TM 10-3930-671-24 Table 4-2.  DS/GS Troubleshooting Procedures - CONT. MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION ENGINE (CONT.) 6. WHITE EXHAUST SMOKE - CONT. Step 4. Remove fuel injector from cylinder with lowest compression rating, squirt oil into cylinder, install fuel injector, then check compression at that cylinder (Appendix F, Engine Compression Pressure Check, Section 4.6). If compression reading rises for that cylinder, faulty compression rings are indicated.  Overhaul engine (Appendix F, Continentel Diesel Engine, Section 4.14, Section 8). If compression reading does not rise for that cylinder, sticking or burned valve is indicated. Remove and repair cylinder head assembly (Appendix F, Continentel Diesel Engine, Section 4.14, Section 8). 7. TRUCK SLOW TO ACCELERATE. Step 1. Check for faulty fuel injector(s) (Appendix F, Continentel Diesel Engine, Section 4.14, Section 5). If fuel injector(s) is faulty, replace injector(s) (Appendix F, Continentel Diesel Engine, Section 4.14, Section 5). If fuel injector(s) is OK, go to step 2. Step 2. Check that fuel injection pump timing is properly set (Appendix F, Continentel Diesel Engine, Section 4.14, Section 5 ). If fuel injection pump timing is not set properly, set timing (Appendix F, Continentel Diesel Engine, Section 4.14, Section 5). If fuel injection pump timing is set properly, injection pump is faulty.  Replace injection pump (Appendix F, Continentel Diesel Engine, Section 4.14, Section 5). 8. ENGINE KNOCKING. Step 1. Check for faulty fuel injector(s) (Appendix F, Diesel Fuel Injection System, Section 5.3). If fuel injector(s) is faulty, replace injector(s) (Appendix F, Diesel Fuel Injection System, Section 5.3). If fuel injector(s) is OK, go to step 2. 4-5
