Gary;
I'll agree with Ol' Bob and say they shouldn't be leaking and they are a
bear to get right. I've done one a few that continue to seep while others
are dry as a bone. At first I thought that one side of the engine wasn't
getting any oil! Keep pluggin' away at it!

The pushrod tube seals shouldn't leak but this definitely a common problem,
even with low time engines. I just overhauled a IO-520 engine for my
Bonanza myself and had several seals that leaked a bit. Frustrating. I
just had to replace them. They can be damaged during installation if you
don't do it right. And I have been told that you have to polish the shroud
tubes at the ends where the seals fit or they will leak. Apparently the cad
plating is just rough enough to prevent a good seal. They can be replaced
without removing the exhaust or induction tubes, but it isn't easy.
The oil fill cap seal should not have an effect on case pressure at the case
vents through a 3/4" dia. hose below the cap. The vent line should be free
and clear or you will have other serious problems, like blowing out the
crank seal.
I have not heard of the problem of the Real Gaskets pushrod seals leaking
before. I think they are guaranteed not to leak, whatever that means!

Gary,
Make sure there are washers on each side of the rubber seal so that the
seal is sandwiched by the two washers. The washers help to deform the
seal so it fits tight in the diameter of the hole. Make sure the spring
is well seated and is applying even pressure against the outside washer.
Be careful not to damage the seal when you install it.

I always pay attention to ruddervators hinges during preflight inspection by
moving reddervators alone the hinge axle to check for play. Today I noticed
some play in the right ruddervator. A closer look revealed no play in the
hinge bearings, but a very small play when reddervator is moved up & down. A
sound could be hear from within the tail cone and the play results less than 1/8
inch movement at the trailing edge of reddervator. The left ruddervator has no
play.
I did not remove the tail cone to look further since I was in a hurry to go
home. I will remove the tail cone to take a closer look in the next few days.
I am making this post to get suggestion from you guys as what should I look
for after removing the tail cone?
Thanks,

Bill,
I sent you the money yesterday (damn, I didn't know 980,00 pennies
weighed that much! Next time I'll put them into rolls so that they'll
pack easier.

Thanks for all the advice on the pushrod tubes. We took a lot of time
when we installed them and thought everything went together fine, but we
didn't polish the tubes (darn!). Once someone gets them to quite (which
will probably mean reinstalling some of them) do they stay dry?

Good Evening Gary,
I am on my third engine in my V35B and there has never been a push rod leak.
Our oldest son has changed five cylinders in the last four years on his 520.
So far, no push rod tube leaks. One of my close friends had a problem a year
or so ago. First couple of attempts by his mechanic at fixing the leak
failed. Took a bit more time, made sure everything was clean, well aligned and
free
of burrs. After that, no leaks. Do it right and they won't leak
With my luck, now that I have said that, mine will start leaking tomorrow!
Happy Skies,

Bob & All,
Do you put them in dry, or do you lubricate them? If so, what do you
use to lubricate them?
I'm definitely going to try and get them not to leak (my pride just
won't allow my Bonanza to leak oil!). Is there a certain procedure you
use? From your advice I will definitely polish everything up, but is
there any other tips you'd recommend?
Gary

Good Evening Gary,
I generally assemble them dry, but If I was having problems, I might try
using a little Dow Corning number 4. It is recommended for oil filter seating.
I
also know some folks like to coat the seals with Corrosion X before assembly.
The theory is that the slipperiness of such coatings allow the seals to seat
better.
