    Hey guys,

    So today I finally got time to work on the M35a2. Removed all the injector nozzle and cleaned them. I also did a injector pop test on all of them. They all open at the pressure the (tm 9-2815-210-35) recommends and they did not drip or leak when high pressure was left on them. Then I checked the cylinder compression on all the cylinder with my custom Compression Tester I made. All cylinder where good on psi and held pressure. I am now stumped what to do. Tomorrow I was thinking to maybe check injector pump fuel adjustment screw, The cover is on it but there is no safety wire on the bolts. May be it loosen it self or it was not properly tighten. Any ideas. Thanks -Chris

    Just my two cents, but my Dodge was blowing white smoke bad about 2 years ago and an old diesel mechanic told me to pour in a gallon of cheap ATF. I havenít had a problem since and the Cummins runs like a champ. Now I run a quart every 3rd or 4th tank.

    You know that doing to many fixes at the same time will fix the problem but then You will never be able to post what the culprit was.

    Was there a reason you tried to measure the injector return line. Looks about right.

    Hey guys,

    So today I checked the injector pump fuel adjustment screw, and it look good. I also checked the Throttle linkage & the IP Timing they where good too. Finally I check the air breather filter & it was clean swapped it with a new one too. Now I am out of ideas what to check truck still not running right. Also is there away to check the Injection Pump Hydraulic Head (High Fuel Pressure Side) with the IP pump on the truck?

    If the truck has idled a lot, it might stuck rings. Put as much weight in the bed as possible and drive it hard for an hour or two. Get it hot and drive it hard, the multi likes to work.

    I was thinking of that. But if it was stuck ring when I did the cylinder compression check it would have showed up. I would think
