Thanks in advance for the help. After my engine was rebuilt I sent my injectors to be rebuilt by Rosewood diesel. The engine ran a little rough at idle and smoked on acceleration. I have an Autoenginiuty (AE) scanner. At warm idle, ICP is just under 500 PSI. Of course, it bounces around between 450-550. ICP percent is about 9 and the volts are close to 1, again at warm idle. I didn't have any other codes. Checking the oil pressure at the HPOP reservoir, it was 55PSI at start up, 48 PSI when oil was 126F, and 18PSI when oil was 200F. The idle does seem to become rougher when the oil temperature reaches 200F. Fuel pressure at fuel filter housing is 60 to 65 PSI when warm even under hard acceleration. Compression is 350 to 400 PSI. Buzz test and cylinder contribution test passed. I took it to a local shop after I couldn't figure it out. They sent injectors to their distributer and they said the injectors were over fueling at idle and under load. I sent the injectors back to Rosewood and they went back through them again. They said they were out of spec by a small amount and they weren't sure how that could have happened. They double checked everything and sent them back to me. I installed them again and could not tell much difference. I ran it a few hundred miles, since it ran very well otherwise, to see if anything changed. I just checked everything again and now cylinder number 2, failed the contribution test, and the sound at idle is a bit louder. I have yet to open the valve cover. My plan is to contact Rosewood again today. Any suggestions would be appreciated.
