Removing 1967 273 Dipstick Tube Without Damaging It?

[Bossanova5]

How do you remove the dip stick tube on a 67 273 block without damaging it?
It can't be pushed back from underneath as it bottoms out in the block and is not accessible
Thanks

If it was me ( and it will be some day)


First... Measure the length from the base to the open end for future refrence

I would get a steel rod that fits snugly inside the dip stick tube

Then fabricate a rectangular block split in half like a torsion bar puller.

Insert the rod, clamp the clamp on the outside and lightly tap the tube out.

Awesome idea.
Unfortunately, I don't have a lathe, mill, welder or other machines available to fabricate the tool.
Thanks

Pan is off, can you not size a punch to knock it out from below?

 

[Dana67Dart]

Block off steel and a drill and some bolts and nuts will work great.

You could also put the rod in and use a small hose clamp around the outside and tap on that

Hopefully you can get it out but if it gets damaged Mega Parts has new ones.

The dipstick comes out of the block at an angle through the hole identified in the picture. You can't even see the dipstick tube from the underside of the block at all.

No way they made that hole with a curve, so an appropriate size punch should work.

i've punched them out with a push rod before.

or you can use vise grips and a rag around it to limit the damage and give a little tappy-tap and it should pop right on out.

i took a pushrod , turned end down to fit , drove it out from the bottom

I have pushed out probably 30 of them without damaging them. Drop the pan and use a bigger size screwdriver and cut off the flat or phillips end. The size of the screwdriver needs to be exactly the same size as the hole. Then use the "former" screwdriver and a hammer and punsh it out.

As I remember a common 5/16 bolt is the same size and the tube will come right out by tapping with a small hammer.

If it need to be removed from the top, I just put a tapered punch in place of the dipstick, wrap some electrical tape around the end of the tube, grab it with some small vice grips and twist it out. This assumes the tube is in good shape. If cracked, it will probably break off. Then its either tap out from underneath, or, run a tap into it and remove it that way. New ones should be available depending on the length of yours.

Take a 5/16 or 3/8 shouldered bolt, depending on tube dia. - a longer bolt with the thick un-threaded section, slide it into the tube as far as possible, use vise-grips or similar pliers to pinch the tube to the bolt, - twist and pull.
I used to replace Sears rebuilt engines, all breeds, - that worked every time.
Tube may be very slightly oval where pinched, just adjust with pliers as nec.

 

[cudamark]

that's why I use the tapered punch. It fits tight against the tube so it doesn't deform.

Lol, it only fits tight at the top interference, being tapered it will deform below that where it's gripped.
In my experience, the bolts fit amazingly snug, especially the shouldered/unthreaded area for a continuously supported area to pinch with a tool.
If you squeeze the tube 90* with the bolt still inserted, it re-conforms to round.
Pushrod works good too.

 

[cudamark]

You don't grip it below the lip. Just grip it right there.

From your picture, it looks like the oil pan is off, so you can drive it out from the bottom. I had to do this very task on a 360 today.

I took some pictures of the task and the tool I made for it in the past. My tool is similar to the suggestion of using a screwdriver or a pushrod, but I made my "tool" using a 5/16" bolt with the threads cut off,and the end ground flat and perpendicular to the shaft.

Place an 11/32" box end wrench on the bolt, in case it gets stuck, to knock it back out. Insert the tool in the inner hole through which the dipstick enters the oil pan. Using a small hammer, for better control, tap the tube out.

Light, precise taps, while holding the bolt shaft to feel for anything not moving as expected, are better than heavy taps. Some side pressure on the shaft might be needed if the tool is not catching the edge of the tube well.

This tube was tight in the 360, but it only took eight or nine taps to knock it out, with no damage to the end of the tube.

I use an old valve with a 5/16 stem to knock them out. No idea what the valve came out of....I've had it since I was a teenager and it's only job is to knock dipstick tubes out. @Vaanth Thanks for the 11/32 wrench tip. Good idea!

I didn't have the right combination of tube dipstick combination in a car i bought and wanted a new setup...from Mancini. I shaved a trim removal tool down to slide under the shoulder of the tube at the block. Tapping it under gently with a hammer and turning the tube to pry it out.
