Lower metal oil dipstick tube

[JackOfAllTrades]

Does anyone know how to install a new lower oil tube? Because I am rebuilding a 1.8 and some how the previous owner completely destroyed the top plastic piece that connects it to the top orange piece.

I have looked everywhere and couldn't find anything about how to install this piece

the lower tube is pressed into the block. I dont have any tips on removing it though.

Whats wrong with the lower tube? If it is just the plastic one that is messed up, all you have to do is slide on a new one.

The lower one just pulls out. You might need a pliers, but grab it, give it a little twist while yanking. Maybe take pointers from that hoe down the street?

New one is easy to install. All you do is-

The dipstick assembly is 3 pieces.
A metal tube press fit into the block, a plastic tube clipped onto the metal one, and the actual dipstick itself.

I highly doubt you or the previous owner broke the metal one. That said, all you need is a new plastic tube to clip onto the metal one.

No the actual metal dipstick tube was messed up, when I got the car, they had a piece of metal pipe stuck into a rubber hose clamped onto the lower tube, because where the plastic piece pressed into the metal tube was completely gone

Wonder how they messed it up that bad...

Refer to above to remove and replace it.

No idea, but I bought the car to rebuild to engine so it didn't matter that much to me

But if I press on the top part of the metal tube it won't break the piece at the top that has the o-ring on it?

That's how I put mine back in. Light taps

So I know this is an old thread, but I am in the same position as OP. I am doing a breather hose replacement on my 1.8 B6 and broke the stupid top orange dipstick piece while working in the bay.... 20 year old brittle plastic...... I had to pull the remnant of the orange pipe off the block metal pipe, and while doing that I cracked the plastic top of the metal pipe and it disintegrated. It does have a plastic top on it to mate up to the upper plastic funnel, and they don't sell just that piece. You can buy the OEM style block tubes with the plastic tops on them, and in this situation you may have luck extracting just that piece off a new one and put it onto the block tube instead of fully replacing it, but that would just be a backup plan for me.

They sell an all metal lower dipstick design option though (no plastic top) and I bought that one. I read people saying to extract the block side tube you go in through the bottom after removing the oil pan and tap it out from underneath. I looked at the oil pan today and no freaking way am I getting that off easily. Even if I could get to all the bolts I don't know if I could physically get the pan out over the subframe.

Regardless if I am just being needlessly intimidated by the oil pan, I am going with another option. I've tried pliers and vice grips and they did nothing. That tube is in there way too good to wrangle it out by just pliers and twisting. My new plan is to use a pilot bearing puller with slide hammer on the tube. The pilot bearing puller expands out and will hopefully grip tight enough that i can use the slide hammer to extract it. Will try to post with a pic if it works.

I had this exact issue with my son's A4. I think we ended up harvesting the plastic top off of a new lower tube. Issue is that the upper does not grip the bottom well anymore. I've tried several upper tubes (including Genuine parts) and it tends to pull off when checking oil if you don't hold it down with something while pulling the dipstick.

I think I remember that the tip came off really easy of the new lower.

Ok, so status update on my previous plan. I bought the slide hammer with pilot bearing attachment, and no matter how hard I tried, that lower dipstick tube would not extract from the block. The attachment would pull out of the tube every time. I probably hammered on it dozens of times each attempt, and the tube never even pulled out of the block by a fingernail's thickness. Those things are in there for keeps. I tried wrenching it back and forth but the metal started fatiguing and it felt like it was going to snap off at that base. I recommend against trying that.

I ended up going with the backup plan, using the plastic end of a new tube I bought off Amazon($15) that KW and I mentioned up above. Once you pull the plastic end off the new tube, you'll notice it was barely glued on as some dried glue will flake out of the end. You may want to re-glue it to the old pipe once you put it back on, although I didn't as my situation was different. Because I had used the pilot bearing puller on the tube, it had the effect of flaring the tube out about 1-2mm so it took a bit of force to put the plastic piece back on. I felt like once it was done though, it was secured better than even the glue had held it. I found that a 19mm 12point deep socket would hold the plastic piece perfectly, and with a 1 foot extension on a 3/8 drive breaker bar I was able to position the plastic piece onto the oil tube and hammer it on till it bottomed out. Then I put the new oil funnel (orange tube) back on the top of it and it snapped on firmly.
