My m998 with a 6.2 has a few trickey problems---Bough t it dead---no pcb--all glow plugs bad--had antifreeze and oil in it when i got it--installed new pcb --got it to start----when it runs it sometimes backfires through the intake for 20 seconds and then runs with a miss for 1 or 2 minuets then misses through the intake again----do the intake valves sometimes get hung up?---also have a leaking injector causing smoke and sometimes hydraulic lock of the engine-----could these problems be related if the same cylinder--thanks---
