Engine Detailing

[Ron500E]

Not sure if this should be in this area or the Engine area...

Does anyone have, or know of, the finish on the fasteners, as well as other parts, on the 65 230SL's?
I believe the fasteners are zinc dichromate but those holding the oil pan seem to be cadmium.

The block was black but what about the head?
The oil sump was natural aluminum and the pan black.

Looking for a guide as to what finishes were used when it left the factory.

Thanks,
Ron

The head was not painted.  Have a poke around the Wiki tech manual for many good photos.

Thank for the info. it helped quite a bit.

What I am specifically looking for are the finishes on certain components such as fasteners and the various lines as well as tubing.
Sort of like an accurate version of the "Original" book.
To the best of my knowledge, which is limited to say the least, many parts were cadmium plated with a zinc dichromate finish on top.

Also, it appears that the various sand castings, as opposed to die castings, were left in raw untreated aluminum. The die castings may have been given a coat of some type of sealer. But that's just a guess, nothing more.

The fasteners seem to have been a mix of cadmium and zinc over steel while the studs were just left au naturale.

MMCC still has a good assortment of the older stuff, including copper and aluminum washers, various M fasteners, hollow bolts and ends, etc., etc.
