Dry Safe Oil Filler Plug Kit

Put an end to the weeping oil filler plug, once and for all!

The original oil filler plug of your bike screws into a plastic insert that's merely pushed into the valve cover. In most cases, it's not the oil filler plug that leaks, but rather the outer ring is the culprit. In addition, the original insert has a small tab that's supposed to keep the insert from turning in the opening. Often times this too fails. If the oil filler plug is accidently over-tightened, the tab can become damaged, resulting in the insert turning along with the plug.

This part is perfectly machined of aluminum and anodized. A two-piece, o-ring sealed assembly replaces the original plastic insert. The parts are screwed together and further secured with screws, making this a very effective and permanent, leak-proof solution. The tamper resistant filler plug that we developed for the R1200 motor is then screwed into this assembly. The result is a great looking oil filler plug that will stop the annoying oil leak as well as would be vandals.

Some facts:

Conversion from the leak-prone, sabotage vulnerable plastic construction to a threaded, R1200 type filler plug.
Absolutely leak-proof plus theft and tamperproof .
The oil filler plug can only be removed with a special key.
One-piece, indestructible filler plug.
Larger than original opening diameter for easier oil filling.
The assembly will not spin in the valve cover.
Beautiful, anodized finish.
The key includes a ring and can be used as keychain.
Special key is included and a spare is available (see under the Related Products)
Easy installation requires removal of valve cover.

Please Note: The associated video contains slightly incorrect information. The screws used to tighten the threaded ring are replaced with set screws after the ring has been tightened. Please carefully review the supplied instruction manual or download it by clicking on the link above.

The Rube Goldberg oil plug

★ ★ ★

B Doore | May 31st, 2017

I've installed this oil plug -- the instructions are clear enough and the product quality is good. It does accomplish what is advertised, however, like other reviewers, I question the need for the special removal tool. While this might be a good option for people in areas where vandalism is rampant, I suspect that most people would opt for a hex head or other standard fastener. The key is tiny and not particularly easy to use -- especially on an faired model like my R1100RT. It is, frankly, also overpriced. While I can appreciate the R&D time, it seems like a lot for what it is. I suppose if these are cranked out in small batches on a CNC machine, then maybe the price is driven by that. All in all, I think manufacturing costs could be reduced by using an off the shelf (maybe even the factory) plug and simply concentrate on the retaining ring. I don't typically write negative reviews, and I suppose the plug does what it is supposed it, but it seems a bit Rube Goldberg solution to me.

Screws used for tightening are too flimsy and bent. Installation was completed and no leak so far but feel that the screws should be slightly larger provide more confidence in the install.

Plug cool. Tool fail.

First time I used the tool for an oil change the small metal piece that fits into the tool cracked off. Or fell out. I don't know but it isn't there anymore. It did not last long. I can't unlock the plug. The tool looks clean in the hole where the lock should be I think it was fitted and glued, not one piece . On the positive side; Leak stopped. Looks clean and flush. Negatives; the tool is a fail. Why do we need the tool ? Who would sabotage the oil? Can I use something else to open it? Is the tool guaranteed ? I emailed, yet to find out. I ordered it in November . Only one oil change! Should unlock with an Hex lock something I can easily replace. Getting rid of the plastic insert in the cyclinder was tremendous. That was was a piece of junk. BMW should have addressed this. There should have been a class action suit. Installing wasn't easy as the YouTube video indicated. It still leaked a lot until I put in a larger o ring.

This is an excellent solution to the problem of the original BMW oil filler plug. The comprehensive instructions are such , that even I could fit the item with complete confidence. The new plug has completely eliminated any traces of leaking oil. This replacement oil plug is what BMW should have designed from the very beginning.

I like the looks, but it still leaks

So I bought this to replace a badly leaking stock cap. Going in on the chrome valve cover was a beast and a pain despite the video. Probably more my fault than anything on that one though. It looks great and it easy to use. It did reduce the weeping oil, but it is by no means gone. Not as bad as it was, but not nearly as good as I'd hoped for the price. Would I still buy it? Yes, but only because I do really like how it looks and not to stop the leaking.

Weep-proof for first time

Since I got the bike new in 1994, the oil filler cap has always weeped oil. A dirty annoyance. With this replacement installed, the weeps stopped and the engine stays clean...for the first time. Fit, finish and installation were perfect.

Worthy Replacement Plug for your R model

This plug kit replaces an older Wonderlich plug that slipped into the factory oil plug seal. However, this plug kit fixes the real cause of oil pushing out the filler - a better seal on the valve cover. Easy to install. I would suggest you remove the set screw from the lock nut before you begin installing the plug into the valve cover. Otherwise, the installation instructions are easy to understand. No buyer's remorse on this product. Thanks Wunderlich!

A most excellent solution to a s^%$^y problem, that sould have been addressed by BMW in production. Install easy, thanks for the four button heads so as to tighten.

The end to dirt and grief

Cost me $103.00. Money well spent. The problem gone once and for all. Today cleaned the oil and the grime from the left side of the bike for the last time. What a relief!!!
