I replaced some of my tin ware but it was with the engine on the floor (out of the car). I did remove the rear tin to R&R a cam chain cover seal. Its doable but very fiddly. You have to remove the primary muffler.
I mean the tin wear nearest the rear wheels - underneath the rear seats. You see this tinware, or whats left of it, with the rear wheels removed looking towards the gearbox from the wheelarch. Sorry if I wasn't clear.
Just did mine with the engine in place, tight fit but is doable, have to remove full exhaust, rear exhaust mount and cross over pipe on the heat exchangers.
Side tinware will have to be removed to make it easy to remove the rear.
Sorry just re read your second post and see you mean the tinware near the gearbox.
Don't think that looks possible without dropping the engine or maybe lowering it a lot.

I know you can remove the rear piece and the side pieces with the engine in the car, since that is what I did when I adjusted the valves and reinforced the engine mount. You do have to remove quite a bit of stuff, and removing the rear bumper helps with access.
I am not sure if the front pieces can be removed with the engine in place or not.

Can somebody explain more on that? Is it possible to do remove/replace the front tin with the engine in place?
Removing the front tin would be very difficult if it’s possible. Few cables / hoses run through holes in the front tin, and IRRC a few bolts at the front would be very hard to get access. Easier to just drop the engine. Always something to do while you have the engine out!
I tried and decided it wasn't worth the pain and aggravation. A lot easier with the engine out - and it has to come out eventually anyway. So if someone actually did this with the engine in the car without bleeding hands and sanity intact, they are a much more patient person than I am.
I was successful removing the rear tin from a 993 but I did have entire exhaust removed and a good amount or ancillary components but I recall lowering the engine slightly unbolting the tin and lifting it away or down can’t recall .
without lowering the engine somewhat it would be very difficult to remove the front pieces as these are jammed under the body crossmember to seal the engine to the body , once lowered though you should be able to access scores and bolts securing the two that is if you don’t have a power steering pump , there is that , it will require some removal of that pump cover and belt shroud as I recall , my engine doesn’t have a pump..Bert
Here is a picture of the ‘tin’ in question. Mine has been powder coated. You can see all the obstacles if you zoom in, plus the accelerator cable which is absent in this picture. IIRC, the tin section around the power steering pump is the difficult part. I think the OP has already decided to wait until the engine is removed. I agree with OP it will be a painful, knuckle tearing job to attempt with the engine in situ. It isn’t that hard to drop the engine. And you can do the major service while you are there!
