ive tried this with a bee r , and the plugs were still golden brown after the 5minutes in redline. yes its loud , yes it might possibly ware the rings down over time but running the motor lean will cause far more damage than the bee r.
now ive wasted $20 on spark plugs to prove a point.
Youve completly missed the point and have proved nothing, you wasted like 20 double cheeseburgers .
Like you turning your engine over by hand except it has spark, does that count as the engine running lean? NO. Pull the plug out sure it will be white.
This is because spark is still being applied and its not burning anything. The POINT is that the engine isnt firing, no explosion going on in the combustion chamber. So therefore if there is no explosion going on this makes no stress on anything if there is no fuel so there is no lean condition(Once again because it isnt firing). If there is fuel there your washing the rings.
So because the spark plugs are white does not show that there is combustion/firing going on and that cylinder is running lean, beacause it isnt RUNNING in the first place. Its just going through its stroke.
So in the end applying spark to a plug with nothing to burn, I doubt is going to ruin the plug, or washing your rings, you choose.
