So I pulled the motor out of my truck that had a knock and the only thing I have found out of the ordinary is that atleast two of my lifters can be compressed very easy. My question is how much force should it take to compress the lifter and would this cause my truck to have a knock. I have not pulled the heads yet but I have pulled the oil pan and all rods and wrist pins seem to be tight.
