7a Fumes?

[geneandbolly]

does anyone have any idea if there is a crank case breather pipe etc on the nearside of the 7a engine. i noticed faint oily fumes that you used to get on the old fords if the breather pipe if it was hanging off and this smell is identical. looking closely i can see faint traces of said fumes coming up in the small gap between the inlet manifold and the radiator, around the dipstick area where the arrow is pointing to in this photo. this is an oily fume rather than exhaust fumes.

hmm...
