If there is suction will be also "exhaustion"... right ? well, the plug/paper is not being spitted out either on exhaust stroke. Just blows out when the comnpression stroke comes in. God... I have made it many times!!! Its like the ohms law! the flow will go throught the less resistant path! having any kind of plug, air will leave and get in just throught the valves. The minimal amount of suction or exhaustin over the plug won't affect it having the valves in working order. With a Charger born in Chrysler assembly plant in Valencia, Venezuela

The stop is at such an extreme angle, almost horizontal to the top of the piston, that the force of the piston can easily deflect the stop if the stop isn't REAL stiff and rigid and too much force is applied. Insert joke here.

The minimal amount of suction or exhaustin over the plug won't affect it having the valves in working order. It's the power stroke that will cause suction during down stroke with both valves closed. If you don't believe it, go out in the garage, pull a plug, put your finger on the hole and crank it over.

I have made it many times! And the paper ball has being bever sucked in! It is of course a bit bigger than the hole and even being able to, somehow, get threated into the hole This is allmost becoming like the eternal ammeter/alt upgrade discussion...

I have no idea the physical details of either. Frankly finding TDC is so easy I would have never thought of it as a trick. But you are the one that implied that it was impossible to have suction because the intake valve was open. I think you said it twice. I simply pointed out that you were incorrect.

Mount a “slide whistle” to spark plug threads, pipe a steady air supply to it from a battery powered mattress inflator, then use a smartphone microphone along with an APP to measure the frequency of the low frequency sound at bottom dead center, and the higher frequency sound at top dead center.

Originally Posted By BSB67 But you are the one that implied that it was impossible to have suction because the intake valve was open. I think you said it twice. I simply pointed out that you were incorrect. yes, correct, but on this case after the plug was already spitted out . I meant because the plug won't be sucked on that moment because there is not a plug on that moment . and still, I have made it many times installing a plug there without consider that and never have had anykind of plug made being sucked in With a Charger born in Chrysler assembly plant in Valencia, Venezuela

Maybe some time met the power stroke and it has NEVER happened to me With a Charger born in Chrysler assembly plant in Valencia, Venezuela
