    Yo Ho......After a long winter and a great run up from Boston , my 93 / 46 is in Nova Scotia..I am willing to bet this Post is the worlds most Northern....... I have lots to do to her , replace carpets , clean engine room , steering flat , bilges , install pilot , redo valances , wall paper etc , etc , etc...... I will have lots of questions , one right off the top of my head is with regards to the Salon deck head longitudinal ( over the windows ) valance board , I see no way to get it off for re covering. It seems secure as solid as can be , but not sure how it is secured...I am sure there is a trick to it. Trying to post pictures , not much luck , seems site will not accept large files.....

    One 6-92 runs smooth , one knocks at idle. Valves etc set , smokes alittle more when throttled , runs on par with the other at speed , seems to leave a slick in way of its exhaust.....

    As well , the temp gauges are both reading after warm up at 150 ish...The were in the high 170s with the gun at sea trial. Is the likely culprit the sensors or the gauges ?

    Culprit? Your near perfect.
    120/150 till under a good load when the motor starts making some HP and heat. Then the thermostats control the heat around 180 degrees.

    I figured it would be easy to prove you wrong, since Nova Scotia isn't that far north. The northern most point (47° 12′ 10″ N) is south of Vancouver, BC (49° 15′ 0″ N) and Paris, France (48° 51′ 24.12″ N). You're south of the entire western half of the border between the US and Canada. but I spent about 15 minutes looking and found no Posts outside of the US east coast.

    A lil black smoke could be a simple throttle delay issue if it cleans up when running. Unburned fuel in the exhaust really needs to be looked into. Over fueling or washing a lung with fuel is not good.
    I recommend getting that looked into by a real DD tech. The valve noise could be from that lung if the smoke is light.

    Chances are good you simply have a crappy injector. Get yourself as Detroit man and have it looked at.

    That's not my injector, I'm sure..

    Bob is correct to get it looked at, it could be a malfunctioning injector.

    Finding a real DD guy could be a challenge. Anybody can pull an DD injector, only a few can put one back in correctly.

    2 Stroke Detroits are history still evolving. Give them some care and they can last a long while.
    Watch for signs of needed service (smoke, extra rattle) before it (may) gets serious.

    And, we have a great Post crew on this Forum.

    ,Ralph

    You my friend would recognize a good ole crappy injector. Wrapped with bail wire and marine tex. But you are correct, it would work very well.

    Stay well,

    If the valve covers are off, go ahead and check the valves clearances and run the racks. I assume you got a timing tool with the injector and know how to check / make these adjustments?

    I did order 2....... I have also become a victim on Boat Diesel Form..... Now I am scared shitless about my 92s :p
    I do not but I will be watching my GM guy , He is used to working on the lower HP engines , I have 1.508 timing , advanced so I understand , I am not quite understanding any or this yet , I hope he knows the difference , he is an old hand , should he have one of these tools or will he know what to do without one , I am hoping to get a tool this week. As well , my new injectors came with no 0 rings. Will I need to get the proper kits or am I not getting the full picture.....

    There is nothing to be scared about. However, when it comes to work under those valve comers, there is not much in the world to compare to. That is why it's important to have a good DD tech.
