Number on case

Post by deyoung2837 »

Does anyone out there know what the number cast into the top of the timing case on R52, R62 and possible R11 S1 mean?
Most seem to have a smooth case, but some look to have a 3 or a 4 cast into it.

Thanks for any information.

My R52 has a 4 on it, and I think Erik Bahl's R63 also has a 4. I don't know the origin, but I would guess it identifies the company that did the castings, or maybe if BMW did the casting, then it's the casting mold number. Just a guess.
