I'm trying to get rid of a knocking noise or at least figure out the culprit. It seems to be coming from the front of the engine. It seems to happen mostly on a warm engine and is consistent. It is audible at idle. If you rev a little it gets slightly louder go a little higher and it can't be heard. I've replaced the cam sensor, but it still makes the noise. I've taken the belt off and it still does it warm. I've re-gapped the crank sensor. I've listened all over with a long screwdriver but can't pinpoint exactly where it's coming from. It is louder at the front of the engine versus the back and seems to be louder from the top of the engine than the bottom but can be heard in both places. It also sounds louder on the passenger side near the turbo versus the driver side. The oil pressure is almost 50 on cold startup then settles to between 25 and 50 while driving but is closer to 25. It's probably around 30. At warm idle it is half-way between 0 and 25 maybe 12. I'm not sure what to do next.
