So I tried to replace the o-rings on the push rod tubes. I was able to pull 3 out of the 8 tubes using pliers but I cannot believe that there is not an easier and more efficient way of pulling those tube out. Not saying that using pliers, even when being careful, there is a risk of damaging the tube.

Does anyone know of a tool to get them out? I would see some kind of expanding device that fits inside of the tube with a kind of slide hammering device to get them out. I am pretty sure that someone that does this routinely will have a tool!

I have had pretty good luck wrapping a shop rag around the push rod tube (360 degrees) and with a pulling a twisting motion, the pushed will pull out. No damage to even the thinnest push rod tube

Get them to rotate first, I use lots of WD/40 here.

If I can "break them loose" 1/2 the battle is won!

The rag idea is a good one as well!

Not helpful to your immediate problem, but I'm a big fan of Chris' stainless PR tubes with a welded ring against which to leverage them out. They seal nice, too.

I crack them loose with a pair of vice grips by twisting first to break the friction and then slide them out. You can put a rag around the tube so as not to mar the finish, but has never been an issue for me.

Tried again this morning with a rag but still not able to pull them out. Made sure they were turning freely before trying to pull them. Maybe my rag is to ''soft'' or I am not wrapping right!

Anyway I will put that on the ice for now and work on something else.

(IMG:style_emoticons/default/agree.gif) that's what I use ,if they don't work most likely some clown has gunked them up with sealer that is not required , seen it many times (IMG:style_emoticons/default/sad.gif) .
Buy the correct seals for your motor and lube them with engine oil and locate in the bores then push and rotate ,the last bit may require the waterpump pliers for them to pop in ,you will be good ,cheers.

Pliers were the tool I used with no luck! Will make another try before putting the engine back in the car.

Before reinstalling them with the proper viton O-rings, make sure the bores in the heads are perfectly smooth to ensure a good longterm leak free engine. (IMG:style_emoticons/default/smile.gif)

You have no choice
You should not put the motor into the car now that this tube is molested
It will leak for sure

Replace it
Buy a new or clean used one

Screw the rag
Clamp down and grab it
Ignore the damage to the tube
Get it out
Clean the rtv that the idiot used to install it
Put the replacement tube in with viton seals and no rtv

(IMG:style_emoticons/default/agree.gif) Solid advice. Sounds like the voice of experience.

I grease the crap out of the O-rings with my Smurf grease.

OP, some bottom feeder probably glued those with something.

You have to change that crap now. Get another set of tubes if yours get trashed.

The bores they fit into in both the case and the heads should be spotless with zero ridge in them.

I have had pretty good luck beating them back into shape after damage on removal. Just slid a deep well socket into em and beat them with a dead blow.

I will probably get back at it this week end with my son. A fresh set of eye and hand could be what I need!

It is difficult to fit pliers or vice grips between the pushrod tubes. Hose pliers will grip the circumference of the pushrod tube.

Just to close this, I finally ended up buying a set of tubes before trying to get the ones currently on the engine out to replace the o-rings.

Was finally able the get all of them out, made sure that everything was clean and reinstall a mix of new and old tubes with brand new o-rings.

I was able to salvage a few tubes that will go in the spare parts box.

We will see once I get the engine back in the car and get it started to see if there are still leaks.
