detonation. run a higher octane fuel or retard the timing by twisting the distributer anti clockwise.
Hope this helps
wheel bearings?
Knocking is usually associated with worn main and rod bearings.
Wheel bearings or shock needs replaced at that corner. Unless of course ur missing a cat o_0
"knocking" is very broad so just a wild guess here. I think the reason the knocking stops when you disconnect the number 6 injector is; you are creating a "floating piston". In other words, this piston and cylinder are no longer producing power, they are no longer under a load, and they are no longer compressing the fuel that you have prevented from being injected into the cylinder. So, if you have something wrong with that cylinder, such as a bad piston, piston pin, connecting rod, rod bearing, etc., you have relieved the pressure which will quiet the knock. Again, just a wild guess!
Depends on the sound of the knock. Could be main bearings or rod bearings.
probably broken bearings
Worn bearings from high mileage, poor maintenance, abuse,
Knocking as opposed to pinging or ticking, usually means seriously worn bearings of some sort. Time for an overhaul.
if it sounds like the knocking is coming from the bottom of the engine i would bet it was the rods or rod bearings may be worn. if the knocking is on the top ,then i would have the lifters and or the rocker arms checked.
Could be a rod knock. Your bearings slipping in the engine.
You probably need your bearings repacked
You will have to replace it. The bearings are worn out in the blower motor.
