Unless you have a link to people talking about removing it with the SC on I'm not going to waste my time. I had a similar situation with a previous car that I wasted a couple hours trying to avoid removing other things first which would have been a lot faster in the end.
I've read a couple times about people blocking off the symposer but I have no idea what it even is?

It is easily disabled by plugging up the top pipe, see here: https://www.jaguarforums.com/forum/f...5/#post1553181
I did exactly that on my F-Type, took all of five minutes and it sounds much better.

I agree with you that the SC needs to come off. BUT I was posting that you HAD to remove the SC to swap out the rear water manifold but had at least 2 people post back that they had in fact changed the rear water manifold and one guy even changed the SC oil with the SC still mounted! These were V-6 cars too. So it is possible!
That's why I said several talented members as I also won't try it without removing the SC!

It seems like most of your questions have been very well covered, but I'll add that even when you pull the radiator drain plug, expect a lot of coolant to still remain in the hoses, etc. Even after opening the radiator drain plug AND removing the coolant plug on the engine block (which also dumped a ton of coolant), every time I removed another hose, it was cleanup on Aisle 3.

So I just replaced the water pump and belts, but the plastic connector that goes into the front of the waterpump looked damage and sure enough it was leaking after. I just ordered the brass replacement upgrade, hopefully that should do it. I'm suspecting that was why it was leaking before. I did break one hose clip so now I'm trying to find those. I also saw a few other damaged things that I'll probably work on next. Whoever owned this car before me took it to the wrong mechanic.

I've been so focused on coolant leaks, door locking issues, and timing cover oil leak that I've not spent much time monitoring consumption. I have only driven it about 3k miles and I changed the oil soon after I got it. I did look the other day and it seemed lower than I expected because I believe when I last checked, it was at the end (to the right lol) of the metered bar graph. I wish these had a dipstick so I could more easily check it but I know of the trick of opening the hood. Is the PCV controlled by that round device on the valve cover on passenger side? Is there something I need to check PCV related which would contribute to that? I have come across posts talking about a catch can on these but never paid attention to them yet. I don't like the idea of losing much oil so where is it coming from? All that is blow-by? I had a 13 with 120k and it never used any oil between changes and I would go over 3k miles and sometimes not until when the computer said to change oil. My gaskets were supposed to be here today but got delayed until tomorrow. Any help is appreciated and I was hoping to put this back together tomorrow.
this is front of supercharger after sitting from yesterday. A lot of oil there it seems. Looking at pcv pipes I don't see them wet at the openings.

Is it the PCV membrane and should I get a replacement cap and diaphram? Oil seems more prevalent in the passenger side breather tube. But, the driver's side intake chamber from first pic seems to have more oil residue. What should I look at to figure out where it could be coming from? I don't have a check engine light and idle seemed fine so I don't think I have a vacuum leak in any of those tubes/hoses. I could do a catch can but I'd rather figure out why so much oil is going into the intake and leaving the oil system.

I found this to help me understand how the PCV and breathers work I believe similarly in the XF. I've read through the manual but without having seen the valve cover off the car, I wasn't sure based on the cartoon pics in the manual what it really looks like. I'll do some checking on the check valve on the driver's side. Does anyone know if the land rover pcv cap and membrane is the same for the XF? I found a rebuild kit on ebay suggested from another forum as well. I don't think one can remove the cap without breaking it so want to have a replacement in hand and not have to replace the whole valve cover.

First yes change the PCV membranes. They are side by side on the passenger side of the engine as you indicated. They are cheap but I don't think that's your problem but it's possible.
There are several guys on the F-Type forum running catch cans. I have considered it as this mod is almost universal on the US muscle car forums. Without us knowing how much oil consumption you have this all might be normal or not. You might need to assemble everything and do some more driving to see what happens.
Yes the PCV is the same between LR and Jaguar.
