Intake manifold drains?
Posted: Sat Feb 18, 2012 10:10 am
Scott,
You're right about me having the "Kimball" setup. I agree with your
overall assessment of the drain pattern with the Kimball setup.
I too thought about putting a bracket on the air box, but was convinced
this isn't a good idea due to vibration. I don't really want to put
another hole in my cowl, as you're doing. I think you could simply put
a firewall "z-like" bracket with a flexible tube, as I suggest in my
original thoughts (below) and avoid that extra hole in the cowl.
It sure is interesting to see the various options folks have. I'm still
puzzling through what I'm going to do (see below original msg).

Ted, I am just guessing you have the drain kit from the Kimball's. The
one thing I noticed about their setup I didn't like was they end up with
a low spot in the line that traps oil. Seems to me like you would only
really drain # 6 out the quick drain and the oil from 4 and 6 would go
right back into #5.
Mine are going to connect all together but instead of the drain up on #6
there will be an extra T fitting in the low spot between #5 and #6 right
above my carb air box. Then have a short tube down to a quick drain
that is attached to the air box somehow for support so I can push up on
it to open. Then I will have a small hole in the bottom of the cowl that
I can get at the drain. The hole will be about 2 or 3 inches back from
the air intake hole on the bottom cowl half.
Pictures attached.
I have seen a couple do just as you say and run a line back to a fitting
by the firewall, however both of these (Ron's is one) don't have the T
in the low spot so not really doing much good in my opinion. Seems a T
below #5 would fix.
My other thought was run all three with their own lines, all down hill,
to a fitting at the firewall.
FWIW,
Scott

Ryan,
I recall from looking at your Moose at OSH that you had two
quick-drains, one coming out of each exhaust, for your intake
manifolds.
I assume that the one on the pilot side drains cyl 4 & 5 whereas the
one on the passenger side of course just drains #6.
Questions:
- Did you just flex hose/tube off of the 4 & 5?
- Do you have the "hose" off of 4 & 5 coming into some sort of "Y"
fitting, and thence down to the quick drain?
- How do you keep the "hoses" and in turn the final quick drain from
vibrating against the exhaust?
I have been thinking of connecting the #4, #5 and #6 into a single
fitting and then, with an elbow joint, having a hose go back to a
bracket attached to the firewall so I could drain them all with a
single quick drain attached to a bracket there (obviously set up so
everything is lower than the exhaust points. This seems like too much
tubing/work/brain damage compared to, perhaps, the simpler set up that
you might have.
Currently I have one quick drain off of the #6, which also drains #4 &
#5; The quick drain I currently have can't be reached without opening
up the cowl (19 fasteners later).
Thanks for your input,
Ted
