Hey guys. So im having an issue with code P0021 on my 2010 FX35. First i changed the vvt solenoid but it was unbranded and cel didnt go away so I ordered the hitachi ones but havent installed yet. I checked my oil and saw it was low and had an oil change done and changed the filter as well and the code still comes on. Do you think the issue is the unbranded vvt solenoid or maybe that theres some sludge in the engine? Or something else? Also which brand of the vvt solenoid would you reccomend?
