hi guys! i've opened my rocker cover and replaced the cover gasket and spark plugs oil seals with new ones. what i like to know is if i have replaced the spark plug oil seals properly. i had a very hard time pushing the seals all the way to the top and applying brute force might damage the seals. what i did was simply positioned/placed the seals on their respective slots tight enough to keep them steady when i put the cover back on. is this how the seals should be replaced or shout it be push all the way up? thanks for the inputs guys!
