Just another overhaul thread

[Surcouf]

And so a few questions (new and pending answers):

Question 1: I removed the oil sump, without removing the reversing gear housing, just loosening the lower 3 bolts on the rear flange. Am I now obligated to remove the large nut at the back to change the round rear flange gasket?

Question 2: If the question 1 answer is yes, while I am doing so, is it a lot of work to change the rear thrust bearing and the rear oil seal, and can it be done without removing the reversing gear ?

Question 3: in the previous post with pictures taken after removing the head, are these block damages? or typical and normal?

Question 4: see my distributor question above. Is that a bad decision?

Question 5: question on corrosion in previous post

Thank you for your help!!!
