Pull AWD Oil Pan (GTS4 / GTR) while engine is in Car?

[corbic]

Is it possible to pull the oil pan with the engine in the car? I've not found any videos of photos of someone doing it.

I haven’t personally done it but yes you could.  Would I?  No.  It would be a very fiddly job and arguably not worth the effort.  Have you ever picked up a GTR sump and diff on its own?  They’re incredibly heavy and incredibly unbalanced making them really hard to manhandle in the best of conditions!  Trying to lift one up through the frame rails and then try to get a few bolts started would be a nightmare!  I would pull the whole engine (downwards) before I tried it.

If you do decide to do it you will need to support the engine from the top and then completely remove the k-frame off the bottom of the vehicle.  
 

Let us know how you go!

Yep, there's a reason there is no videos showing it. It might not be impossible but taking the engine out is far easier.

You need the subframe off which means brakes etc off too, gearbox off (because the rear main seal to sump bolts are in the bellhousing), driveshaft out etc. Plus when you reseal it you need a good bead of silicone lined up correctly for bolting after dodging the oil pickup

Plus, depending on why you are doing it, if you find a problem inside the engine it still has to come out to be fixed. If you are just fitting an extended sump or changing the oil pump relief spring you might want to consider a better oil pump at the same time depending on why you are changing it which is also engine out.

You'll be silly to, much easier to remove the motor/gearbox all as one unit.

And pulling the engine means either separating it from the transmission, engine out the top with hood off, or dropping everything out the bottom by removing the front suspension.

Possible yes, realistic no.

Forget this idea - It's a box out and engine out job as everyone has recommended to you.

Seen it done once by first time GTR mechanics and it was hilarious 😂

Oil pan in an RB26 is not a trivial job like a lower oil pan on most cars, it is engine-out as everyone else has said. Do not even think about attempting it any other way.
