Any tips on removing the oil filler tube on a 455 Olds. Tried heating the block with a propane torch, no luck. That sucker is in there tight. I don't want to destroy it, just remove it. Thanks.

 

If i remember correct it was just to pull it up in my 425 , sealed with an o-ring. Maybe it´s different
on a 455 ?

 

There is no o-ring. The tube is simply pressed into the block. The only thing I've found that works is to use an exhaust pipe expander inside the tube with a slide hammer to get it out without damage.

 

Unfortunately, some tubes can be a bear to remove.

(1) Drizzle some 50:50 (ATF:Acetone) along the edges where the tube inserts. Then, some dead-blows to all sides of the tube w/ a hard rubber mallet hammer or wood hammer while pulling upwards. Wrapping a piece of fabric (cotton) around the tube can assist w/ chances of denting the tube but dead-blows against the base of the tube are preferred. Patience is key - it takes some time.
(2) Turning a hammer upside down inserting the handle into the tube & rocking the hammer handle until the tube works its way out can be a good method. Again, slight drizzle of ATF:Actone around the edges can help to loosen things up.
(3) Try using a piece of wood against the base of the tube w/ dead-blows against the piece of wood sometimes works.

EDIT: The other "option" is channel lock pliers to twist it out. Wrap a piece of cotton (t-shirt?) around the tube to help eliminate marks. I still prefer a hammer method. Patience.

 

I’ve always used the same method as the “Chief’s” with success without damaging the tube.

 

I have used a wooden broom handle & using circular motions.

 

I smack them with a rubber mallet in all directions while pulling up. Some of them are almost impossible to remove without ruining them.

 

True. I can usually get them to move with a few good love taps with a deadblow hammer to rock the tube back and forth hard enough to know it hit but soft enough to not dent the tube. If it's really stuck, all bets are off and bending it up won't be a problem if need be. But This is why I have about a dozen NOS tubes stashed away.

 

Was just thinking about that also, got an idea for a tool....

 

A blind hole bearing puller may fit the bill.

After I posted the picture, I noticed this was a poor example. The collet tightening nuts shown are WAY oversized in comparison to the collets. I have a version where the tightening nuts are much smaller in "diameter" compared to the collets.

 

I put a long piece of pipe into it and wiggle front-back-right-left etc. until it comes out. Reinstall with a bit of RTV. Back in the 70s I used up some NOS ones, but quit that practice after a bit.

 

I used a hex nut which fitted flush inside the upper end of the tube. Then used a grip vise to press the tube to the nut. After having added some WD 40 or similar on the bottom end where the tube goes into the block, you can usually turn the tube with the grip vise. After some turns (lightly pulling upwards) you'll be able to takei it out easily. In case the nut should fall into the tube accidentally , just use an 1/2" socket extension to pull out the nut again.

Just my two cents, but worked fine on my 425.

 

No matter how you get it out you are going to deform the tube that goes into the Block. to fix it just take a wrench socket that's as closest as possible in size of the ID of the tube. then gently tap it through and it will fix the deformities

 

You got to wiggle it, just a little bit.
