Had a problem with the V8 engine on my BMW 740i. The BMW V8s
originally came with aluminium cylinder liners. It was found these were
affected by (if I remember correctly) the sulphur in petrol. These
eventually caused a failure in my engine (well, when my father owned the
car). The liners were replaced with steel ones. Apparently BMW were
supposed to fit these for free, but since we didn't have a full BMW service
history, my father had to pay...not cheap!

By the way, is this the process you're talking about?

Looks like if you want to see if it works over time, watch some
Mercedes cars...

We've had aluminum auto engines without liners and as I recall they
had a pretty high cylinder failure rate?
