00' Bonnie SE - Is It Usually Only The Valve Cover Or There are More factors??
 

So I've been having this Oil Leak from My Front Valve Cover (Or So I Think), It Soaks the Whole Front Bank Cyl Head & Drips down to the Exhaust Pipes, makes it smoke when its running, The rear seems to be in good shape.
A Lot of people have suggested Changing The Valve cover gaskets and that should solve the Problem, I Finally got a Set of DNJ Gasket Set (DNJ-I Hope Its a Good Quality Brand). I'm about to do the Valve Cover along side Other problems I'm having with the Car (Which I Will Be Posting In Different Threads). So, I'm appealing to those of You who have done this Job before Or the Master Of these cars, that can give Me advise on how to go about It, I know its a fairly Straight Forward Job, But, I could always use extra Tips/Caution(s).
Also, While doing the Valve Cover, is there any other repair/maintenance routine that I should do while I'm at it?
I've already got Gasket makers/Sealers to go on the ends and stuff. I tried to search on here to see what I can find, but nothing helpful really came up.

Youtube Link to a Little video that I made, hope it makes sense.
