I was concerned about this after my latest modification. This project
started with the oil drain having an oversized plug so I can not put a
VDO oil temp sensor there. See:

         Here I am test fitting the parts on a spare block. I eliminated
the oil filler tube and in the vacated hole I mounted a plate I made with
the new VDO oil temp sensor. Great, but now I had  to come up with a new
way to add oil. I combined a couple of high performance Type I parts from
CB Performance and replaced the plastic breather tower with this aluminum
tower you see in the picture. It has both a vent and a oil cap.

         So far so good. With 218K+ miles on the engine I thought blowby
might be a problem. In reality I think the amount of scavange is metered
by the in line metal plug (digifant only) with the small opening through
it. So a straight through tower might not increase the air flow. Just  a
thought.

Good Luck and Drive Safely
