After the rather nice maintenance of the injection system and having taken appart and put together with success a substantial chunk of the engine, its time to do some more homework.
I want to preliminary change the water pump, belts and the infamous foam seal between the two front covers.
I plan to take the bonnet out but leave the radiators in place and just go bit by bit, like I did with the injection, this time not trying to save time or expense.
I looked at N° 73 of the Tee One topics and that foam seal does not good very reliable. It's there all hot and made of porous material. It looks made to perish.
Is there any alternative, such as modern silicone materials? cannot you just seal it externally after replacing?
Additionally, what else would you do there, other than overhauling the obvious viscous coupling, belts, etc...
I was thinking of the alternator and the steering pump, but these are quiet easy to access would they fail later and seem to be pretty reliable.
Input very wellcome.

My God, Lluis, you even read Topics?? I better start writing again!!!!
That strange soft extrusion at the front of your enghine has been doing its job for over a hundred thousand engines without problems. It is little work to change, it is sure to fix your leaks, why in the name of God would you try to improve it?????
I am quite proud of you; as you write as if you may have graduated from the platoons of undergraduates to the Opening the Door Course which we try to run here! All strength to you my lad.
Certainly remove the bonnet which takes two of you. To not do so would like trying to repair one of your teeth via your rectum!. While you are there (the front of the car that is) you should replace the seal on the water pump - get someone to do that for you it is a bit tricky without the right gear, Pull off the power steering pump. empty it and clean it. Again if it leaks or you think it is noisy give it to a specialist. The alternator probably needs new brushes and bearings and checking generally and the front engine mountings are well on the way to being rotten. All coolant hoses replace and give the whole system a good flush, a new thermostat and coolant and replace the transmission cooler hoses to the bottom of the radiator.
Finally give the whole front end a bloody good clean, check all the floppy wiring in the area and put it together again.
Again be happy with the Factory seal.!

The job is done, took me four week ends.
I can only recommend indeed taking the bonnet out, as it made everything much easier.
Resuming: Indeed I changed everything for orginal items, which included a myriad o-rings, seals and stuff fromthe turbo, to the turbo, et al... some pipes (downpipe) were a pain to re-fit but all in all it turnoed out to be a marvellous improvement.
In eight weeks, whole engine top was dismatled to re-seal everything, injectors were ultrasonically cleaned, new fuel pipes were fitted, new water pump and all sump bolts re-tightened.
All in all a lot more work than it seemed (it's the "modern-looking" engine.
What an improvement, 60mm Hg vacuum and steady when warmed up and virtually inaudible idle.
