Parts Needed
Mandatory:
1x Sump suitable for mk1, you can also put on a used sump but that will take more time to remove and clean old gasket sealant from it
1x High temperature gasket sealant
1x Cloth
1x Flat screwdriver
1x Wooden Wedge
1x Spanner/socket wrench in the following sizes:
10
13
1x Allen key for socket wrench or normal one, size 12
Optional:
Since you have to drain the oil anyway i advise to change oil + oil filter aswell, unless it was changed recently
1x Wire brush for drill
1x Battery drill
1x Brake cleaner spray
1x High temp spray paint
---------------------------
Sump tightening torque: 10nm

Removing bad sump
First drain engine oil by using allen key size 12
Remove all size 10 nuts/bolts from sump, since you will throw this sump away, for faster removal you can hammer a screwdriver in it and pull it down ( be careful not to stick it in where oil pickup strainer is- seen on pic named oil pick- left side ), you can also hammer a flat screw driver or wooden wedge in it and pry it away from engine block, again be careful not to damage the block
Preparing/Cleaning sump area
After you have removed the old sump and oil is still dripping down you can prepare everything for new sump to be installed.
I found it easier to remove crankshaft pulley, gearbox metal plate and exhaust manifold when fitting new sump, you also gain more space.
Also remove bottom exhaust holder bolt so exhaust can be lowered even more and completely out of the way.
Now bring your battery drill and wire brush and start removing old gasket sealant from engine block, paying extra attention to corners
After all gasket sealant is removed, get a cloth and start wipping till surface is completely clean, after that spray it with carb cleaner and wipe with cloth again, repeat it few times till cloth is clean when you wipe the surface. Try to remove sealant from inside bolt holes in block.

Get your drill + wire brush out and start cleaning, degrease with brake cleaner, wipe with cloth till clean
My donor car sump had rust spots on it so i had to remove them with wire brush and paint sump afterwards ( if i knew how much time cleaning, removing and painting this used sump will take i would buy a new one, but i saved some money)
First i painted it with black high temp spray can twice and after it dried i painted it in white color (good for noticing leaks).
Installing new sump
Wipe surface area one more time to ensure there is no oil or dirt on it
Apply a thick bead of gasket sealant on sump all the way around completely covering all bolt holes too, ( dont save it and be more generous on corners).
There are 2 methods of using gasket sealant, first one is to apply it on sump put it on and screw the bolts down to specified torque (10nm), the other one is to apply it on sump, screw bolts till gasket sealant appears, wait till it dries and then torque down bolts.
I used first method, but probably doesnt matter which one you use just that it doesnt leak.
Second method explained more in clip its not for punto but same principle.
While you are waiting for sealant to dry, you can put everything back together.
When everything dries go for a ride and check for leaks.
Dont forget to pour in oil afterwards
