Gen 5 Rocker/cam Cover Gasket Replacement

[El Saundo]

Hi guys. I've had a very slow and unsightly oil leak from the rocker cover gasket for a while now. The engine bay's also looking a bit tired and in need of a good clean up with rusty Battery and fuse box brackets, which I plan on treating and re-spraying fairly soon. It's time to bring back the shine! I was wondering what I'd need to remove to get the rocker cover off and whether I'll need any other replacment parts other than the rocker cover gaskest for the entire process. I haven't had a proper look yet but I get the impression I'm gonna have to remove the throttle body and inlet manifold aswell, I pressume there are gaskets involved with these parts that might also need replacing? Has anybody done this job before and can advise on any potential pit falls? Or could just re-tightening the bolts sort it out? The car is a '91 facelift JDM GT-R with the 3S-GE lump.

Cheers
