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.

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. 

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 😂

      Yeah, my moulds and seals are 32 years old now. I think I will continue to not use a pressure washer on it.

      I hear the old "I'd never use a pressure washer on my motorbike" BS in the dirtbike community too.  The only people that have had a problem from using a pressure washer on anything are the people that aren't using them properly.  If you hold the wand any more than 45 cms away from pretty much anything (radiators, wiring connectors, paint, etc) you aren't going to cause any damage.  We've had detailers wreck moulds and seals on cars at work before and the only reason why is they held the pressure washer too close and on the one spot for too long.  If you have 5% more brain power than a detailer then you know not to not do that and you'll never have a problem.

      I'm pretty much healed up post surgery so I spent another almost full day out in the shed re-arranging everything to make room for all of the shit that I've taken off the car.  I need to get everything off the floor and away from the car for when I start making a massive mess stripping off the remaining body deadener and then for the the painting process.  Almost got the shed to a point now where I feel I can actually start working on the car again (clean shed clean mind or something!).  Almost 11 years of accumulated car parts, building supplies, tools, junk, etc have taken a long time to get in some sort of order again!  Most stuff is now boxed up and in the back shed if it's not car related.  Most people would still be horrified walking into my shed but it's significantly better than it was before!   For those that saw my separate post the other day, yeah I ordered one.... This version- I convinced myself to stop being a clown, wake up to yourself and realise it will take you 5 weeks to make one by which stage you're over working on the car again...  Maybe I am getting on top of my "mental ailments" and making smarter choices.... $1450 delivered which will take my miserable half-dutch arse a few days to get over having spent that much!  If I don't have a use for it straight away after my car is off it I might even see if there is a "rental market" for them.  See if anyone wants to hire it for a period of time.  $25 a week or something like that.  I'll worry about that when my car is actually ready to come off it though as that might be a while away!! There's now no excuses now for not ending up with an underside you could eat off! Away for kids sport the next few weekends so hopefully can get the rotisserie assembled ready to go for the car to go straight on it the next available weekend.

      I always use my Karcher, but it's only a little one that I picked up from Supercheap  The only issue I ever had with a pressure washer was when I was a kid cleaning coaches, they had a hi-po industrial sized petrol jobbie that would strip paint if you got to close I saying this, we have a fairly high power washer at work with a diesel powered heater that sprays water at about 60°c, it works great for removing old wax and road grime on the underbody after some foam cannon action, albeit from a "stand off" distance of a few feet

      Sorry no - The sandtrap adventure ended the day, happened at the end of the last session. At that time I wasn't hearing any weird noises nor were the brakes shuddering anymore. It was only when watching the videos that I remembered I had these sounds early on!
