:lol:

It beggars belief doesn't it?
 
Facepalm actually.

I'm also inquisative as to whether I can build up a back pressure by putting my hand over and occluding a running exhaust tail pipe. Just because I'm inquisitive, doesn't mean I will do it.

i just don't understand the problem with taking your filler cap off whilst running. how else do you check for blow by?

people are saying there's more chance for crap to get in your engine and fcuk it up, but running or not running there is still a hole for crap to get into.

i lost my filler cap when i visited relatives up north and drove 100+ miles with a t-shirt tightly folded and wedged in the hole.

as the old saying goes "if a man feels the need to remove his filler cap whilst the engine is running, for no reason what so ever, just to see what's inside, then leave him be"
 
what is blow by?
i am baffled as to why you would need to remove the filler cap when the engine is running?

Blow by is where exhaust gas's leak past the piston rings or past valve stems creating pressure in the rocker cover or steaming out when oil filler cap is removed.
Other than that there is no reason to remove oil filler cap unless filling with oil. But there is no law saying you cant. Its your motor you can do what you want with it.
 
Aswell as checking for blow by, Why don't you check to see if your cams are moving, by putting your index finger in there.....
