Wot, no comments - still ??
Please understand, I dont sell any sets but wanted to share my idea with those
who like the purely mechanical way. So feel free to include this idea of unlocking
the oil valve from the fuel shut-off by Bowden cable in your own design that
may look quite differently. But then, you will need some metal working facilities......
Cheers

LOOKS REALLY NICE! I PUT A BALL VALVE ON MY RYAN STA YEARS AGO WHICH WORKED WELL.
I WAS LUCKY THE OIL LINE WAS LOCATED IN A POSITION WHERE THE BALL VALVE CONTROL
HANDLE WAS ACCESSED AT THE REAR OF THE COWLING. IN THE OFF POSITION THE
HANDLE STUCK OUT IN PLAIN SIGHT, AND I ATTACHED A RED STREAMER TO IT AS AN ADDED
PRECAUTION. I KNOW ANOTHER GUY WHO DID THE SAME THING BUT HAD A DOOR IN THE
COWLING WHICH COULD NOT BE CLOSED WITH THE VALVE CLOSED. (CONTROL HANDLE STICKING
OUT) YOURS LOOKS VERY NICE. MIKE

Hi guys and gals I'm doing my condition inspection now and on the to do lis
t is adjust the valves well after draining all the oil and removing-the o
il hoses let drip a couple days time-for the valves remove the covers and
another quart or two of oil-from the lower cylinders valve covers. So my
question is how do you know if its the oil pump ball seat or a valve guide
that's not quite up to par creating the hydraulic lock?. All this talk abo
ut ball valves after the oil tank and before the oil pump maybe we need to
get the oil out of the push rod tubes? Has anyone put a drain tube on the v

Hi Bill,
you are quite right with all those oil filled valve covers. I suppose this may
add to the oil consumption but dont think it could lead to hydraulic locks. Most
radials do collect all oil from valve covers down to the bottom oil tank via
hoses, not so the M 14. I was thinking about this mod for the M 14 but could
not come up with a neat solution while the engine is in the plane. Anyway, I
believe most of the valve cover oil will stay there and only a minimum of it will
find its way into the cylinder, unable for all of it to collect in one pot.
But a leaking check valve in the oil pump will fill the crankcase and lower
cylinders in time. So some sort of shut-off valve is a good idea and I like my
design for its easy use. Basically it is mostly a hacksaw-file-band sander job
with some easy lathe items, and some fitting time as well. Just the right thing
for winter days in your home workshop, if you take pride in metal working.
Cheers
Vic

Bill,
All you have to do to prevent a hydraulic lock is take out the spark
plugs. That leaves a VERY BIG HOLE, that the oil can flow though. And yo
u
really only need to do it on the bottom cylinders.
Also taking off the valve covers will NOT cause a hydraulic lock. One.
there is not enough oil in the covers. Two. the oil will not flow into the
cylinder, it simply falls on the floor OR a bucket/pan. All the valve cov
ers
in total would not have more than quart in them.
Do not worry about the oil pump ball valve or seat. Simply drain all the
oil from the oil tank (you're changing it anyway). Also you'll be taking
all 4 oil screens out to check and clean, so the engine will be draining o
il
anyway.
If you don't have a A&P license and have done this before, PLEASE get a
qualified guy to do it for you and watch.

I BELIEVE THE LATE LES CROWDER HAD VALVE COVER DRAINS, AN OIL SHUTOFF
VALVE, AN ELECTRIC POST SHUTDOWN SCAVENGE PUMP. AND INTAKE DRAINS.
WORKED GOOD. LOTS OF WORK.
