What's interesting is that the factory repair manual mentions, shows a photo, 20mm from block to top of tube. Just like Luis; but you can't make out the steel ruler to see if it's just a typo.
If you put 6 quarts in you're full with a new filter. If you put 6 quarts in and as I do when changing the filter add some in the filter can to help avoid dry start then you're overfull.( Not by much-1/4 of a quart.) But if your filter was full, you're definately overfull.
Now the question is what type of dipstick? Mine has a zig-zag portion, meaning it aint straight and you twist it in to a final position.
Did you change the oil pick-up from the old motor when you used the e9/e12 pan? Did you block/ plug the bypass port on the B35 to use the early bottom bolt filter and not have low pressure?
