thx, its the 01 making the noise. I have upped the fuel pressure with the hi pressure spring, done the intank mods, undeadended the fuel at the heads and intalled a new AE injector.
Theres no doubt in my mind something is broke. I would bet my right arm on it. I just dont know what. We just wen thru the motor, something this loud would of been hard to miss in the form of a wrist pin or something, scott"trucks unlimited" is very good too, he did not see anything. I realize he's human, so its possible its still in the motor but i think trans and have hought it all along. I had the tc rattling when i bought the truck and replaced it with an ebay tc. The rattle stopped but around that time the knock started.
I figured junk ebay tc. I bought a ford tc and replaced the flex plate too. Maybe i did not get the splines lined up all the way? The fist time i installed the tc? I never forced anything but you never know. I was always able to moce the tc a little back and forth before i tightened the bolts. But it barely went back at all. If i remove all the tc bolts now, i cant realy slide the tc back. But its not bound up.
Are the pump gears movin whil in park? I assume so, that could mean a broken part in the pump?
