I’m running a pair of DD 6v92TA Covington conversion engines making 435hp each. Engine year is 1979. Last fall I had my second injector problem of the season on the stbd engine, so I put in a full set of injectors that I got from Scrod. I ran her a few times in the late fall, and again this spring with good results.
This past Sun I headed out to go fishing and after 5 minutes of running (2050rpm) that engine bogged down and billowed out black smoke. After that it would only run up to about 1300rpm without smoking. I checked the turbos and they seem to be spinning smoothly. Does this sound like an injector problem to you guys or do you think I have something more serious? BTW, engine did not overheat, and oil pressure is fine.
