Bank 1 02 was put in on Friday. Bank 2 is older but going through the numbers just like bank 1 is. (4) My springs are rated 155# on the seat. I did set the pre load at 3/4 turn this time with the engine running when I put these AFR's on. To much? BLM's get better when the motor is revved slightly. Could this be it? Maybe just not enough oil pressure at idle for the lifters to work correctly? Once revved up some the oil pressure increases and that is why the BLMs improve dramatically. I should be so lucky...........Have I been chasing a Ghost? |
