I have a u12 motor without the turbo anyways when i start it up the oil light comes on for a quick 3-5 sec also the engine makes this loud clicking noise in the engine and is not the chain it seems like is coming from the other side by the nissan in print on top of the vavle cover, it comes and go alot i clueless of wtfthe sound is. Any thoughts of what might be causing it to click? also the oil is royal purple and it is on the full line.

all your dash lights should cycle on and off withing a few seconds of start up

as for the "clicking" sound.. gotta be a little more descriptive.... could be so many things.

the clicking sound sounds like its a bad vavle knocking and is only around the vavle cover and intake manifold and it gets worst when i step on gas but again it comes n go and when it comes is f***ing annoying
