Too much oil in engine. A problem?

[bor]

Mrs BB once filled her car up with oil and then forgot to screw the filler cap back on.

One of our cam-cover designs, maybe the N52, had a baffle underneath the oil cap opening to avoid this problem. On another of the designs, the cap itself was on a hinge to at least keep it in the right location.

When I looked the problem revealed itself. The dipstick is exceptionally difficult to read and even with over 50 years of fiddling with cars, I struggled. I ended up having to 'swab' along the stick with kitchen paper to confirm the oil I thought I could see... It's basically a long coil spring which seems designed to hide the oil on its surface.

Yep, that sounds exactly same as my Mini (as suggested in post #10). It's even harder to read when the oil is clean!
