Another case of ... Oil on the case.

[Yorch - 1100RT]

Oh my... did my first oil change on my 01 1100rt a few days ago..... took it out

for a run and now I've got a leak.

The picture shows where it's coming down the face.  

Ugh.  

 

 

fwiw - 15-50 mobile1.

slight overfill, but top visible withing the sightglass, when cold.

fram ph3614 (p.o.s.) oil filter.  will see if it could be the issue tomorrow.

filter is a pain to tighten.   do not recommend.

 

no leak on the ground under filter after 2 days sitting there.

 

suggestions and prayers welcome.

Thank you everyone for your feedback.  Several people have suggested that the bolt's bent washer is the culprit.    Today, once the temp goes above 35 (F) I'm going to take it out and straighten the washer.   I am also ordering a whole new bolt from eBay for about $25 that claims to be NOS.  It should include a new rubber washer/grommet, too.   Here's hoping.  :)    Thanks again!

 

(Other good people are chiming in... should this be helpful.   https://www.facebook.com/groups/311318068299/permalink/10159211967713300/)

 

BTW - I spent last night reading.   These bolts only get gently tightened.   Emphasis on "gently".   One guy even said "no sockets! Put it on by hand and that's enough!"

Thank you for starting your own thread.

 

Unless you have wiped the oil off of the lower front of the cover then it doesn't look to me like the that washer or the rubber seal under it is your leak.

 

It is difficult to really tell by the picture but it sort of looks like the bottom of the cover is slightly bent where to oil leak is showing.

 

An educated guess from afar is that you spilled a little oil on the top gasket seam when re-filling it after the oil change & that slowly seeped around the gasket until it ended at the bottom in the lowest place. 

 

Or you have a damaged cover, or damaged cover gasket, allowing the new oil to seep out. 

 

Or even possibly a leaking oil filler cap assembly (oil filler pipe) the "O" ring on those are a known leakage point.  (see below)

 

Clean the cover squeaky clean (including the gasket seam) then ride it few miles, then lightly spay on white foot powder or other light spray powder. That is pretty darn good at showing oil leakage paths.

Good call!   When I do the "bolt fix" later today, I'll be sure to clean everything squeaky clean.

 

Long term plans are to get that aftermarket filler plug that opens with a 7mm hex wrench.

Good for keeping pesky people (upset tenants, upset students, etc.) from messing with your motor.

(Wunderlich "security" fill plug for Oilheads... unfortunately between $50 and $100!   https://www.wunderlichamerica.com/BMW_R1100_R1150_R1200_Dry_Safe_Oil_Filler_Plug_Kit     or  https://www.wunderlichamerica.com/BMW_R1200_C_R1100_RT_R1150_RT_Oil_Filler_Plug)

I don't know how good those work, if I wanted to mess with it just  a quick pry with a screwdriver & the entire fill pipe pops out (locking cap & all).

Well... just cleaned her up and took a spin.   The oil leak returned! 

Too much oil up around the oil filler to be comfortable with.   

A couple drops forming underneath, too.

Note.. that picture was take shortly after getting home.  No clean up following the ride.

 

Thinking that at least a new oil filler assembly may be in order.

Still can't really tell where it is coming from by the picture. But we can see where it ends up. 

 

You probably don't need a new oil filler assembly (oil fill pipe) as it is usually just the "O" rings that leak.

The oil filler cap is a standard metric "O" ring 18mm x 4mm. Probably find that at a good unlevel auto parts store.

 

The lower is also a fairly standard size, pretty sure it is   32mm OD x 24mm ID x 3.5mm (take old one with you to match up size). A standard # 214 "O" ring should also work.

New Valve Cover Gasket sets come with the Bolt Seals & maybe the Spark Plug hole seal, but I haven't found a good source outside of paying 8 times their value from BMW Motorrad.

There's nothing special about the Washer, and if the Bolt's not damaged, there's no need to replace it.

You are replying to a 6 month old thread here!

But we never did get a follow up post from the OP with the resolution, solved or not. Maybe this will prompt a response. (Couldn't help myself also responding to a 6 month old post!)
