well i finally started my cam switch and got everything tore down and even got all the new valve springs installed but i spent most of the day trying to get the lifters out of the block. i went through every tool i could find at the local auto shops and in the end after about 5 hours and lots of sweat, blood and aching muscles i got all but 4 of the lifters out. all the lifters seem like theyre swollen or worn so much theres aridge that wont just let them slide out like theyre supposed to. so anyway, i cant get these last 4 to move higher than the initial top part of the lifter and am out of ideas...aside form removing the oil pan what can i do to get these lifters out?
