    how many miles on this jewel? when was the oil changed last? what kind of oil are you using? are you changing the oil or having someone else do it?

    i'm going to say either the oil is dilluted with a foreign substance which is making it thinner, thus tripping the low oil pressure lamp...or...

    there is excessive bearing clearance on either your main, rod, or cam bearings. keep in mind this is a V-8 DOHC engine, lots of clearances to discuss here.....or.....

    your oil pressure sender is faulty....or.....

    the oil level is so low that the pickup tube is sucking air and dropping the oil pressure like a brick.

    i could get the tappets regarded at for the knocking sound, which would be high priced, reckoning on what share valves your vehicle has and for the white smoke, i would not difficulty as long because it fairly is purely for roughly 30 seconds and it fairly is white.
