January 26, 2010 - Here's a peek at where my interference problem is coming from.
The picture on the left shows how the oil filler neck is cast into the valve cover. On my engine, that same casting is fitted with a plastic plug with a vacuum nipple in it. The picture on the right is the newer design, tucking both the casting and the nipple inboard and offering more clearance for applications such as, oh, MGs with power brakes.
After talking with Jon, the V8 tech at Flyin' Miata, it'll be a fairly easy job to make the alterations I need.
