Does anyone have any information please? I've seen quite a few illustrations of 2 Litre engines where the brass breather vents in the rocker/cam cover have been fitted with - or replaced with - elbows that allow breather pipes to be fitted, though I assume these were never a standard fitment. I've no idea who manufactures these or whether they have been hand made by individual owners. I would like to acquire a couple to pipe away the slight smell of oil vapour which seems to pervade the cockpit of the car when the engine is warm. I gather from comments I've read previously that this is not an uncommon problem. Any advice would be appreciated. Thanks Chris
