Realized, that the breather cover is different to later version.

Is it a sandcast only part?

Edit: Parts list says up to #10337

Higher by about 5mm, inside without enforcement.

Later cover will not fit to sandcast valve cover.

Here you see K6 and SC engine to compare valve cover (note that different edge just under the breather cover) and the breather cover backside.

Will have to paint that breather cover.

What would be best color to match correct finish?

KP noted the distinction on the breather cover a number of years ago.  if you search in Mark's 97 build, you'll find the Duplicolor paint type he used.  i'm not at my shop now, i can't remember what color is used on the cover, in the USA it's a Duplicolor paint product.

Regarding the 2 engine mount nuts on the front right side (hanger bracket). # 94001-08000-0S


According to Marks list, those are 8 x 1,25 x 12.

Only 12, is this correct?

referring to the 69.4 factory parts book:

item 9, pn 92200-08056-0A, BOLT, hex., 8x56, quantity 2.

the 3rd larger bolt, item 10, pn 92200-10050-0A, BOLT, hex., 10x50, quantity 1.
