Jsyk, it made a chuffing sound with the glow plugs out, but it did not make the least bit of a knocking noise. A ticking sound maybe, but little or nothing more than that
Is it a constant stream of black smoke? Or a puff puff?
Finally got to watch the video.
Can you feel it blowing back out the intake?
In the video it really sounds like an exhaust leak on 1 cylinder. I know that doesn't explain the missing or black smoke.
