i talked to them today and they are out of warranty, but i told them that the lifters were crap and that i had to tear my engine apart because of it. all they could do was offer me a discount. thats fine and dandy, but what i want to know is , are they supposed to all pump up hard as a rock ? i just tore apart a beautifully painted engine and i dont want to do it again especially if i am doing something wrong. im not a novice by any means, but this is something that i have NEVER had an issue with, so i guess ive just been lucky
