no. 50.06401.6000. I have attached a supporting image.
    I was wondering if a repair kit exists for the pressure regulator mentioned above or does the complete unit need to be replaced once it starts leaking.
    The above engine operates in Egypt, in the Red Sea which is a very warm environment with very warm sea water. From your view, do you believe it is possible to completely remove the sea water pressure regulator and fit an elbow instead which is also a setup existing in many other MAN diesel engines. If my suggestion is possible, is there an original part available from MAN in order to carry out the suggested modification to the engine?

    Thanks....

    I don't know the answer. I'd recommend emailing Pete Angel at Marine Diesel Specialists in Fort Lauderdale, FL. He is excellent and has given me lots of advice over the years, is and has been a MAN dealer for decades.

    Good morning Oz,

    Yes, I finally contacted MAN Europe and an original parts kit did exist which can be fitted instead of the sea water pressure regulator and it converts the system to a standard and permanently open system without any restrictions in order to ensure full flow at all times and more efficient cooling in warm climates. I can send you the part numbers if you need to order it. It is extremely useful. We have fitted it and the engines now run much better in summer. Best regards, Tarek

    Screwing in these valves to remain open permanently, you will get heavy smoke at start-up, until they warm up.
    Another insider hack is to notch out part of the bronze valve to allow some water flow while they remain in the original position. It should be enough to eliminate the smoke.
