Happy Thanksgiving everyone.
I just placed an order at GOWESTY (10% OFF!) for a Haynes repair manual that should have the specs but with the day off today I was hoping to tackle replacing the oil filler tube on my 83.5 Vanagon Westfalia.
The reason for the filler tube assembly replacement is that the current plastic filler on the metal tube is cracked everywhere and being held on by what appears to be large amounts of electrical tape.
I found a complete and in tact filler tube (see pictures) at a local VW yard in Colorado Springs for only $20! The plastic isn't cracked and the metal pipe looks good as well. I have the oil filler tube gasket in hand (Bus Depot) and will use thin layers of RVT as well on the mating surfaces.
What is the torque specs for the NUTS holding that filler tube onto the engine block?
I was able to loosen the lower nut (I was surprised the tube wasn't held into place with bolts!) but am having a heck of a time getting a 13mm socket onto the top nut. Open end wrench? Can't toque with that though.
I am in the middle of an oil change so the crankcase is empty (I wasn't sure if oil would leak when I removed the filler tube?)
I was also going to ask about the drain plug gasket torque specs but did some research and found a post referencing "18 ft/lbs is the correct torque per the Bentley manual." (anyone disagree )
Thanks in advance!
Travis

These are just standard strength 8mm fasteners IIRC, you manual will give a spec for such. Personally I wouldn't dream of using a torque wrench on such a part as this, we aren't building a space shuttle or the like here. Just don't be a gorilla when tightening them down nor leave them lame wrist loose. |

A swivel socket might work. I have 10mm and12mm swivel sockets from Snap-On, but can't find swivel sockets in their online catalog. Harbor Freight has impact swivel sockets, but they are fat. Try chasing down a Snap-On truck and see what they have.

Snappy 1/4" extra shallow socket, universal, extension, 1/4" driver.
I use a gasket and The Right Stuff sealant, 17ft/lbs. |

Thanks for taking the time to share thoughts/ideas.
I was able to remove the upper nut with a 3/8" 13mm shallow socket, 1/4 to 3/8 adapter, and a 1/4 craftsman socket (crappy...toy like!)
Got the old tube removed and new tube installed. Couldn't torque the nuts so I snugged them. Being in the bicycle industry I have learned to rely heavily on torque wrenches...under/over torque a carbon part is dangerous. I do need to get better at "feel" and lose the torque wrench crutch.
I posted a picture of the cracked filer tube....any reason to save/donate it? I plan on cleaning up the metal tube and selling...
Thanks again for helping out a newbie. My next project is replacing the interior door panels (fronts/sliders) with ABS. I bought a huge sheet from a local supplier and am cutting it out with a jig saw. Plan on painting it Espresso with Krylon plastic paint. After that got an aux battery install and a complete fuel line replacement (might wait for warmer times so the garage heats up more and the tubing is more pliable!)

i have a 13mm wrench ground down for nuts like this one, i ground the edge of the ring end, then ground into the side of the wrench, to a 2" arkabout a 3rd of the width of the wrench. _________________ lucy our westy

This was the only thread I could find about the oil filler neck. Anybody know a trick to join the upper plastic and lower metal parts? Engine I bought came with both but they're separated. Forcing it is always my last resort... _________________ TheVanTracker.com - Kill Switch + GPS Tracker + Door-open alerts, made specifically for the Vanagon!

I got a box wrench up there, flip it over every 1/16 turn. _________________ Eric

Man I'm sorry to be dense, but what do you mean? use a small box wrench from the outside, pry the lip up and go around slowly prying it up and trying to get the metal into the plastic?

Getting the plastic part of the filler fitted to the metal part can be difficult once the plastic is old and deformed. |

Heat the bottom of plastic tube real well with a hair dryer or VERY carefully with a heat gun. Then massgage it back on to the metal tube. If you look at the bottom of the tube where it mates to the metal you will see there is a female channel where it connects. Make sure this is somewhat spread and not too deformed. Again heat is your friend but not too much as you do t want to melt the plastic. But not enough heat and you can crack it. Massage it on with a twisting motion
Good luck |

I'm going to relight this fire instead of starting a new thread. If that's not the best way to do it, feel free to correct me. 86 waterboxer, just reinstalled and filled with new oil. Oil dripping from lower metal end of the oil filler tube where it meets with engine block. First I installed the pipe with no gasket, metal on metal, and it dripped, maybe one drip every few minutes. Drained the oil, removed the pipe and its annoying upper nut, and reinstalled with new green gasket from Reinz kit. Leaks just as much now. With all the hundreds of things that need to be done when reinstalling an engine, I didn't think this would be an issue. Any suggestions for blue gasket maker or any other product? Also, would I use it WITH the current green gasket or instead of. And why the heck is it leaking anyway? Thanks, Bob |
