Dip Stick Tube: Removing from Engine Block Without Damaging

Here is another one of the tricks I learned over the years and included in our March 2013 Newsletter and will share here:

 

Removing the Oil Dipstick Tube

by Jason Edge

This might seem like an easy task but removing and installing a dipstick tube in an engine block without damaging the tube is not that easy, but I have a sure fire “trick” that I will share with everyone.   The problem is if you just try to grip the tube with pliers and twist and turn out, or even worse take a hammer and punch out from the bottom, you are guaranteed to damage the tube.  

For removing the tube, the trick is to take a deep set 11mm 12 point socket and slide on the bottom of the tube, and gently tap the socket with hammer, pushing it out.  You will be able to remove the tube up to a point before the lip of the socket hits the bottom of the block.  You can then take an 11mm open end wrench and put around the tube next to the seat ring and tap the wrench head with hammer to drive the tube the remainder of the way out. (Note: if tube is sliding out nice and smooth with deep set socket, you can switch to a short regular 11mm 12 point socket, once you reach the block with deep set socket, to push it through that much farther without switching to the open end wrench).

 

For inserting the tube, lube the block where tube is inserted with WD40 and set the 11mm open end wrench head against the seat ring and gently tap the tube into the block until the seat ring is against the block.  I have removed and installed at least a dozen dip stick tubes in this manner over the years and works perfectly every time.

Note: 7/16" Socket & Wrench will work but 11mm will give you a tighter fit.

I never knew there was a splash shield in the pan area. It all makes sense now on what's going on with the dipstick as its inserted. While inserting my stick it always felt like it was hitting something and turning towards the crankshaft. I had thought that it was hitting the front of the shallow part of the pan. Now I see what it's doing and it jives with what I feel it's doing.

Haha, thanks Anders. If I knew all this earlier I would have fixed it whilst the engine was still apart. But I got the engine back from the machine shop all re-assembled except for the dipstick tube, which the mechanic had broken while trying to remove it. I thought "no worries, they sell them brand new from Caddy Daddy, I'll just press a new one in." not knowing that after they are pressed in you need to bend them about 1/2" an inch.

Ricky Tee. Those are a great pictures. One of the best examples of how good a picture will be in a thread here. You could have written a book on how to fit the pipe and it would still be unclear, now with these excellent pictures all is perfectly clear.

If the 63/64 Chapter had a reward on best yearly picture you should get it. And the price should be a new oil pan gasket set.

Thank you Ricky

As a side note, I remember looking on that picture in the manual about a year ago. Reacted on the bended pipe. Couldn't really understand it and thought it was some printed error. Now I know better. Wonder how many trial and errors the Cadillac engineers had before coming up with this solution. Its kind of a Hillbilly solution...

Definition of "Hillbilly solution": There is always a proper way of repairing things...... then there is the Hillbilly solution.

Thanks for the update with pictures. Confirms all tubes need to be checked when installed regardless of which engine!

Even in the illustration in the 64 Shop Manual you can see that the dipstick tube is bent at an angle.

“Well there’s ya problem!” 

I removed the sump today, the stick was nowhere near where it should have been.

Bent the tube by levering it with a flathead screwdriver, now the dipstick slides in and out easily.

Now I just need to get a new oil pan gasket set.

Yep, I tweaked ours when it was all apart as well.

In the short term, just grab any old dipstick that will fit and cut the end off so you have maybe 12 inches only of dipstick and put that in the tube to seal the engine.

Carry your proper dipstick in the boot until you knock the sump off. At least that way, you can do the rectification job at your own leisure.

The tube doesn't hit, but it needs to be bent to guide the stick away.  We have a few yards in NJ that still had these cars, and the sticks were missing on every one, so i'm guessing it's a very common oversight.

Comment by Ricky Tee on November 26, 2017 at 10:44am
No I don’t think it’s the tube that hits, because I can take the dipstick out and run the motor no worries. But if I put the dipstick back in, it rattles like a bastard and puts a noticeable bend in the stick.

64 Recirc/Fresh Air Door Actuator replaced; FROM THE INSIDE.

Posted by Norman Silverman on February 4, 2019 at 11:21pm 8 Comments

I am happy to report that I have successfully replaced the Fresh Air/Recirc door actuator that is located on the blower box-and have done so without having to remove the blower box. I did it by taking out the glove box and attacking it from the back.  It took several days, LOTS of patience and some band-aids, but it is done. THE most difficult part -BY FAR- is to remove and then replace the screw that sits on the actuator arm, connecting it to the fresh…

Where do the flashers go in my 64 Deville Convert.  I'm thinking that's why both turn signals stopped working.

Source for Motor mounts and Trans mounts 1964 SDV

Posted by Norman Silverman on January 9, 2019 at 4:23pm 4 Comments

Hi.

Where is the best place to purchase good quality motor mounts/trans mounts for my 1964 SDV? I see that Rock Auto has them for $8 and change, and others for $24 and change. Big difference. Is there a better place to buy them from?

Thanks

Norm
