As stated above, that argument only applies to an iron sleeving process. What we are talking about is cutting a hole in aluminum and sleeving it wil the same aluminum, in the form of an aluminum sleeve. I would never ask for a single sleeve of different material, that would in fact compromise the block. The other shops I’ve spoken to today have confirmed a single aluminum sleeve would be the least invasive process.
Please read page 30 of the PDF I linked above from one of BMWs main suppliers if you aren’t understanding the procedure I am having done to my 8th cylinder
