E60 M5 and E61 M5 Touring Discussion
Hello M5 board, Mr. P asking if anyone knows reason for bore issues on the S85?
Recently purchased for a rebuild and Cyl#8 and Cyl#10 are terrible.
Also noticed an e-bay seller trying to sell block/crank with similar issues, so this must be an issue.
pics attache, want to know root cause.
