Quick question, will the upper oil pan of a 2005 g35 sedan fot directly onto my 03 coupe

 

There were a number if revisions in the newer pan, mostly just casting marks and the baffle on the top side. The only thing you will need is a new valve oil pressure regulator (ball check valve) for inside where the oil filter goes but the pan is compatible.

You'll see the valve oil pressure regulator when you compare the two pans, it looks like a little ball bearing inside the oil filter passage and the newer pan just has a hole where it needs to be put.

 

Ok but do you think i can swap it out without having to pull the motor?

 

EDIT: DO NOT GET UNDER THE MOTOR IF ITS ONLY SUPPORTED BY HYDRAULIC MEANS SUCH AS A CHERRY PICKER!

It can be done, you need a top rail mounted engine support bar, they look like this:



Support the motor, then you can remove the front cross member, pull off peripherials from the pan like the starter, filter, etc, now you have access to the upper pan.

It's got a huge gasket surface to clean so be warned it's probably not EASY to do from under the vehicle. If your vehicle is AWD it's probably going to be a total BITCH because of front differential and stuff.

 

Ok so i just ordered the oil pan this morning but i already have most of it ready, already bought the support bar, but what ive been wondering is where is a good place mount the engine, as in like where can i put the chains from the support bar to get the best support

 

There aren't factory specified lift points because it's designed to come out the bottom at the dealership but slinging from the two big bolts in the front of the timing chain works great. They're unused bolts that were originally part of the mechanical cooling fan on the '03 engines. Torque spec is 55 ft'lbs for those bolts. This thread has good pictures of what I'm talking about.

Make sure to check out the factory service manual (or at minimum a haynes/chilton) before you start.
