Getting ready to do the Ken Lewis modification that moves the oil
temp VDO aftermarket sender from the drain plug to the oil filler
hole by making a block off plate for the sendr to screw into.  By
getting a Type 1 aftermarket tower from Clauds's buggies or Empi, I
can fill the oil from the old generator tower localtion as the unit
still has a 1/2" breather nipple to go to the air system.

My question is:  Last night I was removing the oil fill tube pipe and
proceeded to stick my finger down  the hole and didn't feel a lot of
drop before I hit the bottom of the crankcase and that got me to wondering.

1. If the engine holds almost 5 qt.of oil when full, if had removed
the oil filler pipe with the correct amount of oil in the crankcase
and the vehicle level, would any oil have run out the hole in the
block?  I'm not math whiz on calculating volume etc. but looking at
the space available for the oil in the sump, I would think that the
oil would come up above this hole.

2.  If the oil level is above this hole in the block, then wouldn't
climbing semi-steep hills send oil up the filler tube since there's
no baffle(at least on my van?

3. If he level is under the hole in the block, how would the new
location for the temp sender get an accurate reading if it was rarely
if ever immersed in the sump oil?

I'm kinda in Ken's line of thinking that having the sending unit
double as the drain plug becomes a little "exposed" down there and if
the cost for moving the temp sender to the rear of the motor is
simply having to open the hatch to add oil, then I think it's worth it.

Any feedback form the group would be welcome!!
