Takes me longer than a minute to put it on. :lol:

I have had it take me a half hour to install a 521 L block oil pan, but I did it without removing any cross members except for dropping the steering assembly by un-bolting the idler arm, I didn't lift the engine either, I did it by dropping the pan as far as possible, then removing the oil pick up tube, then I could get the pan out, I had to reverse the procedure to install it, get the oil pan in there, and then without touching the gasket on the oil pan I had to re-install the oil pick up tube, then install the oil pan on the block.

I did this because I installed a L20b oil pan(620) into my 521 by accident and the steering assembly would not bolt back up into position as the oil pan was in the way.

An old-timer once told me to start with a can of "Arid" spray-on deodorant, and spray it from top to bottom on the engine.  Baby powder works too, but you have to make a bigger mess.  The powder will "wet" with oil, so you can see your leaks.  Clean the engine and repair leaks from the top down - you'll generally have less to repair if you follow these simple steps. 

All leaks will eventually look like they start from the oil pan or rear main seal.

A gasket is going to fit and seal. Goo is ok if you know what you're doing, and the engine is out on a stand, but too little doesn't work and too much can squeeze out into the pan and float around. And iot's messy. Nissan didn't use it when they put your engine together. I cannot see one advantage to it unless Sunday and the store is closed..
