After having a lifter tick for a good while, it's gotten alot worse, so I guess I've got to address the problem. I put this motor together six years ago and I can't remember if I'll have to pull the heads or not? What say you guys? 302 with brand new ford lifters when I put them in. I thought I soaked them and pumped enough back then and the one that ticks only started acting up just over a year ago ( I don't drive it a whole lot ) p s, I tried a bottle of the Lucas additive with the last oil change, but it did'nt help.
