    Excessive oil leaking

    Hi all,

    Went down to hop on my bike after work and notice a couple of drops of very black oil beneath it. Thought, hmm maybe from another bike, but when got home and parked up I noticed a couple more. On closer inspection I can see this:



    Its the LHS very near the gear shifter, all of the stuff below is covered in black sludge.

    I checked the Sump nut and all dry as a bone there - and also I can still see the lovely fresh clean synth oil in the oil window from my recent oil change.

    The only thing I can put it down to is that I pumped the Scottoiler up to 40s recently - could this be causing a build up near the front sprocket and that's whats dripping down - the oil was really black and gunky.

    Or could this be a more serious sign? The oil level in the window seems fine to me at the moment.

    I know the simple way to test is just to back off the Scottoiler but I don't want to damage the engine if it is a leak.

    Your Scottoiler could well be the culprit.  It uses a light oil designed to fly away as it goes round the sprockets carrying grime and grit with it.  Normally this is when you are riding and the tiny amount of spatter goes off onto the road.  However, some lands on the bike, so over time a black oily deposit can build up around the sprockets.  I use brake cleaner to remove it. 

    If it is dripping onto the ground when stationary then unless you are leaving the engine running, you are probably using too much oil and need to turn it down a touch.  I time mine at 1 drop every 45 secs and this keeps the chain and sprockets in great condition and gives minimal spatter without any stationary drips.

    SXH - that's one of the main reasons I stopped using Scottoilers. I couldn't control the darned thing with sufficient fidelity to find a good compromise of oiling rate plus it did still create a build-up of sludge around the front sprocket irrespective of what I did.

    I moved onto the Cobrra Nemo 2, which I think is a much better system, but still I have ditched that too - I found that the nozzle kept moving away from the chain/sprocket so the oil wasn't guaranteed to end up where it was needed.

    Now I know that my chain is getting enough lubrication at a regular mileage (500) because I clean then lube with Wurth Dry Chain Lube every weekend which is a little over 500 miles commuting for me.

    I got the Scottoiler for peace of mind really as I was terrible at chain lubing with previous bikes, however, I know realise that I have grown a bit since then and am mostly a responsible adult these days and given the mileage am on a similar interval to you.

    I tend to cover 300 miles a week so at the weekly bike wash I inspect the chain and wax it, if not this wash, then the next.

    I was just wondering where the stuff had come from - I do think the oiler is the culprit. My fault though for turning it up to the max because the way the garage positioned the nozzle is not where ScottOiler recommend to it tend to miss the chain more than it hits it so I was sending more oil through the system to get more on the chain.

    Will do a degrease this weekend and monitor.

    As an addendum to this post. I was cleaning my chain over the weekend and decided to use some scottoil rather than dry wax - I forgot quite how anti fling scott oil is.

    I may have gone a bit gung-ho, but after a good chain soaking I went for a spin which caused a ton of fling on the rear wheel but also more oil to pour out from the place identified at the start of this post - thereby satisfying me that I just had the Scottoiler turned up too much originally.

    Now next question. Is there an easy way to get to the front sprocket to degrease it :) ?
