Hi All,
I think I may have suffered the dreaded hydraulic lock! My Nanchang had sat idle
for about 4 or 5 months. Before attempting to start it I pulled the lower plugs
(front ones only), got a fair bit of oil out and pulled through about 12 to
15 blades. When I tried to start her the prop turned about a half dozen times
with a bit of smoke and a bang as it started to fire then abruptly stopped.
Checked the prop and it was locked solid. Fearing the worst I pulled all the front
plugs and intake drains but I was surprised that no oil came out. Also the
prop was still locked in position, I had assumed once the plugs were out the
lock would release. Can anyone tell me, does this sound like hydraulic lock?
How come no oil came out after and why is it still locked up with the plugs out?
Also if it is a hydraulic lock is the motor repairable or throw it away?
Thanks for any ideas or info.
Mark

I would be almost certain that it is locked because a connecting rod bent;
the piston moved further up the cylinder and the oil control ring jumped
out, and it is now preventing the piston going back down the cylinder.
Sorry, so not good news. But, the motor is repairable, but should be very
carefully checked in case there has been a major strain on some component.

Unfortunately, I think a number of people would remove the cylinder in
question, and confirm that what I have suggested is correct; remove a couple
of other cylinders which will give you access to the crankcase; remove the
bent rod, which you can do unless it is the master rod; replace the rod and,
probably, piston and reassemble.
My personal view is that a hydraulic lock imposes quite significant strains
on the crankshaft and possibly crankcase, and I personally would want to see
the crankshaft and case being removed; x-rayed/crack tested; check that it
is completely "true" it is of course only pressed together; carefully
check that none of the other cylinders were affected, and then, very
importantly, make sure that the new piston and connecting rod weigh within
half a gram of the others.

The longer you leave the engine, the greater amount of oil is likely to
migrate down from the tank. Also, I noted that he only pulled one lot of
plugs; you can get oil in the intake tubes (but more likely with a tail
=93 wheel aircraft); you can have oil stuck in the bottom of the
inverted piston etc. After that length of time, I would turn it through
at least 50/60 blades with the plugs removed. Also, it is a very good
practice to make a note of the oil level on shutting down, and leave
that in the aircraft. When you come back, you will then know how much
oil has gone into the engine!

Richard, do you think this problem has been caused by the lack of use
for 4-5 months or is this just a coincedence. If Mark has pulled thru
and pulled plugs, what more should be done?

Thanks for all the info Richard, its much appreciated. Is there an easy way to
tell which piston is the problem? Also how do you think it would compare price
wise between doing the work you have suggested and replacing the engine.
Anyone know the going price for a replacement HS-6A?

Typically not a master rod. But definitely could be a bent link rod in probably
#5 or #6 cylinder. If the link rod is bent, it will jam up against the sleeve
of the cylinder.

Many CJ owners do not install intake drain kits on the Housai engines. Mos
t =0Alikely because the Housai engine does not have intake plugs on the #4,
5 and 6 =0Acylinders as does the M14 engine. Oil does collect in the intak

drain. This helps flush the oil from the =0Aintake tubes. Then pull the

a slightly nose high attitude on the ground, =0Ait is always recommended to
pull the rear spark plugs because the oil typically =0Arests at the rear o

The longer you leave the engine, the greater amount of oil is likely to
migrate down from the tank. Also, I noted that he only pulled one lot of
plugs; you can get oil in the intake tubes (but more likely with a tail
=93 wheel aircraft); you can have oil stuck in the bottom of the
inverted piston etc. After that length of time, I would turn it through
at least 50/60 blades with the plugs removed. Also, it is a very good
practice to make a note of the oil level on shutting down, and leave
that in the aircraft. When you come back, you will then know how much
oil has gone into the engine!

As well as what Richard said. The 5th ring counting from the top of the pist
on, with the connecting rod bent, on down stroke slipped out of the neck of t
he cylinder. On up stroke that ring jams on the throat of the cylinder locki

The YAK maintenance manual calls for this if the engine sits idle for thirty
days. "Drive out the intake plugs and spark plugs". They also recommend th
at if the engine sits longer than five days to pull blades periodically to c
lear any accumulated oil.

Well guys, We parked our DC3 last October and carefully installed drip
pans. In March when it was time to get her going again, we removed all
the bottom plugs pulled her through then started it up without the
bottom plugs installed. Ran funny and shot a lot of oil across the ramp,
but no hydro-lock. I learned this trick from some =9DOld
Timers=9D (as I am approaching 70 myself, that means anyone who
is older than me!)

Hi Dennis;
The Huosai does indeed have intake drain plugs on 4, 5 & 6. These are
identical to the ones on the EARLY M14P with one major exception. The
plug bosses on the Huosai intake pipes are welded directly to the pipe
with no re-inforcing doubler as you will find on the M14P.
As a result the addition of a drain system introduces the possibility of
cracking around the boss unless the pipes are modified to the same
standard as the M14P.
Cheers;
Walt

Subject: Re: Yak-List: Re: Hydraulic lock?
Many CJ owners do not install intake drain kits on the Housai engines.
Most likely because the Housai engine does not have intake plugs on the
#4,5 and 6 cylinders as does the M14 engine. Oil does collect in the
intake tubes and it does thicken while it lays in the intake tubes. If
a glob of oil gets sucked into the cylinder, it could be enough oil to
cause the dreaded hydraulic lock and also cause a link (connecting) rod
to bend.
Therefore, one of the ways to help prevent hydraulic lock, besides
pulling the plugs and pulling through, is to install an intake drain
kit. Leave the intake drain kit open when the aircraft is parked.
During the preflight prep, with the intake drain open, pump a few shots
of prime and watch for the fuel to eventually run CLEAR out of the
intake drain. This helps flush the oil from the intake tubes. Then
pull the blades with the intake drain open.
Also, because the airplane sits at a slightly nose high attitude on the
ground, it is always recommended to pull the rear spark plugs because
the oil typically rests at the rear of the cylinder due to the nose high
attitude. Most importantly, pull the rear plugs from 4, 5, and 6. Even
#7 can't hurt.

Ahhh....learn something new every day. The reason I said what I did was
because of the many CJ's I have seen, very rarely was there any intake
drains installed. Now I understand why.

The M-14 Engine has slightly different "stroke" lengths, and I would
guess so would the Housai. You cannot rely on that method all the time.
Just sayin. It sounds good in theory, and with a V-8 Chevy it would
work. Not so this engine.

pulling cylinder you got the correct one. Stroke is 5.11 inch's so there sh

the bore and if it is in-fact locked as Mr Goode-has suggested it would

| Subject: | Re: Hydraulic lock? |
Everyone else has responded to this already, so there is not much more to be said......
except:
One thing I have discovered with my YAK-50 that DOES have the intake drain kit
installed, is that when the weather is cold, the oil does not tend to just run
right out of the intake drains. This results in the strong possibility of oil
remaining in the intake tubes and being gulped right into the engine on start,
which apparently is what happened to this poor gent. And yes, I am running
Phillips 25W-60W Radial Engine Oil.
So to those with intake drain kits installed, take note if you choose. I first
prime the living daylights out of my engine and DO NOT (!!!) pull it through
AT ALL!!! I just sit there watching the intake drain itself. What SHOULD happen
is that raw fuel comes streaming out of the drain. If it does NOT do that,
then "YO" the oil in the drain tube kit itself is backed up and you might still
have a lot of oil (and now fuel too!) in the lower intake tubes themselves.
This is a strong DANGER DANGER indication!
At this point, I prime it still more and AGAIN watch the drain. If STILL nothing
happens, I pull the front and rear plugs, and then start pre-heating the whole
darn engine no matter what it takes to accomplish that. STILL never turning
the prop at all.
Eventually all the oil and fuel will come streaming out the intake drain. THEN
and only THEN is when I will consider pulling the prop through.
If you don't have the intake drain kit installed, you are looking at pulling the
cowl and the plugs and pretty much doing the same thing.
The YAK-50 being a tail-dragger is especially prone to this happening. Point
being, even with the intake drain kit installed, you still can't take it for granted
that it worked as advertised.

The YAK maintenance manual calls for this if the engine sits idle for thirty days.
"Drive out the intake plugs and spark plugs". They also recommend that if
the engine sits longer than five days to pull blades periodically to clear any
accumulated oil.

The longer you leave the engine, the greater amount of oil is likely to migrate
down from the tank. Also, I noted that he only pulled one lot of plugs; you
can get oil in the intake tubes (but more likely with a tail wheel aircraft);
you can have oil stuck in the bottom of the inverted piston etc. After that length
of time, I would turn it through at least 50/60 blades with the plugs removed.
Also, it is a very good practice to make a note of the oil level on shutting
down, and leave that in the aircraft. When you come back, you will then
know how much oil has gone into the engine!

Richard, do you think this problem has been caused by the lack of use for 4-5
months or is this just a coincedence. If Mark has pulled thru and pulled plugs,
what more should be done?

As usual, Mark - you are right on the bullseye here. What you described is
exactly what happened to me a couple weeks ago when I started the Yak for
the 1st time in months. It was chilly out and I had left the intake drain
open the entire time she sat. The only time anything moved through the
chilled drain tube was when I would cycle the drain valve - then a single
globule of oil would exit after each opening - guessing the slight vacuum
on the clogged line caused that. About 15 minutes after priming - with the
valve still open - the fuel worked it's way through the line and opened
things up - I guess much like an oil dilution system would do. I have MUCH
to learn about these aircraft / engines. But if you experts have taught me
anything, it's be careful to the point of PARANOIA w/ start up. Thank you
for that. I'd rather take the time & effort and be mildly inconvenienced
any day over being grounded w/ expensive and lengthy repairs due to
complacency.

Roger that Mark. That also is why I jack the tail up after I put her up for the

> So to those with intake drain kits installed, take note if you choose. I first
prime the living daylights out of my engine and DO NOT (!!!) pull it through
AT ALL!!! I just sit there watching the intake drain itself. What SHOULD happen
is that raw fuel comes streaming out of the drain. If it does NOT do that,
then "YO" the oil in the drain tube kit itself is backed up and you might
still have a lot of oil (and now fuel too!) in the lower intake tubes themselves.
This is a strong DANGER DANGER indication!

> At this point, I prime it still more and AGAIN watch the drain. If STILL nothing
happens, I pull the front and rear plugs, and then start pre-heating the
whole darn engine no matter what it takes to accomplish that. STILL never turning
the prop at all.

and only THEN is when I will consider pulling the prop through.

the cowl and the plugs and pretty much doing the same thing.

being, even with the intake drain kit installed, you still can't take it for
granted that it worked as advertised.

if the engine sits longer than five days to pull blades periodically to clear
any accumulated oil.

down from the tank. Also, I noted that he only pulled one lot of plugs;
you can get oil in the intake tubes (but more likely with a tail wheel aircraft);
you can have oil stuck in the bottom of the inverted piston etc. After that
length of time, I would turn it through at least 50/60 blades with the plugs
removed. Also, it is a very good practice to make a note of the oil level on
shutting down, and leave that in the aircraft. When you come back, you will then
know how much oil has gone into the engine!

4-5 months or is this just a coincedence. If Mark has pulled thru and pulled plugs,
what more should be done?
