Black smoke after replacing turbos and injector

 It could be due to the intercooler.   Signs of defective intercooler:   black soot and oil at the underside from the leak.

How I wish I could do this: Toyota 1FZ 6 cylinder engine rebuild

TLC Diesel Engine repair 

Complete repair/rebuild of 6 cylinder Nissan Diesel Engine

 This is admireable.  With limited machinerry repair and measuring equipment.  But judging from the way the engine purrs they must have done an admireable job.

If we compare the Western repairs:

1.   Proper use of measuring tools:    torque wrench, roundness gauge, calipers

2.  Clean workplace

3.  Proper lubrication

4.  Plenty of helpers in Pakistan

5.  Westerners would always go fornew complete assemblies which undboutedly are more expensive

With limited knowhow and equipment these workersk/craftsmen have done a wonderful job
