HELP ka24de with strange noise coming from nothing ???

[240SeXyNIS]

i have a 240sx with a ka24de-mods Intake, Exhaust-catback only strut bars lowered on lowering springs, i bought the car from a nissan tech who said he replaced the timing chain and head gasket and valve cover gasket four months ago.
A few days ago I was pulling into my driveway and it developed a sort of taping, at first it seem to be a rod knocking but listening to it, it is coming from the front upper part of the motor time chain area. And i have been trying to research this for a few days before bring it to asking like this. i was thinking of the issue being timing chain guides i know that they where replaced and are on the motor...also thinking that it may be oil pump i havent installed a gauge yet and i do have oil under the valve cover...Now for my doubts, strange thing is when i turn the steering wheel left or right the tap stops but when i let go it starts again, also if i rev the motor ( i did out of anger i know that was stupid) it stops taping , i have no check lights on no smoke and no power loss and plenty of oil...Please help out if you have any ideas
