Well, figured I'd revive this thread yet again. Just got the new head on. I have the revised lifters in there. Still getting my phantom knock. Again it's only when I'm below like 3500 RPM. I am set at like 16-17psi because I can't get it any lower. I have a half & half mix of 91 & 110 or whatever it is that they sell at the Mobile1 station. I have new lifters, tried the MCCC cleaner, replaced the knock sensor, base timing is set to 5, brand new head from FFWD, fixed about 95% of my exhaust leaks, I've tried richening it up with my SAFC, Rotella-T oil in it, nothing seems to be working. I can still here a little ticking when the engine is idling. I have no idea what it is, but I can hear it slightly. I am going to try retorquing the Knock Sensor again. What size socket does that take? And I think someone in here said it should be torqued to like 6? Is that right? Do I need to use teflon or anything on the threads?
