Ok while doing a header swap I broke the dipstick tube off in the block. I tried all the different suggestion's that I could find except the slide hammer, which probably would have worked. So any way the tube is now sitting in the bottom of the oil pan. The question I have is it safe to start the car? What damage can the broken piece cause to the engine? Thanks for your time.

 

You should not have any problems with it being in the bottom of the pan. Next time you do an oil change use some stiff wire to fish it out.

 

Thank you that's a relief. It's been challenging switching to shorty headers, now if I can get the new tube in without destroying it I could have my car out this weekend.

 

I think we've all had those "everything goes to crap" moments.

 

What Tom said....but "IF" you can't actually see the remains of the tube in the block then it most likely fell down into the pan, I mean where else would it go. So, considering the possible cost of the remaining piece of tubing somehow geting caught up in a whipping cranshaft I would drain the oil now and try to fish it out with the wire method or one of the small magnets that's connected to a bendable rod. ..... or drop the pan if that's possible in your chassis. I know that sounds like a lot of work depending on your application but if that little tube got thrown up into a conn rod or piston .......then it would be a helluva lot more work. I hope whatever you do works out...... Dave

 

HUH? The lower end of the tube is like six inches long. Good luck fishing that out through the drain plug hole.


To the OP: Yes, the slide hammer works every time and avoids the headaches that you now have. A bigger hammer is not always the right solution.

 

I thought it was just a couple of inches long. Either way they don't float and will stay at the bottom of the pan.

 

That’s a scary vision Dave. I’ve decided to drop the oil pan. This is a great forum and thanks to everyone who chimed in.

had a knock in my chevy motor,so I pulled it out, pulled the pan and found the 4" piece of dipstick I was missing, caught between big end of con rods,every turn it would hit the pan and block. pull the pan.

 

Where did you get the shorty headers?

 

So what if it breaks off flush with the block; how could a slide hammer be used?

And if there is a remaining bit, do you grab it with a pair of vise grips and then fasten the slide hammer to the grips?

 

Use a self-threading screw that fits tightly in the tube. I've actually made an adapter with the correct size self-threading screw welded head-to-head with a 1/4-20 screw that threads into the end of my slide hammer.

 

Hi Zeeke I bought them from Thornton. Quality is very good. I had to put new motor mounts because the right side was hitting the frame and remove the oil filter housing and dipstick tube which was a whole different issue. I wish I would’ve gotten them to begin with the fit is excellent.

 

I have a loose dipstick tube on my 4-4-2. Tell me more on this slide hammer technique. Photo encouraged.

 

I'm confused. If the dipstick tube is loose, why do you need a slide hammer to pull it out?

 

Doh! I was looking for a way to pop it in fully, not remove it. Probably why I'm not trusted with a slide hammer.

 

If the tube isn't all the way in you could overfill your oil. Best way i found to seat the dipstick is with closed end of an open end wrench, have the tube end chilled and the block warm. To the OP, good plan to remove piece, one less thing to worry about, good luck.

 

The last one I installed was so tight that I feared it would bend or break trying to get it into the block. I ended up lightly sanding the fat section to narrow it slightly so it went in easier.

 

That is how the Supercars Unlimited dipstick tube was to install. The chrome dipstick tubes fit loose like the F85 4-4-2 is experiencing.

 

I had to file the ribs on the new dipstick tube to get it to fit in the block. The broken piece is still in the oil pan where it will stay until I can get on the lift again and take the oil pan down. I put a neodymium magnet on the bottom of the oil pan hoping the broken piece will stick to it.
