Yeah I removed the valve covers and it didn't look like any where, but just for extra measures I tightened down each and every rocker arm again, making sure each cylinder was at TDC, and I noticed something, the manual said to torque them down to 18-20 and when I did I noticed that some of the push rods wouldn't move when torqued down that far, but most others would, the cylinders with the highest compression had no trouble torquing and still being able to turn, but the 7 and 8 cylinder and 3 wouldn't budge even the slightest when torqued down, so I backed them off until they were able to move, I ran the car for a little bit and it did a hell of allot better, but I removed the valve cover again and noticed that the nuts had started to come off, meaning that they weren't tight enough, however they were the tightest they could be and still have the push rods turn, so it got me thinking that maybe the valves are the problem, but its not the valves causing the problem, what if it is the lifters and they just got stuck, so I cranked the engine with the covers off and well what do you know 3 valves were staying down
