Upper Oil Pan Replacement - Different Generations?
I've had a crack in my current upper oil pan (2003 G35 Coupe) for a few years now that has progressively gotten worse.
Time for replacement.
I ordered a new Upper Oil Pan from InifintiPartsUSA and it arrived today.
However, when comparing a 2004 Pan (my buddy gave me one as a backup after his motor build) to this new one, I noticed differences that I hope someone experienced in this can ease my mind.
RRmedic and str8dum1, Im looking in your direction

On to the pictures.
Oil passage blocked on old pan
Not blocked on new pan.
Bolt blocking hole in old pan.
Nothing in new pan (move the bolt?)
Casting differences on right side of pan.
Old, has something here.
New, deleted it.
New, nothing.
Old, something...
New seems to have a splash pan or something.
Old, doesnt have one, nor does it have the mounting points for it.
Casting Mark New, AL5 #7
Casting Mark Old, AL5 #3
So are these just different generations, and will it work the same?
When I ordered the part, I entered my VIN to make sure the part was correct, and this is what showed up.
I assume I have to move that 1 bolt, but what about the other passage thats blocked?

my dealer charged like 18$ for it. I remember i was super pissed and was on the verge of cussing them out.

THANK YOU
I called my dealership and was trying to describe it to the guy, he had 2 parts listed, one was 6 bucks, then other was 16 or something.
Must have been the more expensive one.
Does it just press in, can I tap it in with a brass drift or something?

k So I called the dealership back.
$14.43 PER SEAL-O RING. lol.
$16.59 for the check valve (or as Nissan likes to call it VALVE-OIL PRESSURE REGULATOR)
$2.80 for the GASKET-WATER TEMP SENSOR
The actual "bolt" or plug that I have to move over is no longer made according to them lol.

Yeah. I would simply spray some WD-40 on the old bolt/plug and transfer that over...but you already know. About the check valve. That's new to me. I replaced my upper oil pan many moons ago too and don't recall it coming without it. I'm sure it's there or I would have noticed it, just as you did.
I hope you can get that check valve installed and working properly.
Good Luck.

So I went to the dealer, picked up my parts, and brought my pan with me to see if they would be kind enough to press it in.
The crusty old man gave me a buncha attitude saying they would need a work order, I said it would be a 2 minute job...either way as usual I just took it upon myself which seems to be the best solution lately.
I froze the valve over night, then tapped it in with a brass drift and a hammer.
Removed the bolt from the other pan, cleaned it up, hit it with some thread sealant and installed it in the new pan.
So there you go, hopefully this thread is helpfull for someone down the line.
